Hi,
We use System Center DPM 2012 R2 (running on server 2008 r2 sp1) to backup the system state/bmr of our domain controllers (running Server 2012 R2). Since the end of March the backups fail with the following error message:
DPM cannot create a backup because Windows Server Backup (WSB) on the protected computer encountered an error (WSB Event ID: 517, WSB Error Code: 0x11ECE20). (ID 30229 Details: Internal error code: 0x80990ED0)
When I check the windows backup logs on the domain controller (c:\windows\logs\windowsserverbackup\) there are three possible error messages:
"Backup of volume C: has failed. An unexpected network error occurred" or "Backup of volume C: has failed. Windows Backup encountered an error when accessing the remote shared folder. Please retry the operation after making sure that the remote shared folder is available and accessible" or "Backup of volume C: has failed. The parameter is incorrect".
When I follow the backup in Windows Server Backup the error occurs at the end of the backup process when the Description shows "Backup in progress..."
When I remove everything in DPM (Stop protection of member -> Delete replica on disk) and recreate everything in DPM the backup will complete succesfully but only the first time.
Any help appreciated.
DJITS.
