Windows backup fails RRS feed

  • Question

  • We are trying to backup server 2008, hyper v host, with 2 vms. Windows backup fails: the system writer is not found in the backup.

    Event log error:

    Log Name:      Application
    Source:        Microsoft-Windows-Backup
    Date:          11/22/2014 9:10:26 PM
    Event ID:      521
    Task Category: None
    Level:         Error
    User:          SYSTEM
    Computer:      VM01
    The backup operation that started at '‎2014‎-‎11‎-‎23T02:00:25.981000000Z' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2155348001'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.

    Nothing we seem to try fixes this any idea's would be appreciated
