The backup storage location is invalid. You cannot use a volume that is included in the backup as a storage location.

I was about to do a large number of Active Directory changes on a domain controller and needed to grab a system state backup before proceeding.  I took a system state backup using the wbadmin utility on a 2008 R2 SP1 domain controller by using the following command from a command prompt:

wbadmin start systemstatebackup -backupTarget:c:

When running the command I received the following error message:

The backup storage location is invalid. You cannot use a volume that is included in the backup as a storage location.


The resolution for this problem was adding a new Key and DWORD value to the system registry.  Create the following:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wbengine.
Create a key called "SystemStateBackup"
Set the value of this entry as follows:
Name: AllowSSBToAnyVolume
Data type: DWORD
Value data: 1


After creating the registry key the system state backup now completed successfully.
