DPM, Windows Server Backup and “The backup storage location is invalid” error..

While working with DPM, I came across an issue, where my internal backup of the DPM server, kept failing with “DPM cannot create a backup because Windows Server Backup (WSB) on the protected computer encountered an error (WSB Event ID: 546, WSB Error Code: 0x10851A0). (ID 30229 Details: Internal error code: 0x80990ED0)”

Upon closer inspection, when I launch an admin command prompt and attempt to perform a local backup using wbadmin:

I receive the following error:
The backup storage location is invalid. You cannot use a volume that is included in the backup as a storage location.

wbadmin_fail

The solution to this issue, is to simply add a new key to the registry.
Create the following:

wbadmin_registry

Immediately after creating the key, the backups should complete successfully.

wbadmin_success
