    Good Morning,

    I am attempting to setup a rotating daily backup on a server running SBS 2008.

    While I believe that I have everything setup correctly as far as the (third party) software goes, I have yet to get around this one issue: Unable to create VSS snapshot (0x81000101).

    I have corresponded a few times with a gentleman from tech support who has first turned my attention to the following hot fix from Microsoft.

    http://kb.backupassist.com/articles.php?aid=3039 (link within post)

    I have tried that, but the hot fix tells me that it is "not designed for this operating system", though it says clearly on the Microsoft page that it is.

    Next he had me crate a batch file called "FIXVSS08", I will post the commands if anyone wants them. After running the batch file and rebooting, the backup ran flawlessly and I thought we had it licked. However the next day I got the VSS snapshot error again. I ran the batch file again and then the backup ran without a hitch. Again next day, VSS error...I think see a pattern anyway.

    While I am usually not opposed to a good workaround, I would really like to try and resolve this on a more permanent basis. The idea of having to run that batch file and reboot the server kind of takes the automation out of automated backup...

    Any pointers in the right direction would be appreciated.

    Hello.

    It would be good if you can explain the contents of the batch file so that we can understand how it is helping as workaround & what the issue is to help you out.

    Thanks,

    Sriram [MSFT]

    okay, still working on this, tried different avenues, but still stumped...

    Try this:

    Create and Execute a batch file named, FIXVSS08.BAT:
    Please note the following:

    1.             You will need to run the batch file as Administrator.

    2.             This is only for Windows 2008 not Windows 2003.

    3.             After running the bat file, you will need to reboot the server to bring all of the writers into a stable state.


    Copy and paste the following into Notepad, then click Save As, to save it as FIXVSS08.BAT.

    rem FILENAME: FIXVSS08.BAT

    rem

    net stop "System Event Notification Service"

    net stop "Background Intelligent Transfer Service"

    net stop "COM+ Event System"

    backup still fails 80% of the time...

    any thoughts?
