  • Question

  • Hi.

    When i run my backup job i get this error message(e-mail):

    The following alert occurred at 12.01.2012 16:11:00.

    Status: Active
    Description: Backup to tape failed.
    DPM cannot create a backup because Windows Server Backup (WSB) on the protected computer encountered an error (WSB Event ID: 546, WSB Error Code:  0x80780034).

    I have also tried to run a backup job from WSB, but that also fails.

    My system is windows server 2008 R2, 64bit.

    Have innstalled all windows updates.

  • Hi Krisna.

    The backup job (WSB) fails with this error message:

    Windows Server Backup

    The creation of the shadow copy on the backup storage

    destination failed.

    The message appears after i have set up the backup job and click the Backup button.

    I also tried to run a backup from the command line, it gives the same error message.

    No entrys in any of the Windows logs.
