We have a Windows 2012 Domain Controller VM that we would like to backup the System State using DPM. Agent has been installed and the Windows Backup has been added.
When the backup runs in DPM, the job fails. Here is the error code:
- DPM cannot create a backup because Windows Server Backup (WSB) on the protected computer encountered an error (WSB Event ID: 517, WSB Error Code: 0x12363C0). (ID 30229 Details: Internal error code: 0x80990ED0)
When we try and create the backup using Windows Backup, the following error is in the log file:
- following error code '0x807800C5' (There was a failure in preparing the backup image of one of the volumes in the backup set.). Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.
We have tried attaching a separate drive and backup to a shared location. Both fail.
We have tried backup of just a few files on the DC instead of the System State, this fails as well.
All VSS Writers show as Stable with no errors
Server has the latest updates
Server has been rebooted, same issue
VM is Windows 2012 on a Windows 2008 R2 clustered host and is using Dynamic Disks (not fixed disks).
Anyone have any thoughts on what could be going on?
