How To Allow System State Backups To Critical Volumes In Windows Server 2008?

This article explains a registry hack you can use to allow System State to be backed up to a critical volume in Windows Server 2008.

When you try to backup the System State backup on a critical volume on a computer running Windows Server 2008, you will get the error message. This is because of the default behavior of Windows Server 2008. It doesn't allow you to take backup of System State data on a "Critical Volume".

You can change this behavior by hacking the following registry entry:

  • KEY_NAME: HKLM\SYSTEM\CurrentControlSet\Services\wbengine\SystemStateBackup
  • ENTRY_NAME: AllowSSBToAnyVolume
  • VALUE:  (0) - Don't Allow, (1) - Allow
