  • I cannot get a backup of my server. Backup Exec 2010 and Windows backup both fail with this error

    It happens almost immediatly after starting a backup.

    The story behind this server is that is a recovery from a crash. It is a Vsphere 4 VM. It had a snapshot on it that VMware had made during a patch, and a Snapshop from Backup Exec 2010 when it was trying to make a backup.

    The server ground to a halt, rebooted and did not come back up.

    Since then, we recovered the server from a much earlier backup, recovered all the mail, but I still can't make a successful backup. I'm totally stuck on what to do next. Any ideas?

  • Thanks so much for the reply.

    ole32.dll succeeded

    oleaut32.dll succeeded

    vss_ps.dll succeeded

    swprv.dll succeeded

    When regsvr32ing eventcls.dll I got an error "The module "eventcls.dll" was loaded but the call to DllInstall failed with error code 0x8000fff

    When registering es.dll I got an error "the module "es.dlll" was locaed but the entry-point DllRegisterServer was not found. Make sure that "es.dll" is a valid DLL or OCX file and then try again (I'll see if I can find them on one of our other servers and retry this. looks like its not there)

    stdprov.dll succeeded

    vssui.dll succeeded

    when registering msxml.dll I got an error "the module "msxml.dll" failed to load. Make sure the binary is stored at the specified path or debug it. (looks like it is missing too)

    msxml3.dll succeeded

    when registering msxml4.dll I got an error "the module "msxm4l.dll" failed to load. Make sure the binary is stored at the specified path or debug it. (looks like it is missing too)

     

    Without those 2, or a reboot, it did fail again

  • Roger,

    Would it be possible for me to see the vssvc.exe dump created when the process crashed? Also a copy of the event logs would be helpful. Would it be possible for you to drop them on your SkyDrive with a pointer?

    Thanks,

  • sure, how do I do that?

  • Roger - Instead of using the free SkyDrive space included with Live accounts, please upload the system and application event logs to this Secure File Transfer Site- 

    https://sftus.one.microsoft.com/choosetransfer.aspx?key=b83f6c4d-8f17-4e83-b684-859240d354d3 

    Password: H$GBHEpwGtLO

    Choose the option to Upload data to Microsoft. Please upload the process memory dump created when the process crashes too.

  • Ok, i didn't find a minidump, so I just uploaded the apps and system logs.
    I did get a successful backup for no reason this morning.
    Monday, July 12, 2010 11:01 PM
  • Roger - Did the backup work again today? I'll downloaded the event logs and I'll take a look today. Please configure the system to capture process dumps using these steps -

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps
    Value Name = DumpType
    Data type: REG_DWORD
    Value Data = 2

    Once enabled, the dump can be found at %LOCALAPPDATA%\Microsoft\Windows\WER

    After the next failure please upload the vssvc.exe dump to the file transfer site.

    Thanks,

  • I did that with the registry and yea I got another good backup last night. Its confusing because basically all I did was run the lines above that Shaon Shan suggested, and moved the backups forward 4 hours so that they don't run the same time the databases on the exchange server run maintenance.

  • Roger - Thanks for the additional info. The lines Shaon prescribed basically self-register the VSS DLLs and solve a large majority of the VSS cases we see in support. It’s possible the registering of the DLLs coupled with the reboot brought the VSS Writers to a stable state. We don’t necessarily prescribe it on Windows Vista\2008 Server and higher because Windows component installation is manifest based, and most of the registry is locked down even to the Administrator.

     

    You mentioned you're no longer running parallel backup jobs. There is a known issue described in KB 975928 "A parallel backup operation may fail when the operation is performed by Volume Shadow Copy Service (VSS)". The symptoms are a little different (not a crashing VSS process) but you were running parallel backup jobs with a VSS failure so it wouldn’t hurt to update the VSS binaries by applying the fix. I would only do it if you continue to see back up jobs failing. Based on your system event log you're running - 6.00. 6002 Service Pack 2 so the article would apply to your OS. http://support.microsoft.com/kb/975928
