Acknowledgements: Two encryption methods, DES and TripleDES, include cryptographic software written by Eric Young. The Windows versions of these algorithms also include software written by Tim Hudson. Bruce Schneier designed Blowfish encryption. The EVault InfoStage Agent, EVault InfoStage CentralControl, and EVault InfoStage Director applications (version 4.x only) now have the added encryption option of 128bit AES (Advanced Encryption Standard). Advanced Encryption Standard algorithm (named Rijndael, pronounced Rain Doll ) was developed by cryptographers Dr. Joan Daemen and Dr. Vincent Rijmen. This algorithm was chosen by the National Institute of Standards and Technology (NIST) of the U.S. Department of Commerce to be the new Federal Information Processing Standard (FIPS). AES is not available when connecting to a Vault lower than version 4.1. See: for details. The EVault InfoStage Agent and EVault InfoStage Director applications (version 4.x only) also have the added security feature of an over the wire encryption method for data communications developed exclusively by EVault, Inc. This is not a selectable option (always on) and runs silently to the user. Over the wire encryption is not available when connecting to a Vault lower than version 4.x.

4 1 MS SQL Server Plug-In 1.1 Overview The EVault InfoStage MS SQL Server Plug-In has been designed to allow a user to perform a database backup (and subsequent restore, if necessary) on an MS SQL Server. The Plug-In is installed on top of the EVault InfoStage Agent on the database host, to perform the backups, either on demand, or scheduled. The EVault InfoStage CentralControl application has been modified in this version to accommodate the functions and inputs necessary for this plug-in. Configures DB Backup and Restore Host (User) CentralControl User Configures Host (DB Server) Agent, with SQLServer Plug-In LAN / WAN Host (Vault) Director Database(s) Figure 1 This diagram illustrates the basic product implementation. A user, typically a DBA, will configure the backup via the CentralControl application. CentralControl configures the agent, which may reside on a different host than CentralControl. However, the Agent and Plug-In must reside together on the MS SQL Server system. The User may schedule a backup of the Database, at which time the agent, with the aid of the DB plug-in, sends the database information to the Director. MS SQL Server Plug-in Page 4 of 17

5 1.2 Features The Plug-In application has its own installation program, but is operated and configured within the CentralControl (CC) program GUI MS SQL Server 7 or 2000, running on Windows 2000 Server, or Advanced Server (SP3) The database(s) to be backed up must run on a single host. The Windows Agent and the MS SQL Server Plug-In must be together on the same system running MS SQL Server. The Windows Agent and the MS SQL Server Plug-In must always have the same version number. If a database host is completely lost, the database software may be loaded and the database completely restored, after a full system restore Hot backup - occurs without taking the database down Restore may be to same or alternate database location, or to a flat file Provides full and incremental backup MS SQL Server 7.0 supports one (default) instance (i.e.: "computer_name"). MS SQL Server 2000 supports a default instance, and up to 15 Named instances (i.e.: "computer_name\instance_name") The Plug-In will: Dynamically determine what SQLServer client is installed. If it is SQLServer 7 client, the Plug-In will support access to the single instance of SQLServer 7 installed (if it exists). If it is SQLServer 2000 client, the Plug-In will support access to all instances of the server installed (regardless of what version they are). Version 4.20 of the MS SQL Server Plug-In is implemented using the Microsoft-defined Virtual Backup Device Interface (VDI). This interface is a high-performance alternative to Named Pipes that was used in the implementation of Version 4.10 of the MS SQL Server Plug-In. MS SQL Server Plug-in Page 5 of 17

10 2 Installing the MS SQL Server Plug-In The MS SQL Server Plug-In integrates into the existing InfoStage architecture and provides the user with the ability to backup/restore MS SQL Server database to/from the Director. Installing the EVault InfoStage MS SQL Server Plug-In version 4.20 requires that you have previously installed the EVault InfoStage Windows Agent application, version If your EVault CentralControl application version is lower than 4.2, you must update it to version 4.20 before installing the MS SQL Server Plug-in. Also, your Director must be running EVault InfoStage Director version 4.20 to use the MS SQL Server Plug-in. To install the MS SQL Server Plug-In double click on the MS SQL Server-Plug-In file ( MS_SQL_Plugin.exe) or use the Windows Start, Run sequence locating the path to the MS SQL Server Plug-In application. This will launch the install wizard. Follow the detailed steps outlined in the installation Wizard. If the SQL Server being backed up by the Plug-In was not installed as an original Microsoft product (that is, it has been resold/repackaged by a third party), you may get errors on trying to create an MS SQL task, such as Failed to connect to the server. Agent log may show UNKNOWN ERROR in termrestore() on every attempt to connect to the SQL Server. Get Status on the Agent may not show the SQL Server Plug-in, even though the license validates. The problem is that the installation is missing the NTWDBLIB.DLL file, which should be in the EVault installation directory. Contact support to obtain a copy of this file. Note: For functions such as Creating a new agent, Creating a backup task, Scheduling Backups, and Disaster Recovery information, refer to the EVault Installation and User Guides for more information on installing and using the EVault software. 2.1 Licensing Agent License info: After installing the MS SQL Server Plug-In, you must supply license information before you can use the Plug-In. 1. Obtain a license from EVault, or your service provider. 2. On the CentralControl program, under My Agent, -> Global Settings -> License (tab) enter the license information. 3. Press Test, to ensure the license is correct/valid. If not, renter the data. 4. Press Set to save the information. 5. From the CentralControl program, if you create a new task, you should now be able to see MS SQL Server under Backup Source Type. Installing MS SQL Server Plug-In Page 10 of 17

11 3 Backups 3.1 Table for User Backup Information Before performing the MS SQL Server database Backup process, be sure you have all the information such as names, locations, passwords, etc. that the Wizard will prompt for. The table below is provided for reference. System Requirement Customer/User supplied value Comments New task name Name = Task used to talk to the agent with MS SQL Server Plug-In Vault profile Profile = Profile of an existing (already created) Vault. Chosen from a pull-down menu. Backup Source type Type = Select MS SQL Server from the pull-down menu. MS SQL Server Connection Information MS SQL Server database selection Backup types Computer = Instance = Authentication = NT or SQL User Name = Password = Database = Dependent on user s configuration and DBA setup. Validates the fields, and allows access to the database. Pull-down list of all available databases. Choose Full or Incremental Network Account Information User Name = Password = Domain = Quick file scanning Encryption type Type = Password = Log options Options = Detail level = Copies = Start the backup Immediate = Schedule = Supplies NT credentials to the server. Enables backup process to run across the network. Set on or off If you select a type, you must supply a password User defined Uses the Scheduling Wizard Backups Page 11 of 17

12 3.2 Performing Backups To back up your MS SQL Server you will first need to add the Agent with the MS SQL Server on it to your workspace, and then create a new task in that agent, using MS SQL Server type. It is not recommended to do multiple tasks, at the same time, on the same database. The Backup Wizard will direct the user through the process to create a task, but briefly, the steps to perform this include: 1. From the CentralControl GUI program (which communicates with the agent and the plug-in), create a new task. 2. Enter a Vault profile where the task will be targeted. 3. Select the source of the data that will be backed up by this task. 4. Supply the MS SQL Server connection information. Enter the MS SQL Server computer name. Then choose an instance from the Select Server Instance list. The list will have the first entry pre-selected as <Default>, designating the default instance. Other entries will be present only if they can be retrieved. Next, choose the NT or SQL authorization option. (See the MS SQL Server Help section on NT/SQL Authorization for more information.) - If you choose the NT authorization button, access is by the NT logon supplied user name and password. User Name and Password on this screen are not used. - If you choose the SQL authorization button, access is determined by the User Name and Password on this screen. 5. Select a specific database for backup. Only one database at a time is backed up with each task. But there can be more than one task doing backups, on different databases. 6. Enter network account information to enable the backup process to run across the network User name, password, and domain. This allows the Agent to connect to a local or remote database. 7. Select or de-select the Quick file scanning option. Note that the deferred option is not available here; the backup must be completed in one step. 8. If desired, select an encryption type and supply an encryption password. 9. Select logging options and level of detail, copies, and retention. 10. Start the backup (immediately), schedule it for later, or exit the Wizard. Log files are created on the CentralControl machine, under the EVault directory, in directories with the task name. They are normally viewed from the CentralControl application screen. Note: On the Backup Wizard By Type, you will be shown disabled Backup type choices of Full, Incremental or Differential Backup. They are disabled here because it is an MS SQLServer database backup. But, on the Backup Wizard Options screen, under MS SQL Server Database options, you may choose a backup type of Full or Incremental. Backups Page 12 of 17

13 Backup Notes: 1. MS SQL Server 7.0 does not allow incremental backups for databases with the trunc.log on chkpt options. Likewise, MS SQL Server 2000 doesn t allow incremental backups for databases if the model of database is set to Simple. 2. MS SQL Server 7.0 does not allow incremental backups for databases after switching the trunc.log on chkpt options off (or truncating log) until at least one successful full backup. Likewise, MS SQL Server 2000 does not allow incremental backups for databases if the recovery model of database is set to Simple. 3. MS SQL Server Plug-In has standard backup/restore permission requirements for the logged user: 4. Backup Permissions: BACKUP DATABASE and BACKUP LOG permissions default to members of the db_owner fixed database role, who can transfer permissions to other users, and to members of the db_backupoperator fixed database role. Backups Page 13 of 17

14 3.3 Backup Wizard This section describes the new screens in the Backup Wizard that do the SQL Server connection: Computer selection, Instance selection, and Authentication. Computer Selection: Task Wizard - MS SQLServer Enter Computer name Computer: < Back Next > Cancel This allows the user to enter a computer name. The Next button is disabled until something is entered. There is no connection/verification here. That comes after the Authentication screen. Instance Selection Task Wizard - MS SQLServer Select Server instance Available instances: <Default> Instance1 Another Instance < Back Next > Cancel This presents a list of the SQLServer instances available for the client installed. The list will always include as first and pre-selected an entry named <Default>, designating the default instance. Other entries will be present only if they can be retrieved. The user will select an instance and proceed to the next screen. Backups Page 14 of 17

15 Authentication Task Wizard - MS SQLServer Enter Authentication information Computer: Instance: NT Authentication SQL Server Authentication User Name: Password: Confirm Password: < Back Next > Cancel The screen will allow the user to select the authentication type (NT or SQL) and enter a user name and password to connect to the selected instance. After entering valid credentials, the user will proceed to the database selection dialog, which is the same as before. Note here that Computer and Instance names are presented in read-only format, for information purposes. The SQL Server Authentication option can only be chosen if SQL Server and Windows authentication is enabled on the SQL Server. 3.4 Task Properties This section describes a new tab in the screen for displaying/changing task properties, for all versions of the plug-in. Task properties SQL Server Source Computer: Instance: Authentication User Name: Database: Change... OK Cancel In the Task Properties, the SQL Server Source tab will display: Computer name or address Instance name or <Default> Authentication type (NT or SQL Server) User name Database name Backups Page 15 of 17

16 The Change button will bring up a Wizard (similar to Backup) consisting of: Computer Selection screen Instance Selection Screen (this will be skipped for previous version of the plug-in) Authentication Screen Database Selection Screen Finish screen 3.5 Error Messages When an SQL database is backed up using the incremental (transaction log) method, the logs are sent to the Vault, and are applied against the last full backup, when doing a restore. However if another user or task, outside of the EVault applications, causes the database to produce a transaction log file, it is recorded by the SQL server, in msdb, but EVault does not know about this. In this case the transaction log files are out of synch, for EVault, and thus the system must create a full backup to ensure integrity of the data, as one or more of the transaction log files is missing from the EVault backup. The backup process detects that the logs are out of synch and automatically switches from an incremental backup to a full back. No action is required on the part of the user/dba. An informational message is written to the backup log (history) file. (Note that the backup process may take longer than anticipated, as the process is now a full backup, as opposed to an incremental one.) An external backup was detected. Switching from Incremental to Full backup. This means that the backup history of the database in the system SQL database msdb is out of synch with the list of successful task backups on EVault server. List of possible reasons: - The database backup was made outside the selected task after last successful task backup - Some files were lost on EVault server - Backup history was cleaned up - msdb was restored As well, on a restore, the system may discover that the transaction log files are out of synch, and again will switch to a full backup. Again, no action is required on the part of the user/dba. An informational message is written to the backup log (history) file. A compromising restore was detected. Switching from Incremental to Full backup. This means that the restore history of the database in the system SQL database msdb indicates that the database was restored after the last successful full backup in this task. List of possible reasons: - The database was restored after last incremental backup in this task - Backup/restore history was cleaned up - msdb was restored Backups Page 16 of 17

17 4 Restores For Restore, the user will specify a backup (a particular safeset) up to which he would like to restore. Restores can be to the original location, an alternate location, or a file. Restores may be necessary in three scenarios: Restoring the full database, with any incremental backups, overwriting the existing database. With no system backup, restoring the system from the ground up ( bare metal ) installing the OS, applications and then the full database, and any incremental backups, onto a new system. If there is an MS SQL Server backup, and a full system backup, install the OS and then restore the system, and MS SQL Server. The Restore Wizard will direct the user through the process, but briefly, the steps to perform this include: 1. From the CentralControl, select the restore function (Wizard). 2. Supply the restore type location and type Vault and safeset 3. Confirm account information for MS SQL Server authentication computer name, instance selection, user name, and password. Choose the NT or SQL authorization option. 4. Select the destination where the MS SQL Server database should be restored original database, other database, or Directory. 5. Enter network account information that will enable the restore process to run User name, password and domain. 6. Select logging options and level of detail. 7. Start the restore process. Restore Notes: 1. Restore Permissions: If the database being restored does not exist, the user must have CREATE DATABASE permissions. If the database does exist, RESTORE permissions default to members of the sysadmin fixed server role and the db_owner fixed database role. 2. REPLACE option specifies that MS SQL Server should create the specified database and its related files even if another database already exists with the same name. In such a case, the existing database is deleted. When the REPLACE option is not specified, a safety check occurs (which prevents overwriting a different database by accident). The safety check ensures that the RESTORE operation will not restore the database to the current server if: The database named in the RESTORE statement already exists on the current server, or Either the database name is different from the database name recorded in the backup set, or The set of files in the database is different from the set of database files contained in the backup set. Differences in file size are ignored. Restores Page 17 of 17
