Creating a Windows Server Backup image for system disaster recovery


Creating a Windows Server Backup image for systemdisaster recovery

A backup image for system disaster recovery can be created through the WSBcommand line tool wbadmin.exe or the WSB wizard.

Creating a Windows Server Backup image from the commandlineYou can create a backup image from the command prompt using either a localdrive or a UNC format remote drive. In both cases, the volume must have enoughdisk space for the sum of all the space used on the critical volumes. If a remotedrive is used, you must supply the username and password at the command line.

Creating a backup image on a local drive from the command lineTo create a backup image from the command line, type the following command:

wbadmin start backup -backupTarget: -allCritical -quiet

For example:

wbadmin start backup -backupTarget:E: -allCritical -quiet

N O TE: < d r i v e l e t t e r > cannot be a locally-mapped networkshare. - a l l Cr i t i c a l instructs the vbadmin.exe command toback up all critical volumes of the system. A critical volumeis defined as any volume that has System States, or any partof them, installed, as well as any volume that has Windowsservices installed. - q u i e t is required to run in non-interac-

tive mode.

Creating a backup image on a remote shared folder from the command lineTo create a backup image from the command line, type the following command:

wbadmin start backup -backupTarget: -allCritical-user: -password: -quiet

For example:

wbadmin start backup -backupTarget:\\10.0.0.1\WSBShare-allCritical -user:administrator -password:password -quiet

N OT E: < t a r g e t n a m e > cannot be a locally-mapped net-work share. - a l l Cr i t i c a l instructs the vbadmin.exe commandto back up all critical volumes of the system. A critical vol-ume is defined as any volume that has System States, orany part of them, installed, as well as any volume that hasWindows services installed. - q u i e t is required to run in non-interactive mode.

with the desired client in the left tree pane, then select the appropriateclient in the list on the right. Click Fin i sh to create the new group.

NOTE: To use an Avamar scheduled backup, it is importantthat the WSB backup is also scheduled such that it com-pletes before the start time of the Avamar scheduledbackup. It may be difficult to synchronize these two events,because the WSB backup time can vary greatly. In thosecases, automate the WSB image creation and Avamarbackup as described in Automating the WSB image creation and backup t o an Avamar server (page 13) .


13/21



Automating the WSB image creation and backup to an AvamarserverIn order to perform automated WSB image creation and backup to an Avamarserver, the following configuration details must be observed:

The Avamar client must reside on the Windows Server 2008 machine. A remote machine must contain a shared folder which will be used by wbadmin

as the target location for the WSB image file. The Avamar dataset must include the UNC path for this share as the location of

the data to backup.

NOTE: The use of a UNC path in the dataset to specify thelocation of the remote WSB image to backup is only sup-ported in the Avamar 4.1 and 5.0 clients. It is not supportedin Avamar 4.1 Service Pack 1 clients.

To automate the WSB image creation and backup to an Avamar server:

1. Create a script in C:\Program Files\avs\etc\scripts with an extension of .bat, .vbs or .js that calls the wbadmin.exe program, using the commandline described in Creating a Windows Server Backup image from the command line (page 4) .

2. Create a script in C:\Program Files\avs\etc\scripts that deletes the WSBimages.

If the WSB image is created on a network share, deleting theWindowsImageBackup folder will be sufficient. However, if the WSB iscreated on a local drive of the source client, the VSS snapshots may alsoneed to be deleted. Tools such as vshadow or diskshadow can be used inaddition to wbadmin.


4. Activate the client with an Avamar server.

5. Start the Avamar Administrator and click on Ba ck u p a n d Re st o r e to startthe console.

6. Select Ma n a g e Da t a s e t s from the To o l s menu.

7. Select the appropriate domain in the tree and click N ew .

location of the network share where the WSB image will be created.

(d) Click the + button to commit this path to the dataset.

(e) Click OK to close the Select Files and/or Folders dialog.

(f) Click OK again to close the New Dataset dialog.

9. Follow steps 7 and 8 from Scheduling a backup of the WSB backup image to an Avamar server (page 8) to create a schedule and group that use thisdataset.
