Chapter 1: Introduction Introduction to the Backup Server The Backup Server is a key element of the complete backup and restore operation and incorporates many features that simplify setup and administration and reduce total cost of ownership (TCO). In addition, by capitalizing on the stability and security offered by the Windows NT operating system, the Backup Server permits safe and secure backup and restore over any TCP/IP network. Operating as a native NT Service, the Backup Server incorporates multithreaded functionality, permitting thousands of simultaneous backup and restore sessions on a single server. Furthermore, thoughtful design of the user interface translates to ease of use and permits maintenance of every aspect of the Backup Server s operation from a single point. The revolutionary FastBIT technology further enhances the Backup Server by permitting large files and the ongoing changes to those files to be stored in the smallest amount of space. FastBIT also reduces the time it takes to do a backup whether across the room or across the world. More on the FastBIT Backup With a FastBIT backup, it is only necessary to backup the changed bytes after the initial backup. These changes may represent additions, deletions and/or modifications. Furthermore, the process can be used to backup any type of file including database, text and executable files. This is possible because the process utilizes an intelligent binary comparison algorithm designed to work on every file. By incorporating the concept of a FastBIT backup, incremental backups are reduced by an average of 85 to 99 percent. This translates into a significant reduction in transmission time. 1

Overview of the Backup Server NT Integration The Backup Server is an automated server application that runs on Windows NT/2000 as a service. It is implemented as a multi-threaded application to allow multiple client requests to be processed in parallel and uses Windows sockets as the communications channel. The server listens on a specified port (default port is 308) for clients to request backup and restore operations. Since the Backup Server is highly integrated with the NT/2000 security model, it performs client authentication through the local Windows NT/2000 system (workstation or stand-alone server) or the Windows NT Primary Domain Controller for the domain specified in the Windows NT/2000 server installation. User Authentication Since the Backup Server is highly integrated with the NT/2000 security model, it performs client authentication through the Windows NT SAM database, Microsoft Site Server Membership Directory or any standard LDAP database, including Windows 2000 Active Directory. For Windows NT Authentication, users can be authenticated on the local Windows NT system (workstation or stand-alone server) or the Windows NT Primary Domain Controller for the domain specified in the Windows NT server installation. Windows NT authentication is achieved using the challenge/response method (commonly referred to as NTLM), which is the most secure method of authenticating users. For Membership Authentication, users can be authenticated using the clear-text/basic method or the challenge/response method (commonly referred to as DPA). The clear-text/basic method is the common method for authenticating users against the Membership Directory. For LDAP authentication, the administrator must configure the LDAP server name or IP address, the LDAP server port and the base distinguished name (DN) that users will be authenticated against. Also, specific credentials (username and password) must be set on the Backup Client for this authentication method. In other words, existing logon credentials cannot be used. Secure File Transfer The Backup Server utilizes a secure proprietary binary protocol for the transfer of all data. This secure framework guards against the possibility of an outsider capturing data while it is in transit between the Backup Client and Server. Encryption In order to ensure that the transfer and storage of data is secure, an encryption scheme is negotiated between the client and the server. The encryption scheme is used to encrypt/decrypt the proprietary protocols that are used to facilitate communication between the client and the server, as well as the 2

files themselves. The backup files are encrypted during the transfer and remain encrypted as they are stored on the server. Warning: Use of Anti-Virus Applications with the Backup Server In order to run the backup server and anti-virus applications together, you must "exclude" users data directories and the Backup Server's temporary working directories, if different from the data directories, from the scan list. Refer to your anti-virus application documentation for the necessary steps. The actual paths of users data directories will vary depending on how you've configured your Backup Server, but if you have multiple paths for users data, them you must exclude all of them. Further, if you've configured the working directory to "Use the account's data directory ", located under the Directories Tab of the Backup Server Configuration Manager, then excluding the user data directory is all that is required. However, if you have selected "Specify a work directory ", you must also specify that path in the anti-virus exclude list. 3

Chapter 2: Installation Backup Server System Requirements Operating System Windows NT 4.0 Workstation or Server Windows 2000 Professional, Server, or Advanced Server Windows XP Professional Hardware Pentium Class machine with 32 Megabytes of RAM (64 MB Recommended). 5 MB Disk Space for program files. Additional space required for processing and storing backup files. Network Interface Card and/or Modem. Network TCP/IP must be configured properly in your Network settings. If you plan to have clients connect via direct dial-up connections, the Remote Access Service (RAS) must be configured. (To find out more on configuring RAS, go to Help under the Windows NT Start menu and look in the Index for Remote Access Service ). By default, the Backup Server uses port 308. 5

Installing the Backup Server If a previous installation of the Backup Server exists, and you wish to retain current licensing and/or user configuration information, see Upgrading an Existing Backup Server installation on page 10. To install from the self-extracting executable file: Simply run the.exe file. To install from a downloaded Zip file: Unzip the file into an empty directory. Be sure to retain the original directory structure of the files when extracting from the Zip. For PKUNZIP, use the /d option to retain directory structure. For WinZip, select the Use Folder Names checkbox before extracting the files. 1. Go to the Disk 1 directory from the directory containing the extracted Backup Server files. 2. Run the Setup.exe program from the Disk 1 directory to install the Backup Server files and create the Backup Server NT service. To install from CD: 1. Insert the Installation CD in the CD-ROM drive. 2. Run Setup.exe from the disk to install the Backup Server files and create the Backup Server NT service. The Install Wizard will prompt you for the following information: 1. Enter the directory where the Backup Server should be installed. 2. Choose an authentication option. This indicates how Backup Clients are authenticated when they connect to the Backup Server. The Backup Server is highly integrated with the NT security model. The choices are: Use the Username only for Authentication If this option is selected, the user name will only be verified against the Backup Server configuration database (i.e. Backup Users configured through BackupServerUtil.exe). No password verification is performed in this mode. 6

Use Windows NT Local Authentication If this option is selected, authentication will be performed against the Windows NT User Accounts Database on the local server. This is achieved through Challenge/Response mechanism often referred to as NTLM (Windows NT Lan Manager) authentication. This type of authentication will attempt to use the current Windows logon credentials before requiring that a password be entered. Use Windows NT Domain Authentication If this option is selected, authentication will be performed against the Windows NT User Accounts Database on the Primary Domain Controller. This is achieved through a Challenge/Response mechanism often referred to as NTLM (Windows NT Lan Manager) authentication. This type of authentication will attempt to use the current Windows logon credentials for the domain before requiring that a password be entered. Use Membership Authentication (Clear-text/Basic) If this option is selected, authentication will be performed against the Microsoft Site Server Membership Directory. In this authentication method, the client always sends the supplied credentials (user name and password) to the server. The credentials are always transmitted in an encrypted manner. This is the most common method used for authenticating users against the Membership Directory. Use Membership Authentication (Challenge/Response) If this option is selected, authentication will be performed against the Microsoft Site Server Membership Directory. This is achieved through a Challenge/Response mechanism often referred to as DPA (Distributed Password Authentication). This type of authentication will attempt to use the current Windows logon credentials before requiring that a password be entered. Use LDAP Authentication If this option is selected, authentication will be performed against a standard LDAP database. The LDAP server name or IP address, the LDAP server port and the base distinguished name (DN) that users will be authenticated against must be configured. If the LDAP directory is Windows 2000 Active Directory Services, the appropriate checkbox must be checked. Also, specific credentials (username and password) must be set on the Backup Client for this authentication method. In other words, existing logon credentials cannot be used. 3. Enter a username and password. This will be the logon account for the Backup Server NT service and it should have administrator rights since the service is responsible for authenticating users. If you chose to authenticate through the Primary Domain Controller, also enter a domain name. This is the domain name that was specified when you installed your Windows NT server. 7

4. If the Backup Server was previously installed, choose which previous information, if any, which should be migrated to the new installation. There are options to migrate previous licensing information and/or to migrate previous configuration information. 5. Lastly, the Backup Server help file may be viewed before exiting. Once the Backup Server has been successfully installed, the next step is to add users with the Backup Server configuration utility (BackupServerUtil.exe). Uninstalling the Backup Server The Backup Server can be uninstalled by running Add/Remove Programs from the Control Panel and selecting the Backup Server application. The following options are available when uninstalling the application. The default is for all options to be checked. Account Information Delete the configuration database If this option is checked, the configuration database file (BackupServer.mdb) will be deleted. Delete the account data directories If this option is checked, the user data directories and their contents for all backup user accounts will be deleted. The user data directories hold all backup data for backup users that are configured. Delete the account profiles directory If this option is checked, the account profiles directory and its contents will be deleted. The account profiles directory holds duplicate copies of all user profiles. Log Information Delete the master log file If this option is checked, the master log file (MasterLog.txt) will be deleted. The master log contains overall server information and high-level user information. Delete the account log files If this option is checked, the individual user log files for all backup user accounts will be deleted. User log files contain detailed information about particular operations that have been performed for a user account. 8

Miscellaneous NovaNet-WEB Server Delete the redundant file list file If this option is checked, the redundant file list file will be deleted. The redundant file list file contains specific files, file names and file types that are excluded from backup, even if individual clients have selected those particular files. Delete the upgrades directory If this option is checked, the upgrades directory and it s contents will be deleted. The upgrades directory holds any software upgrades that the server sends to clients that request to be upgraded to a more recent version. Delete the backup server work directory If this option is checked, the work directory and its contents will be deleted. The Backup Server uses the work directory as a temporary directory.

Upgrading an Existing Backup Server Installation To upgrade an existing installation: 1. Stop the existing Backup Server service through the Control Panel (Windows NT) or Administrative Tools->Services (Windows 2000). 2. Reinstall the Backup Server over the existing installation. The original Backup Server database will be copied to a subdirectory called Previous Databases. 3. The setup program will detect an existing installation and there will be a screen displayed called Migrate Previous Backup Server Options. The following message will be displayed: "An old Backup Server configuration database was detected in your install directory. Please choose the types of information you would like migrated to the new installation." Backup Server licensing information If this checkbox is selected, your licensing information will be copied over into your new configuration database. You can change your authentication type between installations, and the license will be migrated successfully. However if you wish to change your licensing mode from per seat to per time or vice versa, unselect this option and a new license will be created. Backup Server options and account information If this checkbox is selected, all of the configuration settings and the user account information will be copied over into your new configuration database. Backup Server transactions If this checkbox is selected, all of the entries in the Requests table in the Backup Server database will be copied over into your new configuration database. 10

Auto-upgrade Feature for Client Software The Backup Server can automatically upgrade a client that connects to it by sending any available upgrades for the software. The latest client upgrade files are always shipped with the installation of the Backup Server. Upgrade files should be placed in the specified Upgrades directory. Multiple upgrade files can and should be placed in this directory if they are available. The next time a client connects, the Backup Server is prepared to transmit any upgrades to the client software upon request. The client will notify the server of its current version and the server will determine which upgrades, if any, need to be transmitted. The server will not upgrade a client to a version that is more current than the server s own version. NOTE: It is important that the client upgrade files not be renamed. 11

Chapter 3: Getting Started Starting the Backup Server Service For Windows NT, from Control Panel->Services, select the Backup Server service and click the Start button. For Windows 2000, from Administrator Tools->Services, select the Backup Server service, go to Properties and click the Start button. The Backup Server service is created with the Automatic start-up option, so this service will start automatically when Windows NT is booted. If an error occurs, it may be due to one of the following conditions: The Configuration database (BackupServer.mdb) was not found or could not be opened. The Backup License Identification Number could not be validated. One of the Backup Server listeners could not be started on the specified port. There was a domain name error, indicating either that the domain controller for the domain could not be found or that he domain name itself could not be found. Once the service is running, many configuration parameters can be changed with the Server Configuration Manager utility. If an option is changed that requires the service to be stopped and restarted, a message box will indicate this. Otherwise, the next time the configuration is read (specified by the database update interval that is chosen), the new changes will take effect. Stopping the Backup Server Service From the Control Panel/Services (Windows NT) or Administrative Tools->Services (Windows 2000), select the Backup Server service and click the Stop button. The service will not stop until currently connected threads have completed processing. The listener thread becomes inactive when the Stop button is pressed to prevent new connections from occurring. However, any existing connections will be permitted to conclude the session before the service terminates. 13

Server Administration Features Redundant File Elimination Recover from Image The Recover from Image concept takes advantage of existing PC procurement procedures and enables a disaster recovery capability to each user. For example, many corporations with a large installed base have devised a standard installation for every desktop to minimize technical support. Since these programs are readily available, the backup software can be configured to only backup files that are unique to each user. This is accomplished by using the Redundant File features, which will automatically exclude the standard files from the backup set. This will significantly reduce the total storage space required on the server and increase the speed of the backup for each user. When it comes time to recover from a hard drive failure, the standard image is combined with all of the unique files that have been backed up to quickly rebuild the user s entire computing environment. Redundant File Manager Utility The Redundant File List Manager is a utility that is installed as part of the Backup Server and used by the administrator to create the Redundant File List that is automatically distributed to clients that connect to the server. This utility allows the administrator to create several different lists and provides an importing capability for combining multiple lists into one. Standard Redundant File Lists may be provided for common applications such as Microsoft Windows 95/98/NT and Microsoft Office. Clients can also share Redundant File lists to ensure that only unique user data is backed up to their servers. Redundant File Criteria A Redundant File List can be composed of three different types of exclusion rules: Figure 1 Redundant File List Manager 14

Specific File - This will scan all the file contents and exclude any files that match identically. File Names - This will allow the administrator to create a list of file names to ignore, regardless of file size or content. File Types - This will allow the administrator to create a list of file extensions to ignore. Similar to an exclude filter. 15

Tamper-Proof Client General With the tamper-proof client feature, the administrator has the ability to "lock down" or block certain functions on each client. At any time, the administrator can view or change the settings that control the options and functionality that are made available to each client. This could be used to prevent users from changing backup schedules or changing file selections. Options Available for Blocking The administrator can control over twenty different options. The following list includes the categories of options and individual settings that can be administered: Functionality Block the user from backing up Block the user from restoring Block changing to a different backup set Block file selections Backup Sets and Schedules Block the configuration of backup sets Block the configuration of schedules Filters Block the configuration of filters Block the application of filters on folders Tools and Toolbars Block the configuration of tools Block the configuration of toolbars General Options Block any or all 5 tabs Backup Options Block any or all 6 tabs Restore Options Block the Restore Tools Tab Figure 2 Tamper Proof Options 16

Quota Management NovaNet-WEB Server General The quota management feature allows the server administrator to better control how much disk space is used by individual users. This feature helps to alleviate situations where a small number of users are occupying a large percentage of the available disk space. In addition, the server administrator can configure notifications (i.e. e-mails, event logs, alerts) to be issued in particular quota situations ( near quota, at quota, over quota ). Quota Limits In order to set quota limits, quota watermarks (i.e. thresholds) are used. The three watermarks are near quota, at quota and over quota. The server administrator can Figure 3 Quota Settings control, on a percentage basis, the below quota and over quota settings. The defaults for these are 90% and 110% respectively. The at quota watermark is always automatically set to 100%. The administrator can also specify what action is to be taken in each quota condition, as well as customized error messages to be displayed in logs and error windows. Client Delete Feature When a quota condition is encountered, the backup user has the ability to remove files immediately and permanently from the server storage. In this way, the quota condition can be remedied by the end-user. The ability for users to delete files directly is configurable by the server administrator in the Client-blocking settings. 17

Low Disk Space Management General The Backup Server has the capability to detect when a low disk condition is reached for accounts user data directories, as well as the Backup Server Work directory. When the server detects that a volume has fallen below 100 MB, an error is logged, and any notifications that have been configured on the server are issued. Backup Disabled if Low Disk At the beginning of a client operation, the server verifies that a minimum of 100 MB is available on the volume for the account s data directory. The work directory is also checked since it is used to prepare files to be downloaded for restore requests. The client operation will not proceed if adequate space is not available. Also, if a disk full condition is reached during an individual file transfer (i.e. middle of a backup operation), the incomplete uploaded file will be deleted and the backup will not proceed further. An error will be issued on the client and the server. 18

NT Performance Monitor Integration General The Backup Server exposes more than 20 data points that can be viewed in real-time or tracked over a period of time. This provides system administrators with detailed up-to-the-minute performance information to help monitor and manage their growing end user backup solution. Pre-configured Settings A new tab in the Backup Server Configuration Manager displays some pre-installed Performance Monitor settings, or groupings of individual counters that are ready-to-use. With the ability to activate these settings, tracking the Backup Server s performance becomes virtually effortless. The following list includes some of the pre-installed groupings: Active Snapshot Client Upgrades (heavy duty) Client Upgrades (light duty) Connectivity (heavy duty) Connectivity (light duty) Server Performance Totals (heavy duty) Totals (light duty) Example: To the right is an example of Backup Server performance counters displayed in the Performance Monitor: Figure 4 --NT Performance Monitor Integration 19

Security and Restore Features Data Encryption Encryption Types User data and the protocol messages used to facilitate client/server communication are always encrypted during transmission, and files are stored on the server in an encrypted manner. File and protocol encryption is based on one of three encryption algorithms: Blowfish, Triple-DES, or DES (Triple-DES not available in International version). The encryption type is configured in the Backup Client software. Setting a Secret Key The user can supply a secret key in addition to the authentication password, which is sent to Backup Server every time the client connects and is used for encryption. The Backup Server authenticates the user and then validates the secret key before access to the account is allowed. The user can change the encryption type and/or secret key at any time and the server will record a history of the change. The secret key mechanism also allows multiple computers to backup separate volumes using separate secret keys to the same user account. This prevents users from being able to view data belonging to other users who are backing up to the same account. Master Decryption Key Feature Setting the Master Key Option The master decryption key is a universal key that is configured in the Backup Server to give the server administrator the ability to retrieve any user s data, if necessary. However, the Backup Client has ultimate control over whether the administrator can retrieve a user s data with this master decryption key. In order to set or update the master decryption key, the correct password for the Backup Server must first be supplied. This is the password for the administrator account under which the Backup Server was installed. Also if the master key is being changed, the previous key must also be entered. The master key access option for a particular account is set in the User Properties window. It should be noted that if the master decryption key option is not being used or if master key access for a particular account is disabled, and the user forgets or loses their secret key, the data cannot be recovered. Guaranteed Secure Client In order to provide a guaranteed secure client in situations where this is desirable, the Backup Client includes an option Block the backup if the administrator can recover my data. If this option is set, when the client connects to the server, the server will inform the client whether or not master key access has been enabled for the particular account. If it is enabled, the Backup Client will not backup 20

any data. Since these options are mutually exclusive, either the user or the server administrator needs to change the relevant setting before backups will be possible. Recovering Data As mentioned earlier, in certain situations, it may be necessary to allow the administrator to recover users data (e.g. in the event of a lost or missing encryption key). To recover data, the master decryption key is entered as the password in the Backup Client software to connect to the particular user account. The server then attempts to validate the user and detects that the master decryption key is being used. If the user authentication is successful, the Get Volume List from Server and Get File List from Server options in the Restore Tab can be used to display the volumes and files that are available for restoring. Files can then be selected and retrieved from the server. Previous Version Restores Setting the Restore Window The Backup Server has the capability of storing multiple versions of the same files. These older versions are available to the user as long as they are within the configured Restorable window for that user account. Once old versions are no longer within the restore window, they are deleted from the server. The Restorable window is set for a particular account in the User Properties window. The default restore window is 1 month. If it is not desirable to save previous versions of files on the server, the window should be set to the minimum of 1 day. Available Versions At the very least, a single version of each file will always be kept on server even if it was not backed up recently. This applies to files that have not been deleted from the user s backup set. If a file is deleted from the backup set, then any old versions within the current restore window will still be available. Although this is true, once the last version is no longer within the current restore window, it will be deleted from the server. When the user runs the Backup Client software, and selects Get File List from Server, the server will notify the client of all the files and individual versions that are available for restoring. 21

Data Restore Wizard Restorable Media Sets The Backup Server offers the capability to create restorable media sets that can be written to CD-ROMs or other media. The Backup Server includes a Data Restore Wizard, which allows the server administrator to prepare an account's data so it can be immediately restored by the user from local media. The wizard also divides the data into multiple pieces of a specific size if the user's data will not fit on a single piece of media. The user's data is kept encrypted on the media as well, and can only be restored if the proper secret encryption key is known. Figure 5 Data Restore Wizard Restore-only Client In order to restore the data contained on the media, a Restore-only backup client program is included on the media. The media also contains an autorun.inf file to allow autorun media (CD- ROM) to automatically start the Restore-only Client. 22

Configuring Backup Users Adding New Users To add a new user: 1. Run the Backup Server Configuration Manager (BackupServerUtil.exe) 2. From the Backup Users tab, click on the Add button. The User Properties window will be displayed. 3. Set the desired configuration parameters for this user. For more details on these parameters, see The Account Properties. As an added convenience, when adding a new user, the application will automatically detect the most common directory names already configured for other users. It will set the default directories based on these path names and the new user name. The Backup Server will detect the added user the next time the configuration database is read. Otherwise, to have the change take effect immediately, the service must be stopped and restarted. Modifying Existing Users To modify an existing user: 1. Run the Backup Server Configuration Manager (BackupServerUtil.exe). 2. From the Backup Users tab, click on the Properties button. The User Properties window will be displayed. 3. Modify the desired configuration parameters for this user. For more details on these parameters, see the User Account Properties Window. If the Backup Server needs to be restarted because of a changed option, you will be notified with a message box. Otherwise, the Backup Server will update the changed information dynamically the next time the configuration database is read. For example, user accounts may be added/deleted or enabled/disabled dynamically. There are also individual account settings that may be modified dynamically. NOTE: In order to change the user data directory for a particular account, it is recommended that the service be stopped, the contents of the old directory moved to the new directory, and the service be restarted again. 23

Removing Existing Users To remove an existing user: 1. Run the Backup Server Configuration Manager (BackupServerUtil.exe). 2. From the Backup Users tab, click on the Remove button. 3. As an added feature, a message box will appear to allow the application to automatically delete all associated directories for that user. The Backup Server will detect the deleted user during the next time the configuration database is read. Otherwise, to have the change take effect immediately, the service must be stopped and restarted. 24

Logging and Error Notifications Receiving Error Notifications The Backup Server offers a number of ways to signal the administrator that an error has occurred in the server processing. Each method is a configuration option and can be set to handle one or more types of error conditions. The following types of notifications can be issued: E-mail E-mail notifications allow e-mail recipients to be notified under specified error conditions. The Backup Server uses the mail industry standard, SMTP, to connect directly to an SMTP e-mail server and deliver e-mail notifications. Event Logs Event logs allow error conditions to be written to the Windows NT/2000 application event log. For event logs to be written, the Event Log service must be running on the server. These events can be viewed in the Windows NT/2000 Event Viewer. Alerts Alerts allow designated recipients to receive administrative alert messages for specified error conditions. The recipients are configured through the Server Manager on Windows NT or the Srvmgr.exe utility on Windows 2000, and they can be computer names or the names of loggedon users. Alert messages are sent as Windows NT/2000 messages from the server to a user s computer. For alerts to be sent, the Alerter and Messenger services must be running on the server. For alerts to be received, the Messenger service must be running on the destination computer. The following types of error conditions can cause a notification to be issued: Exceptions An exception indicates that the Backup Server generated an application error, such as a file exception or a memory exception. 25

NT System Errors A system error indicates that the Backup Server service could not be started due to a system error. Backup/Restore Errors A backup or restore error indicates that a Backup Server processing error occurred while a backup or restore request from a client was being serviced. Connection Failures A connection failure indicates that a low-level connection between a Backup Client and the Backup Server was prematurely terminated or received an error. Authentication Failures An authentication failure indicates that a user is not configured for the Backup Server or that a user cannot be authenticated against Windows NT or the Microsoft Site Server Membership Directory. Low Disk Space Errors A low disk space error indicates that the Backup Server is running out of available disk space for account data. Licensing Warnings/Errors A licensing error indicates that the current Backup license has expired or that the computer limit for the current license has been exceeded. For more information on configuring notification methods and errors, see the section titled Notifications Tab. 26

Viewing Logs The Backup Server maintains two types of log files: the master log file and individual user log files. Master log file A master log file is created when the Backup Server service is started. Overall server information as well as high-level user information is recorded. Master log entries also cross-reference user log files so detailed information can be viewed if necessary. Once the maximum size (configured using the Backup Server Configuration Manager) is reached for the master log file, the current log file is moved to an archive file in the same directory and a new master log is created. The master log is located in the Backup Server install directory by default or in another specified location that s configured through the Backup Server Configuration Manager. The file is named MasterLog.txt. User log files Individual user log files are created each time a client connects to the Backup Server and requests that a server operation be performed. These user logs provide a detailed account of the operations that are performed, including lists of file names, dates, and sizes. Upload and download times are also indicated. User log files are located under a sub-directory named Logs that resides under the install directory or other specified directory. Each user s logs are kept under the Logs sub-directory in another sub-directory that is the same name as the user account name. Each user log file is named with a date/time stamp immediately followed by a one-character identifier that indicates which type of operation was performed. (B =Backup, R=Restore, L=List, D=Delete, E=Error) User log files can be deleted automatically by the Backup Server by configuring the maximum number of user logs that should be saved for each user. 27

Troubleshooting Errors Listed below are some of the problems you may encounter when running the Backup Server. It is important to check the log files frequently to monitor the activity of the Backup Server. For more information, see Viewing Logs on page 27. Errors during Installation If you are re-installing the product and receive an error that indicates that the service could not be removed or could not be deleted, make sure that the Backup Server service is stopped (look in the Control Panel under Services). Errors when starting the service If you receive a logon error when attempting to start the Backup Server service, verify that your administrator account has the user right to log on as a service. The installation process attempts to set this right for you, but it can also be set manually from the User Manager under Policies and User Rights (the Show Advanced Rights checkbox must be selected). Various errors are logged to the master log file if the service cannot be started: SRVC STRT FAIL Could not find the domain controller for the domain When the Backup Server was installed, the option to authenticate through the Primary Domain Controller was selected. The Primary Domain Controller was not found for the domain specified during the installation. Verify that the correct domain name was specified. SRVC STRT FAIL The domain name could not be found When the Backup Server was installed, the option to authenticate through the Primary Domain Controller was selected. The domain name specified during the installation could not be found. Verify that the correct domain name was specified. SRVC STRT FAIL Connection to Backup Server port failed The Backup Server program could not connect to the Backup Server port specified in the configuration. Make sure that an unused port number was chosen. SRVC STRT FAIL Start of Backup Server listener failed The Backup Server program could not initiate listening on the Backup port. Verify the port number chosen. 28

System Errors ERRO "Security provider could not be initialized. Error: xxxxxxxxxxx This error indicates that security provider could not be initialized for the authentication type selected due to one of the following causes: The security DLL could not be loaded (Windows NT Authentication: security.dll; Membership Authentication: msapssps.dll) The security interface could not be initialized to allow access to the Security Service Provider The credentials handle could not be acquired in order to validate incoming authentication requests. Authentication Errors USER DENY username xx.xx.xx.xx The user name and password received from the client could not be validated This failure may be due to one of the following causes: User name doesn't exist in Windows User Accounts Database or Membership Directory Password is invalid Security provider was not initialized correctly License Errors ERRO Invalid license identification number If this error appears in the master log file, the Backup Server program found an inconsistency in your current licensing information. Disk Problems ERRO File exception occurred. Cause: Disk full One situation which may cause this error is that the Backup Server program could not process a client request due to an insufficient amount of disk space in the Work Directory specified in the configuration settings. Make more space available for the current work directory or reset the work directory to a new location. 29

Connection problems ERRO Connection failure This error appears in the master log file if the server cannot communicate with the client due to a broken connection. If the connection failed during a backup or restore operation, the processing will resume when the client re-connects to the server and continues from the point where the connection failed. ** WARNING: Disconnect or timeout received This message appears in the user log files when the Backup Server program receives a disconnect or timeout indication from the Backup Client. If this message appears at the end of the file after the backup or restore summary, then the disconnect is normal and does not indicate a problem. If it appears anywhere before this point, then the connection has been prematurely broken. The processing will resume when the client re-connects to the server and continues from the point where the connection failed. 30

Chapter 4: Using the Backup Server Configuration Manager Backup Server Configuration Manager The Backup Server Configuration Manager is used to add/delete/modify Backup Server users and to set other configuration parameters. It is also used to view and update current licensing information. See Figure 6. For a general overview, see section titled Configuration Overview. The OK Button This causes a new Backup Server configuration database to be written to disk, reflecting any updates that have been made. The Cancel Button This causes the Server Configuration Manager to exit without writing out a new configuration database, discarding any updates that have been made. The Apply Button This causes an updated configuration database to be written to disk, but does not exit the program. Figure 6 Backup Server Configuration Manager NOTES: If the Backup Server needs to be restarted because of a changed option, you will be notified with a message box. Otherwise, the Backup Server will update the changed information dynamically the next time the configuration information is read from the database. The frequency at which the configuration database is read and updated is determined by the settings on the General tab of the NovaNet-WEB Backup Server Configuration Manager. 31

Configuration Overview General After the Backup Server is installed, the installation directory will contain the file BackupServer.mdb. Each time the configuration database is updated, a duplicate copy of the file named BackupServerOld.mdb is written in the installation directory. This copy is used in the event that the current copy is deleted, corrupted, etc. The Backup Server Configuration Manager utility should be used to make all updates to the configuration database. Not only is it easy to use, but also, using the utility will ensure that the configuration database records are created and updated properly. By using the configuration utility, the chance of database corruption is greatly reduced. Comments The following comments refer to Backup Server configuration parameters: All parameters have default values with the exception of the license identification number and user account entries. When specifying user account information, at least one computer must be configured per account. The user data directory specified need not already exist. Configuration information is read initially when the Backup Server service is started. The license identification number, the maximum log size, the encryption setting and various other settings may be updated while the service is running. In addition, user accounts may be added/deleted or enabled/disabled. Other configuration settings can also be changed dynamically. The service will detect the changes the next time the configuration database is read. To modify all other parameters (including the user data directory specification for existing user accounts), the service must be stopped and restarted in order for the changes to take effect. User Accounts and Directories Before running the Backup Server, user accounts must be configured correctly through the User Manager to ensure successful user authentication. The user data directory is where all backup data (encrypted) resides for a particular user. This allows for more secure storage of data, as well as the ability to store data on remote systems connected to the network. One recommended way to set up user directories is to create a top-level user data directory and then specific subdirectories for individual user accounts. As a feature, when a new user is added, the application will automatically detect the most commonly used user data directory name already 32

configured for other users. It will set the default user data directory based on this path name and the new user name. In order to change the user data directory for a particular account, it is recommended that the service be stopped, the contents of the old directory moved to the new directory, and the service be restarted. 33

The Backup Server Database The Backup Server database (BackupServer.mdb) is a Microsoft Jet database that is used to maintain all server configuration information, as well as to optionally log all server transactions (i.e. backup/restore requests). If the additional transaction option is selected, the database will contain a copy of the pertinent information recorded in the user log files. This information is useful for billing, accounting, or reporting applications that may need an efficient way to retrieve information about individual transactions. NOTES: Even though the database holds the Backup Server configuration settings, all configuration information is still configured via the Backup Server Configuration Manager. If the additional option to have the server log transactions is selected, the Backup Server will still continue to generate user log files in the specified User Log directory. The following tables are maintained in the BackupServer.mdb file: Version Table The Version Table includes information about the current version of the Backup Server software. Directories Table The Directories Table includes information directory paths that are used by the Backup Server. Errors Table The Errors Table contains a list of error codes and descriptions that relate to error status codes that are recorded in the Requests Table. General Settings Table The General Settings Table includes miscellaneous configuration information for the Backup Server. This table includes the global quota settings and global blocked client options that may be in effect for user accounts. Notifications Table The Notifications Table identifies which types of notifications are configured and which error conditions result in notifications being sent. Requests Table (if transaction logging is turned on) The Requests Table includes information about each client request that is processed by the Backup Server. This table includes the type of request, the date of the request, the result status and relevant information pertaining to the particular type of request. 34

Users Table The Users Table includes information about each backup user that is configured. This table includes specific quota settings and blocked client options that may be customized for a particular user. Quota Settings Table The Quota Settings Table includes information about global quota settings that may be in effect for backup users. Quota Messages Table The Quota Messages Table includes information about specific quota message text that will be used in the event of quota conditions being met. Account Usage Table The Account Usage Table includes information about current disk space usage on the server for each backup user that is configured, as well as the total file selection size on the computer that originated the backup via the Backup Client program. 35

The Accounts Tab This window displays all of the configured users of Backup Server, including summary information about each user. See Figure 7. Summary Information Account Name This is the user account name that should match the user account name on the server system (configured through the User Manager). Computers This is the number of computers that will be backing up data to this user account. Clients backing up to this account must not exceed this limit or Backup Server will report an error back to the client. In this case, the number of computers would need to be increased before a successful upload for more computers could occur. Window Figure 7 Accounts Tab This field indicates the Previous restore window for the particular user account. This is the time interval (in weeks, days or months) where old versions of files will be saved on the server and will be available to restore on the client at a future point in time. Disk Usage This field indicates the current server disk usage for the particular user account. This information may also be viewed in relation to a possible quota limit established for the account. 36

The Add Button NovaNet-WEB Server The Add Button is used to add new Backup User accounts. Adding user accounts to the Backup Server allows a client to connect to a particular account to perform backup/restore operations. The Add Account window is used to add a new user account to the Backup Server configuration. For more information on individual account settings, see the section titled The User Account Properties Window. As a reminder, before running the Backup Server, user accounts must be configured correctly through the User Manager to ensure successful user authentication. One recommended way to set up user directories is to create a top-level user data directory, and then specific subdirectories for individual user accounts. As a feature, when adding a new user, the application will automatically detect the most commonly -used directory name already configured for other users. As a new user name is entered, the default directory will be set based on this path name and the new user name. The Remove Button The Remove Button is used to remove current Backup User accounts. Once a user is deleted, clients will no longer be able to connect to that account on the Backup Server. As an added option, the associated directories for that user can also be deleted. The Properties Button The Properties Button is used to display or update configuration parameters for a particular user account. This information includes the user name, number of computers, enable status, secure FTP home directory, user data directory and archive directory. The Properties window is used to display or update configuration parameters for a particular user account. This information includes the user name, number of computers, enable status, secure file transfer root directory, user data directory and archive directory. For more information on individual account settings, see the section titled The User Account Properties Window. 37

The Data Restore Wizard Button This Data Restore Wizard Button is used to run the Data Restore Wizard, which will prepare the data for a particular user account so that it can be easily restored by the user from local media (e.g. CD-ROM). The Global account settings Button The Global Account Settings Button is used to set certain options, such as client-blocking options and quota options that will be used globally for all Backup User accounts. In addition, these global options can be overridden or disabled completely for individual accounts. 38

The User Account Properties Window This window is used to add, modify, or view Backup User account information. The General Tab The following settings are included in the General Tab: Account Name Enabled Status Account Type Master Key Access Number of Computers Single/Multiple Computer Backup Option Restorable Window Account Data Directory Restore Wizard Button For more details on individual settings, see the section titled The Account Properties General Tab. The Block Tab The following list includes categories of client options that can be blocked: Functionality Backup Sets and Schedules Filters Tool and Toolbars General Backup Options Restore Options User Delete Capability For more details on individual settings, see the section titled The Account Properties Block Tab. 39

The Quota Tab The following settings are included in the Quota Tab: Account Quota Setting (Global/Custom/None) Account Quota Size Near Quota Percentage Near Quota Action At Quota Action Over Quota Percentage Over Quota Action For more details on individual settings, see the section titled The Account Properties Quota Tab. 40

The Account Properties General Tab This window is used to add, modify, or view the blocking options for a Backup User account. See Figure 8. Account Name This is the user account name that should match the user account name on the server system (configured through the User Manager). Enabled Status This checkbox indicates whether a particular user account is enabled or not. If the account is disabled, no backups or restores may be performed by a client connecting to the Backup Server until the account is enabled. Account Type This checkbox indicates whether a particular user account is an evaluation account or not. If this option is checked, it means that the account is being used on an evaluation basis. In this case, the client will only be able to access the account for a limited evaluation period before it times out. Figure 8 Account Properties Window If this checkbox was previously checked and then unchecked, indicating that the account has changed from an evaluation account to a normal account, the server will notify the client and the client will be automatically upgraded so that it doesn t time out. If this checkbox was previously unchecked and then checked, indicating that the account has changed from a normal account to an evaluation account, the server will notify the client and the client will be automatically downgraded so that it times out after a limited time period. 41

Master Key Access This checkbox indicates whether master key decryption is enabled or not. If master key decryption is enabled, then the data for this account may be recovered using the master key. To recover data, enter the master decryption key as the password in the Backup Client and connect to the particular user account. From the Restore Tab, the Get Volume List from Server and Get File List from Server options will display the volumes and files that are available for restoring. Number of Computers This is the number of computers that will be backing up data to this user account. Clients backing up to this account must not exceed this limit or the Backup Server will report an error back to the client. In this case, the number of computers would need to be increased before a successful upload for more computers could occur. At least one computer must be configured for each user. Single/Multiple Computer Backup Option The checkbox labeled Separate computers will be backing up to this account indicates that more than one physical computer will be backing up to the same account. This will prevent a backup on one computer from deleting volumes that were backed up by other computers. Typically, in the case of a single computer backup, the Backup Server would detect added and deleted volumes when a client backs up and make the necessary adjustments on the server. An example of this option would be backing up a desktop system and a laptop system to the same account. Restorable Window This is the time interval where previous versions of files that were backed up can still be recovered. The default is 1 month. If the capability for previous version restores is not desired for a particular account, this field can be set to 1 day. Account Data Directory This is the directory where all data for this user will be stored in an encrypted manner. This allows for more secure storage of data, as well as the ability to store data on remote systems connected to the network. 42

Restore Wizard Button This button will launch the Data Restore Wizard, which will prepare the data for the particular account so that it can be easily restored by the user from local media (e.g. CD-ROM). NOTE: When a new user is added, the Server Configuration Manager will automatically detect the most commonly configured path name already used for other accounts data directories. It will set the default account data directory name as the new account name appended to the detected path name. 43

The Account Properties Block Tab This window is used to add, modify, or view the blocking options for a Backup User account. See Figure 9. Account Blocking Setting There are three blocking options that can be set for a Backup User account. The account can use the global blocking settings, use custom blocking settings, or have no blocking options applied to it at all. If the custom blocking option is chosen, the following options can also be set. Options Available for Blocking Many options in the Backup Client software can be disabled for an individual user account by setting options on the server to block them. The options range from the ability to block basic backup/restore functionality to being able to block individual settings on the client. The following list includes the categories of options and individual settings (checkboxes) that can be blocked: Figure 9 Account Properties Block Tab Functionality Block the user from backing up Block the user from restoring Block changing to a different backup set Block file selections Block the user from deleting files on the server Backup Sets and Schedules Block the configuration of backup sets Block the configuration of schedules 44

The Account Properties Quota Tab This window is used to add, modify, or view the quota options for a Backup User account. See Figure 10. Account Quota Setting There are three quota options that can be set for a Backup User account. The account can use the global quota settings, use custom quota settings, or have no quota restrictions applied to it at all. If the custom quota option is chosen, the following options can also be set. Account Quota Size The account quota size is the quota limit (in megabytes) for the account. Near quota Options The Near quota options include the percentage of the quota limit at which a near quota condition will be detected and also the corresponding action to be taken by the Backup Client software. The default percentage is 90% and the default action is Report warning. This action will cause a warning to be generated in the client log. Figure 10 Account Properties Quota Tab At Quota Options The At quota options only include the corresponding action to be taken by the Backup Client software when an at quota condition is detected. The at quota percentage is always automatically set to 100% and the default action is Warning with window. This action will cause a separate warning window to be displayed in the client. 46

Over Quota Options The Over quota options include the percentage of the quota limit at which a near quota condition will be detected and also the corresponding action to be taken by the Backup Client software. The default percentage is 110% and the default action is Disable backup. This action will cause future backups to be disabled until the quota condition is alleviated. 47

The Global Account Settings Window This window is used to add, modify, or view global settings for Backup User accounts information. The Global Account Settings Window is displayed by pressing the Global Account Settings Button on the Accounts Tab. It is used to set certain options, such as client-blocking options and quota options that will be used globally for all Backup User accounts. In addition, these global options can be overridden or disabled completely for individual accounts.

Enable Global Quota Settings for Accounts Checkbox If this checkbox is checked, global quota settings will be in use. The following quota options will be available for setting. Account Quota Size The account quota size is the quota limit (in megabytes) for the account. Near quota Options The Near quota options include the percentage of the quota limit at which a near quota condition will be detected and also the corresponding action to be taken by the Backup Client software. The default percentage is 90% and the default action is Report warning. This action will cause a warning to be generated in the client log. Figure 12 Global Account Settings Quota Tab At Quota Options The At quota options only include the corresponding action to be taken by the Backup Client software when an at quota condition is detected. The at quota percentage is always automatically set to 100% and the default action is Warning with window. This action will cause a separate warning window to be displayed in the client. Over Quota Options The Over quota options include the percentage of the quota limit at which a over quota condition will be detected and also the corresponding action to be taken by the Backup Client software. The default percentage is 110% and the default action is Disable backup. This action will cause future backups to be disabled until the quota condition is alleviated. 52

Messages Button The Messages button is used to customize message text to be used in warnings issued by the Backup Client. Customized messages can be entered for each of the quota conditions ( near quota, at quota, over quota ), as well as for the individual quota actions. For more information, see the section titled The Global Quota Warning Messages Window. 53

The Global Quota Warning Messages Window This window is used to configure custom quota messages to be used by the Backup Client software when a quota condition is encountered. Text messages can be entered for each of the possible actions to be taken by the client ( Report warning, Warning with window, Disable backup ). The Backup Server transmits this information to the client when a quota condition is met. See Figure 13. The Warning Messages Tab Report Warning Text To change the default message for the Report warning action, enter a new text message. This text will be displayed in the client logs. Warning with Window Text To change the default message for the Warning with window action, enter a new text message. This text will be displayed in a separate warning window, as well as in the client logs. Disable Backup Text Figure 13 Global Quota Warning Messages Window To change the default message for the Disable backup action, enter a new text message. This text will be displayed in a separate warning window, as well as in the client logs. 54

The General Tab This window is used for general Backup Server Configuration parameters, including the Backup Server port number and the time interval between configuration updates. See Figure 14. Backup Server Port Set this to the port number that Backup Server will listen on for new connections. The default is port 308. Config Database Update Set this to the interval (in minutes) between times when the server will read the Backup Server configuration database to check if configuration parameters have changed. The value must be between 2 minutes and 1440 minutes (1 day). The default is 60 minutes. Configuration information is read initially when the Backup Server service is started. By specifying this time interval, certain configuration parameters may be changed without stopping the Backup Server service. The license identification number, the maximum log size, the encryption setting and Figure 14 - General Tab various other settings may be updated while the service is running. In addition, user accounts may be added/deleted or enabled/disabled. Other configuration settings can also be changed dynamically. The service will detect the changes the next time the configuration database is read. To modify all other parameters, the service must be stopped and restarted in order for the changes to take effect. In particular, if you wish to change the user data directory specification for an existing user, it is recommended that you stop the service, move the contents of the existing directory to the new directory, update the properties for that user, and restart the service. Duplicate Account Profiles Directory Set this to the top-level directory that will be used to store duplicate copies of user account profiles. These account profiles hold important information pertaining to particular user accounts and it is essential that the Backup Server have access to a valid user profile when processing a transaction for that user. Therefore, if a user profile becomes deleted, corrupt, etc., the Backup Server will have a duplicate copy to use. 55

The Security Tab This window is used for the Backup Server security options, such as how users will be authenticated and what type of encryption will be used. See Figure 15. User Authentication Set this to indicate which type of user authentication will be performed. Since the Backup Server is highly integrated with the NT security model, it can perform client authentication through the Windows NT/2000 User Accounts Database, a Microsoft Site Server Membership Directory or a standard LDAP database, including the Windows 2000 Active Directory. The Backup Server can authenticate users based on Username Only, Windows NT Local Authentication, Windows NT Domain Authentication, Membership Authentication (Clear-text/Basic), Membership Authentication (Challenge/Response) or LDAP authentication. The local and domain authentication options will authenticate users against the Windows NT User Accounts Database, while the membership authentication options will authenticate users against the Microsoft Site Server Membership Directory. The LDAP option will authenticate users against a standard LDAP database. The default value is "Use Windows NT domain authentication". Figure 15 Security Tab Use the Username only for Authentication This option will only authenticate client user names against the Backup Server configuration database (i.e. Backup Users configured through BackupServerUtil.exe). No password verification is performed in this mode. Use Windows NT Local Authentication This option will perform client authentication against the Windows NT User Accounts Database on the local server. This is achieved through Challenge/Response mechanism often referred to as NTLM (Windows NT Lan Manager) authentication. This type of authentication will attempt to use the current Windows logon credentials before requiring that a password be entered. Use Windows NT Domain Authentication This option will perform client authentication against the Windows NT User Accounts Database on the Primary Domain Controller. This is achieved through a Challenge/Response mechanism often 56

referred to as NTLM (Windows NT Lan Manager) authentication. This type of authentication will attempt to use the current Windows logon credentials for the domain before requiring that a password be entered. Use Membership Authentication (Clear-text/Basic) This option will perform client authentication against the Microsoft Site Server Membership Directory. In this authentication method, the client always sends the supplied credentials (user name and password) to the server. The credentials are always transmitted in an encrypted manner. This is the most common method used for authenticating users against the Membership Directory. Use Membership Authentication (Challenge/Response) This option will perform client authentication against the Microsoft Site Server Membership Directory. This is achieved through a Challenge/Response mechanism often referred to as DPA (Distributed Password Authentication). This type of authentication will attempt to use the current Windows logon credentials before requiring that a password be entered. Use LDAP Authentication This option will perform client authentication against a standard LDAP database. Also, specific credentials (username and password) must be set on the Backup Client for this authentication method. In other words, existing logon credentials cannot be used LDAP Settings Button If Use LDAP Authentication is selected, the LDAP Server must be configured. The LDAP server settings include the name or IP address of the server, the LDAP server port and the base distinguished name (DN) that users will be authenticated against. Also, if the LDAP directory is Windows 2000 Active Directory Services, then this must be indicated. 57

Enable Master Decryption Key This setting indicates whether or not a master decryption key is supported by the Backup Server system. The master decryption key allows for the capability to recover any user s data from the server if necessary. In addition, an individual user account must have the option set to allow data to be restored using the master decryption key. See the section on the User Properties window for more details. When this option is selected, the Master decryption key options button is highlighted. Press this button to complete the settings for this option. In order to be able to set or change the master key value, the password for the account under which the Backup Server is installed must be entered. The master key value can then be set or updated. If the master key is being changed, the old value must also be entered for security purposes. If this option was previously set and is no longer desired, simply uncheck the box. Backup Server Password For security reasons, the Backup Server logon password is required to set or update the master decryption key value. This is the same password that was entered when the Backup Server was installed under an account with Administrator privileges. Old Master Decryption Key For security reasons, the previous master decryption key value is required in order to update the master decryption key value. Master Decryption Key The master decryption key allows for the capability to recover any user s data from the server, if necessary. In addition, the individual user account must have the option set to allow data to be restored using the master decryption key. 58

The LDAP Server Window This window is used to configure an LDAP server for user authentication. LDAP authentication allows usernames and passwords to be authenticated against a standard LDAP database, including Windows 2000 Active Directory. Server Name or IP Address This is the name or IP address of the LDAP server where users will be authenticated against an LDAP database. "Windows 2000 Server with Active Directory Services" Checkbox When checked, this indicates that the LDAP database is Windows 2000 Active Directory. Port Number This is the port number of the LDAP server. The default LDAP port number is 389. Base Distinguished Name (DN) Figure 16 The LDAP Server Window This is the base distinguished name (DN) that usernames (i.e. UID attribute) will be searched against in the LDAP database. DN attributes must be separated by a comma (,) and can optionally contain a space following the comma. 59

The Directories Tab This window is used to specify the locations of miscellaneous directories. The first directory is the Upgrades directory, which will contain any Backup Client software upgrades that should be distributed by the Backup Server. The other directory is the Work directory, where temporary work areas will be located. See Figure 17. Backup Client Version Upgrades Upgrades Directory This is the directory where upgrades for the Backup Client software are placed. The Backup Server will then automatically distribute these upgrades to clients upon request. The name of the directory can be changed dynamically, which means that a new directory will take effect the next time the configuration database is read. The service does not have to be stopped. The default directory is "Install Directory \Upgrades. Work Directory Set this to the top-level work directory that will be used for backups and restores. Under the work directory, each thread connecting to a particular user account will create a unique temporary subdirectory. The Backup Server Figure 17 - Directories Tab requires this temporary work area in certain areas of processing. The space is freed when a backup or restore operation completes. There should be plenty of free disk space where the work directory is located. The following options are available: Use the account s data directory as the work directory This option causes the user data directory (configured for each user) to also serve as the temporary work directory used for all backups and restores to that user account. A subdirectory is created under the user data directory, which is the top-level directory for all work areas to be allocated for that particular user. This option is recommended if you wish to distribute where working areas are allocated. 60

Specify a work directory for all accounts NovaNet-WEB Server This option causes all temporary work areas to be allocated under one top-level work directory. Work areas for all configured Backup Users will be allocated under this directory. This option is recommended if you wish to have one global work directory for all users. It is especially important that plenty of free disk space be available in this case. 61

The Redundant Files Tab This window is used to specify the location of the file that contains the Redundant Files list. See Figure 18. Redundant File List This path contains the Redundant File List that will be used for each client. This file can be updated as more applications are added to the standard image. If the list has been updated, the Backup Server will then automatically send the updated list to clients when they connect. The name of the file can be changed dynamically, which means that a new file path will take effect the next time the configuration database is read. The service does not have to be stopped. There is no default location for this setting. If it is left blank, a redundant file list will not be used. The Run Redundant File List Manager Button The Run Redundant File List Manager button is displayed if no file path is currently specified for the Redundant File List. Pressing this button will cause the redundant file list utility to be run. The Redundant File List Manager is used to create a new file that will contain a Figure 18 Redundant Files Tab redundant file list. The list is a set of specific files, file names and file types that Backup Clients should exclude from being backed up, even if an individual user selects those files. The Properties Button The Properties button is displayed if a file path is currently specified for the Redundant File List. Pressing this button will cause the properties of the specified Redundant File List to be displayed. The properties include the specific files, file names and file types that are included in the Redundant File List. 62

The Logging Tab This window is used for configuration parameters related to logging. See Figure 19. Master Log The master log file (masterlog.txt) contains general information about the Backup Server service, as well as summary information pertaining to all client operations. Master Log File Directory Set this to the directory for the master log file. The default directory is the install directory. Master Log File Size Set this to be the maximum size (in bytes) for a log file. Once this size is reached, the current log file becomes archived and a new log file is created. The default size is 1024KB (1MB). Account Log Files User log files contain detailed information pertaining to individual client operations. Each user log file represents an individual client connection. Figure 19 - Logging Tab User Log File Directory Set this to the top-level directory that will hold user logs. A subdirectory is created under this directory for each user to hold individual log files. The default directory is "Install Directory"\Logs. Maximum Number of User Logs Set this to the number of user log files that should be saved for each user. Once this limit is reached, the Backup Server will automatically delete old log files. The default is 20 log files. 63

Database Logging In addition to account log files, all server transactions can also be recorded in the Backup Server database (BackupServer.mdb). The default is for database logging to be turned on. Log all server transactions to a database Check this box to allow server transaction information to be written to the database. The information is recorded in the Requests table in the Backup Server database. Database Tables Requests Table This table reflects all transactions that take place between clients and the server. Whenever the server receives a backup, restore or list request, the results are written to this table. This information includes the type of transaction, the date and time of the transactions, how much data was transmitted and the total time of the transaction. The outcome of the transaction (Success/Fail) is also recorded, as well as a specific error code if an error occurred during the transaction. The Requests Table includes a UserId field that relates to the Users Table and an ErrorId field that relates to the Errors Table. Errors Table This table includes a list of error codes and error descriptions. This table is used as a reference for errors that are reported in the Requests Table. 64

The Notifications Tab This window is used to specify which type of notifications, if any, should be issued in the case of an error condition. The default is for event logging to be turned on, and email and alert notifications to be turned off. All of the following information can be changed dynamically, which means that the new information will take effect the next time the configuration database is read. See Figure 20. E-Mail Check E-mail to allow e-mail recipients to be notified under specified error conditions. Check the attach user log file to mail message box if you wish to send the appropriate user log file with the e-mail notification. This option is only relevant for certain types of error conditions, such as exceptions, and some connection and authentication failures. Event Logs Check Event logs to allow error conditions to be written to the Windows NT application event log. Alerts Check Alerts to allow designated recipients to receive administrative alert messages for specified error conditions. Figure 20 Notifications Tab The Options Button The Options Button for each type of notification selected allows you to specify the error conditions that will cause notifications to be sent, as well as SMTP information for the E-mail option. See the sections titled The Notifications General Tab, The Notifications Error Conditions Tab and The Notifications Quota Tab. 65

The Notifications General Tab (E-Mail only) The Backup Server uses the industry mail standard, SMTP, to connect directly to an SMTP e-mail server and deliver e-mail notifications. This window allows you to configure the SMTP server and add e-mail addresses that will receive e-mail notifications. See Figure 21. SMTP Server Address This field indicates the address of the SMTP server where e-mail should be delivered. From Address This field indicates the e-mail address of the sender. To Addresses This field indicates one or more recipient e- mail addresses that should be included in the To field. Type the e-mail name of each recipient, separating names with a semicolon. Figure 21 Notifications General Tab Cc Addresses This field indicates one or more recipient e-mail addresses that should be included in the Cc (carbon copy) field. Type the e-mail name of each recipient, separating names with a semicolon. NOTES: 1. The application will attempt to resolve friendly names. 2. Since the Backup Server runs as a non-interactive process, it is important to realize that recipient addresses are present in the address book and that they are unambiguous. If an address cannot be resolved, it is skipped and a message will not be sent. 3. If there are one or more unresolved addresses in the recipient list, the Backup Server will still attempt to send e-mail notifications to those addresses that were resolved. 66

The Notifications Error Conditions Tab (E-Mail, Event Logs, Alerts) This window allows you to set various types of error conditions that will cause error notifications to be sent. See Figure 22. The following error conditions can be reported: Exceptions An exception indicates that the Backup Server generated an application error, such as a file exception or a memory exception. The type of exception will be reported, as well as the component it occurred in. NT System Errors A system error indicates that the Backup Server service could not be started due to a system error. The specific reason for the failure will be reported. Backup/Restore Errors Figure 22 Notifications Error Conditions Tab A backup or restore error indicates a Backup Server processing error. For example, an error could indicate that a file object was temporarily unavailable on the server. Connection Failures A connection failure indicates that a low-level connection between a Backup Client and the Backup Server was prematurely terminated or received an error. 67

Authentication Failures An authentication failure indicates that a user is not configured for the Backup Server, or that a user cannot be authenticated against the Windows NT User Accounts Database or the Membership Directory on the system specified. The specific user name that was denied will be reported. Low Disk Space Errors A low disk space error indicates that the Backup Server is running out of available disk space for account data. Licensing Warnings/Errors A licensing error indicates that the current license has expired or that the computer limit for the current license has been exceeded. The Set Default Button Pressing the Set Default Button will cause the utility to set default error conditions for the specific notification type. For Event Logs, the default is for all conditions to generate event logs. For E-mail and Alerts, the default is for exceptions and low disk errors to trigger error notifications. NOTE: As you move the mouse over the various error condition settings, notice that a text box is displayed at the bottom of the window, providing more information on each individual error category. 68

The Notifications Quota Tab (E-Mail, Event Logs, Alerts) This window allows you to set various types of quota conditions that will cause error notifications to be sent. See Figure 23. The following quota conditions can be reported: Account reaches Near quota % threshold If checked, this option will cause a notification to be generated when the near quota condition is encountered for a user account that has a quota limit enforced. The default near quota percentage is 90%. Account reaches At quota % threshold If checked, this option will cause a notification to be generated when the at Figure 23 - Notifications Quota Tab quota condition is encountered for a user account that has a quota limit enforced. The at quota percentage is always automatically set to 100%. Account reaches Over quota % threshold If checked, this option will cause a notification to be generated when the over quota condition is encountered for a user account that has a quota limit enforced. The default over quota percentage is 110%. 69

The Performance Tab This window is used to specify a pre-configured Performance Monitor setting to automatically select a grouping of specific Backup Server performance counters. See Figure 24. Performance Monitoring Monitoring Options The following list includes some of the preinstalled groupings: Active Snapshot %Processor Time, Active Backup Connections, Active Restore Connections, Bytes Total/Sec., Licenses in Use Client Upgrades %Processor Time, Total Upgrades Distributed, Active Connections, Configured Users Connectivity %Processor Time, Active Connections, Total Connection Attempts, Configured Users, Total Dropped Connections, Total Authentication Attempts Server Performance %Processor Time, Active Backup Connections, Bytes Sent/Sec., Bytes Received/Sec., Connection Attempts, FastBIT Applies/Sec. Figure 24 - Performance Tab Totals%Processor Time, Total Files Received, Total Files Sent, Total Backup Connections, Total Restore Connections NOTE: Some settings indicate heavy duty or light duty. This refers to the overall volume of activity on the particular server. For example, light duty would refer to a server with less than 100 users, where heavy duty would refer to a server with 100 to 10000 users. The performance counters are scaled appropriately based on what setting is chosen. 70

The Activate Button Pressing the Activate button will launch the NT Performance Monitor and display the selected group of Backup Server performance counters (e.g. Server Performance). See Figure 25. Figure 25 Performance Data 71

The Licensing Tab This window is used to view current licensing information or to update the License Identification Number. See Figure 26. Backup Server Licensing The following licensing information is displayed: Serial number This will display Unregistered Version or your product serial number if a valid serial number is entered. Current licensing mode This shows which license mode is active. It can be per seat or per time basis. This is determined by your license identification number and can only be changed with a new license identification number. Number of licenses/next timeout If licensing is on a per seat basis, the total number of licenses is displayed. If licensing is on a per time basis, the next expiration date is displayed. Licenses active /Usage identification If licensing is on a per seat basis, the current number of licenses which are active (configured) is displayed. If licensing is on a per time basis, the current range of use based on time is displayed. Also, a Usage Identification Number is displayed which NovaStor uses for billing the current usage cycle. Figure 26 Licensing Tab License Identification Number This number is the unique license number generated by NovaStor to identify a particular installation of the Backup Server. If a new license number has been obtained, enter it and press the Activate License button to update your current licensing information. 72

Chapter 5: Using the Redundant File List Manager Redundant File List Manager A new utility called the Redundant File List Manager has been added to the Backup Server. The Redundant File List Manager is used to build a set of specific files, file names, and file types that the Backup Client should exclude from backup, even if the user has those files selected. This feature allows server administrators to control the data that is backed up by their clients, especially when standard disk images are being used. The Redundant File List Manager can be executed directly from the Install Directory (Redundant File Manager.exe) or from the Backup Server Configuration Manager. The Redundant Files tab will display the Run Redundant File List Manager button if no file path is currently specified for the Redundant File List. Pressing this button will cause the redundant file list utility to be run. See Figure 27. The OK Button This causes a new redundant file list to be written to disk, reflecting any updates that have been made. The Cancel Button This causes the Redundant File List Manager to exit without writing out a new redundant file list, discarding any updates that have been made. Figure 27 Redundant File List Manager 75

The Apply Button This causes an updated redundant file list to be written to disk, but does not exit the program. The General Tab This window displays all of the redundant file entries for a particular redundant file list. See Figure 28. The Add Button The Add Button is used to add new redundant file entries. Each entry is used to add new exclusion rules to the current redundant file list (.rfl). Each entry can consist of any or all of three different types of exclusion rules. The Add Redundant File Entry window is used to add a new redundant file entry to the current redundant file list. A redundant file entry consists of a symbolic name and a set of exclusion rules. A particular redundant file list can consist of one or more redundant file entries. This capability allows sets of files, file types etc. to be grouped logically and offers greater flexibility when it comes to modifying a redundant file list. The Remove Button The Remove Button is used to remove current redundant file entries. Once an entry is deleted, its exclusion rules will no longer be included in the redundant file list. Figure 28 General Tab The Properties Button The Properties Button is used to display or update specific exclusion rules for a particular redundant file entry. 76

The Redundant File Entry Properties Window This window is used to add, modify, or view details of a particular redundant file entry in the current redundant file list. The Redundant File Entry Properties window consists of the following tabs: The Name Tab The Specific Files Tab The File Names Tab The File Types Tab The Name Tab This window is used to add, modify or view the name of the current redundant file entry. See Figure 29. Redundant File Entry Name This is the symbolic name of the redundant file entry. It should describe the type or category of the files that are being excluded in this entry. Figure 29 Properties/Name Tab 77

The Specific Files Tab This window is used to add, modify, or view the specific files included in the current redundant file entry. A file selected in this window will only be excluded from a backup only if there is an exact match against the CRC and size of the file. See Figure 30. Note: This window supports the dragging and dropping of files and folders from Explorer as an easy way to add files and/or entire directories. The Add File Button This button allows individual files to be browsed and selected for the redundant file entry. The Add Folder Button This button allows individual folders to be browsed and selected for the redundant file entry. The Scan Entire Subtree Checkbox This checkbox allows the all of the files in the subtree of a selected folder to be added to the redundant file entry.

Chapter 6: Using the Data Restore Wizard The Data Restore Wizard is started by pressing the Restore Wizard button on the User Account Properties General Tab. The wizard is used to prepare data for the particular account so that it can be easily restored by the user from local media (e.g. CD-ROM). Creating Restorable Media Sets Step 1 - Introduction The Data Restore Wizard is used to create restorable media sets that can be written to CD-ROMs or other media. In order to restore the data contained on the media, a Restore-only backup client program is included on the media. The Data Restore Wizard will prompt you for the following information to create the locally restorable files: The account name for which the data will be prepared The computer name and volume name(s) to be used for the account The maximum media size for the destination media The root directory where the prepared account data will be written Information to be placed in the Restore-only client s About Box The language to use when running the Restore-only client Once the above information has been entered and verified, the account data will be prepared. The data is then ready to be transferred to the final media. Data Restore Wizard - Introduction 83

Step 2 - Select User Account Available accounts This listbox displays all of the available user accounts, including the account names and current server disk usage for each account. In addition, the total number of currently configured user accounts is displayed. Data Restore Wizard Select User Account Step 3 - Select Data Volumes Available volumes This listbox displays all of the available data volumes for the user account that was selected. The list includes the volume names, the number of files contained within each volume and the total size of the volume. In addition, the total number of volumes available and the total number of volumes selected are displayed. Data Restore Wizard Select Data Volumes 84

Step 4 - Select Media Size Disk space requirements The following information is based on the disk space required and the data volumes selected: Space required on each media This is the amount of space that is required on the media for files other than the actual data. These additional files are contained in the Data Restore Wizard Files subdirectory under the Install directory. If it is desirable to have any other files (e.g. Readme, HTML files) automatically included on the final media, they can also be added to this subdirectory. Data Restore Wizard Select Media Size Account data size This is the actual data size for the volume(s) selected. Largest single file This is the size of the largest file for the volume(s) selected. Common media sizes This listbox displays common media types and their sizes. If a common media size is desired, select a type and size from the drop-down list of commom media types. Custom media sizes This listbox allows specific media sizes to be entered (in kilobytes, megabytes or gigabytes). If a custom media size is desired, enter a specific size in the fields provided. 85

Media requirements The following information is based on the media size selected: Number of media required This is total number of media required based on the selected media size. Oversized files that will be skipped This is the number of files that cannot be placed in the media set because the sizes of the files are too large to fit in the selected media size once the required files are written. Required disk space This is total required disk space needed to write the account data plus the additional space required on each media. Required disk space = ( Number of media required * Space required on each media ) + Account data size 86

Step 5 - Select Root Directory Disk space requirements The following information is based on the disk space required and media size selected: Required number of media This is total number of media required based on the selected media size. Required disk space This is total required disk space needed to write the account data plus the additional space required on each media. Required disk space = ( Number of media required * Space required on each media ) + Account data size Data Restore Wizard Select Root Directory Media root directory This field is the destination directory where the restorable media set will be built. The drive containing this directory must have enough space to hold the Required disk space amount described in the above section. The Browse button ( ) can also be used to select the root directory. Ask to delete all files and folders in the destination directory checkbox If this checkbox is checked, a prompt will be issued to delete all files or folders that already exist in the root directory. If the answer is Yes, all files and folders in the root directory will be deleted prior to preparing the current restorable media set. If this checkbox is not checked, any files or folders that are present in the destination directory will remain in the directory, and the current restorable media set will be added to the directory. 87

Step 6 - Other Options Language Select the language that should be used when running the Setup program for the Restoreonly client software. The following languages are supported: English German Data Restore Wizard Other Options Step 7 - About Box Information Support Information It is possible to customize the information contained in the About Box of the Restoreonly client software.
