DPM 2012 backup fails with ID 3114 : DPM encountered a persistent VSS failure RRS feed

  • Question

  • Hi,

    We are having Lync 2010 installed in Hyper V Cluster of windows 2008 R2.

    For whole VM Backup, we are using DPM 2010 and configured all VM backup. We have shared iSCSI storage for VM Creation.

    On very first backup all goes well, but on the next backup cycle backup fails with following error.

    ===============

    Affected area:    \Backup Using Child Partition Snapshot\<Server Name>
    Occurred since:    10-08-2012 09:01:17

    Description:    Recovery point creation jobs for Microsoft Hyper-V \Backup Using Child Partition Snapshot\<Server Name> on <Server Name FQDN> have been failing. The number of failed recovery point creation jobs = 1.

     If the datasource protected is SharePoint, then click on the Error Details to view the list of databases for which recovery point creation failed. (ID 3114)
     DPM encountered a persistent VSS failure and hence restarted some VSS services to rectify the failure. (ID 32561 Details: Internal error code: 0x809909C3)
     More information
    Recommended action:    Check the Application Event Log on <Server Name FQDN> for the cause of the failure.

    ==============================

    Also all the time the very first backup done in 50 Mins max, but the next backup it never completes (Takes 12 Hrs), and we need to cancel the job manually.

    The same backup if configured again by deleted the Protection Group, Works for first time only.

    I have check the following.

    1) All Protected servers can be ping from DPM server. 2) File sharing is possible among all. 3) DataSourceGroups.xml is proper 4) All VSS Writers are on stable state on all servers

    Need help if anyone have resolution to this.

  • Hi,

    Check the application event log on the node hosting the VM during backup and check for VSS errrors, and the system event log for volsnap errors.

    You may need to work with the Windows forum to help troubleshoot.
