Backup-Error message when you try to perform a system state backup in Windows Server 2008: "ERROR - The location for backup is a critical volume"

Reason: This behavior occurs because system state backups to critical volumes are blocked in Windows Server 2008.

Solution: We can change the default behavior of Windows Server 2008 by adding a registry entry.

Registry entry to enable system state backups to critical volumes

Warning: Serious problems might occur if you modify the registry incorrectly by using Registry Editor. So be ensure to have a backup of registry before make any change in it.
To enable the system state backup files to be targeted to critical volumes, We must set the value of the AllowSSBToAnyVolume registry entry under the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wbengine\SystemStateBackup\

 

Set the value of this entry as follows:

Name: AllowSSBToAnyVolume
Data type: DWORD
Value data: 1

Note: When this value is set to 1, system state backups to any volume are enabled. To revert to the default behavior, set the value to 0.
