4 Creating a Windows Server Backup image for system disaster recovery Creating a Windows Server Backup image for system disaster recovery A backup image for system disaster recovery can be created through the WSB command line tool wbadmin.exe or the WSB wizard. NOTE: Microsoft documentation provides more details on using WSB. The Windows Server Backup can be stored on either a local volume or a remote shared folder. Note the following considerations: Local volume considerations The following lists considerations for local volumes: The volume cannot be a critical volume and cannot be included in the backup. A critical volume is defined as any volume that has System States, or any part of them, installed, as well as any volume that has Windows services installed. Identify an account that is a member of the Administrators or Backup Operators group for the backup computer. It is recommended that the volume is dedicated to the snapshot, or backup performance might be severely degraded. The local volume must be NTFS formatted. Do not store backups on USB flash or pen drives. Multiple versions of the backups will be stored on the local volume, depending on the size of drive. Remote shared folder considerations The following lists remote shared folder considerations: Backups are overwritten each time there is a new backup. Identify an account that is a member of the Administrators or Backup Operators group for the backup computer, and has write access to the remote shared folder. The server with the shared folder must be in the same domain as the NetWorker client. If a remote share will be used to backup the WSB image and this share is on a Windows 2003 server: 1. In Windows Explorer on the computer with the local share, right-click the folder, and select Share. 2. In Sharing, enable Share this folder and click Permissions. 3. Click Add. 4. In the Select Users, Computers or Groups windows, click Object Types. 5. In the Object Types window, select Computers to include entries in the search.

Type the name of the NetWorker client that will backup the WSB client in the Enter the object names to select field. 8. Click Check Names. 9. Click Ok. 10. In the list of accounts with access to the share, click the newly added account, and set the permission level to Contributor. 11. Click Share. If a remote share will be used to backup the WSB image and this share is on a Windows 2008 server: 1. In Windows Explorer on the local share, right-click the folder, and select Share. 2. Select Find from the drop down menu in the Choose people on your network to share with window. 3. Click Customize on the left of the window. 4. In Enter the object names to select, type a user account which is a member of the Administrator group on the NetWorker client. This user account is what will be used to create the WSB backup. NOTE: On the NetWorker client, the account for backups must be a member of the Administrator group. 5. Click Check Names. 6. Click Ok. 7. In the list of accounts with access to the share, click the newly added account, and set the permission level to Contributor. 8. Click Share. Creating a Windows Server Backup image from the command line (for client-initiated manual backups) You can create a backup image from the command prompt using either a local drive or a UNC format remote drive. In both cases, the volume must have enough disk space for the sum of all the space used on the critical volumes. If a remote drive is used, you must supply the username and password at the command line. Creating a backup image on a local drive from the command line To create a backup image from the command line, type the following command: wbadmin start backup -backuptarget:<drive letter> -allcritical -quiet For example: wbadmin start backup -backuptarget:e: -allcritical -quiet WINDOWS SERVER 2008 OFFLINE SYSTEM RECOVERY USING WINDOWS SERVER BACKUP WITH NET- 5

9 Backing up the WSB image to a NetWorker Server Backing up the WSB image to a NetWorker Server This section describes two different options for backing up a WSB image to a NetWorker server: Manually backing up the WSB backup image to a NetWorker server. Automating the WSB image creation and configuring backup to a NetWorker server. Preparing a Windows 2008 client for NetWorker Backup Perform the following tasks before a manual or automatic WSB backup to a NetWorker server. Create a precmd script file to launch the WSB backup When the NetWorker server launches the backup of the Windows 2008 client for offline backups, a savepnpc.exe file is executed on the client to create the WSB backup. The WSB backup is then backed up by the NetWorker server. First, create a PRECMD script file to launch the WSB backup: 1. Create a new file on the Windows 2008 client using notepad. 2. Add the following lines to the file: echo "Start WSB Backup of Critical Volumes" >> WSBCreateBackup.log time /t >> WSBCreateBackup.log date /t >> WSBCreateBackup.log wbadmin start backup -backuptarget:\\<servername>\<sharename> - allcritical -quiet echo "Complete WSB Backup of Critical Volumes" >> WSBCreateBackup.log time /t >> WSBCreateBackup.log date /t >> WSBCreateBackup.log where <servername> is the name of the server on which the remote share resides, and <sharename> is the remote share name. 3. Save this file as precmd.bat in a new directory that does not contain spaces (for example, C:\Scripts). Create a postcmd script file to remove the WSB image after backup 1. Create a new file on the Windows 2008 client using notepad to specify a command which will remove all files in the directory/share after NetWorker has backed up the image backup. For example: rmdir /S /Q :\\<servername>\<sharename>\windowsimagebackup where <servername> is the name of the server with the WSB backup and <sharename> is the name of the share containing the WSB image backup WINDOWS SERVER 2008 OFFLINE SYSTEM RECOVERY USING WINDOWS SERVER BACKUP WITH NET- 9

10 2. Save this file as postcmd.bat in C:\Scripts Backing up the WSB image to a NetWorker Server Create a savepnpc script file to execute the WSB backup 1. Create a new file on the Windows 2008 client using notepad. 2. Add the following lines to the file: type: savepnpc; precmd: "C:\\Scripts\\precmd.bat"; pstcmd: "C:\\Scripts\\postcmd.bat"; NOTE: More details regarding the use of savepnpc script files are provided in the NetWorker Administration Guide. 3. Save the savepnpc script file in C:\Program Files\Legato\nsr\res as groupname.res, where groupname is the name of the NetWorker backup group to which this client belongs. Providing permissions to backup to a remote device To provide the NetWorker Remote Exec service with permissions to backup to a remote device: 1. In the Windows 2008 client Control Panel, click Services, right-click on NetWorker Remote Exec, and select Properties. 2. Click the Log On tab, and enable This Account. 3. Click Browse, and type a local account name which is an administrator and has write access to the remote share. Click Check Name. 4. Click Ok. 5. Type the password for the account and click Ok. 6. Stop the NetWorker Remote Exec service, then restart the service. Manually backing up the WSB backup image to a NetWorker server To manually back up the WSB backup image to a NetWorker server: 1. Install the NetWorker client on the host machine where the WSB image is located. 2. Configure the client on a NetWorker server. 3. On the host machine where the WSB image is located, start the NetWorker User program by selecting Start > Run and typing winworkr. 4. In the NetWorker User program, click the Backup button. 5. Select the volume containing the WSB image for backup. 6. Click the Start button. 7. When the backup completes, close the NetWorker User program.
