Windows 2012 R2 Std System State backup fails RRS feed

  • Question

  • Hi,

    Systemstate backup fails with below error :

    DPM cannot create a backup because Windows Server Backup (WSB) on the protected computer encountered an error (WSB Event ID: 517, WSB Error Code:  0x10A44C0). (ID 30229 Details: Internal error code: 0x80990ED0)

    What I did:

    1. Manual SystemState backup works fine locally on protected server (by running wbadmin start systemstatebackup)

    2. I see error in eventlog :

    The backup operation that started at '‎2016‎-‎08‎-‎29T14:36:11.512673100Z' has failed with 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.

    3. Checked logs in C:\Windows\Logs\WindowsServerBackup, i see error :

    Backup of volume \\?\Volume{77a8515e-c38e-11e5-80b4-806e6f6e6963}\ has failed. The mounted backup volume is inaccessible. Please retry the operation.

    4. i listed volumes using diskpart, i don't see any volume with above label

    5. Tried renaming windowsimage backup in C: (it was mentioned in one of the blog i goggled) 

    6.Restarted Vitual Disk and Cryptographic services

    Please help.
