Issue Backing Up Hyper-V Cluster

I've got Problems Backing up my Hyper-V Cluster

Environment:
Hyper-V Cluster with two hosts thsrvvm01 and thsrvvm02
Backup Exec 2010 on separate Server thsrvbak01 with Hyper-V Option

For All Hyper-V-Machines that are running on thsrvvm01 Backup fails with the following error:

  AOFO: Initialization failure on: "VRTSRV::\\TH-HVCLUSTER\Hyper-V?HA?VM\THWSNAV01". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS).
Snapshot provider error (0x173D): 0x 173d (5949) Check the Windows Event Viewer for details.

The Only Entry in Eventlog that could be related is the following

Server: thsrvvm01
Source: VSS
EventID: 8224
Description: The VSS service is shutting down due to idle timeout.

The Backup worked create a while ago. I'm not sure why it's failing now. There were no changes on the Servers.

Any help greatly appreciated


  • 1st thing to try would be updating the remote agent on all the nodes and rebooting the server and see if that helps
    Check the following document

    Agent for Microsoft Hyper-V Server Granular Restore (GRT) Backups to disk performed on a Windows 2008 R2 Backup Exec for Windows 2010 media server fail to mount one or more virtual disk images.

     In Backup Exec 2010, Tape based Granular Restore Technology (GRT) backup of Cluster Storage Volumes (CSV) enabled Hyper-V Guest Machines that has pre-existing snapshots created ,completes with exception: Failed to mount one or more disk images during backup

  • Also try re-registering registering the dlls that are needed by the VSS service
    1.From command prompt:

    Cd windows\system32
    Net stop vss
    Net stop swprv
    regsvr32 ole32.dll
    regsvr32 vss_ps.dll
    Vssvc /Register
    regsvr32 /i swprv.dll
    regsvr32 /i eventcls.dll
    regsvr32 es.dll
    regsvr32 stdprov.dll
    regsvr32 vssui.dll
    regsvr32 msxml.dll
    regsvr32 msxml3.dll
    regsvr32 msxml4.dll


     

  • I first updated Backup Exec on the Media Server. Afterwards I updated the Remote Agents. I also Installed all Windows Updates. Now It works. Thanks
