Backups fail - "Computer failed to take a snapshot of the volume for backup" RRS feed

  • Question

  • Using Win 7. Made sure Volume Shadow Copy service enabled (it was stopped on the server but I restarted). Did a chkdsk /f/r of drives. Reinstalled latest connector software. Nothing seems to work.

  • The below MIGHT be a wild goose chase, but it worked for me ----

    I had this identical problem [except for the O/S] on and off this past week to ten days. Did the same thing you did, got no where to get the automatic backups running again.

    I was pretty sure the chkdsk /f/r was a wasted effort after several runs of nothing found wrong with the drive.

    Then I was fiddling around and I said to myself ... "it's been a while since I ran Malwarebytes Anti-Malware". Much to my surprise, my machine got whacked by a new variant of "Vista Defender Pro" [real bad one]. It [Malwarebytes'] fixed it - i.e. it got removed. Then I rebooted.

    Backups started working again after its removal. Diving deeper in research [Google] I found this evil thing effects some EXE files across the entire hard drive!

    It messed up this part of the registry file:

    HKCU, Software\Classes\.exe
    HKCU, Software\Classes\secfile
    HKCR, secfile
    HKCR, .exe\shell\open\command

    My disappoint is with Norton Anti Virus 2010 - it never saw it - the Spyware. The first time in 10 years it let me down. :(

    Automatic backups are running just fine now.

  • Right, I read in another post to try Malwarebytes. Tried it but it didn't find anything. Thanks.

  • Well so much for the wild goose ...

    Another thing to look at or try - - -

    I had two clients - customers not PCs that used Norton Ghost 12.0 and Acronis True Image 10 or higher that were used for backing up their machines prior to their WHS box. Both screw around with the Registry and VSSADMIN.

    Go to a DOS prompt [CMD].

    Type in

    VSSADMIN List Providers

    You should get something like this excluding the user name -

    C:\Users\Michael>
    C:\Users\Michael>vssadmin list providers
    vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
    (C) Copyright 2001-2005 Microsoft Corp.

    Provider name: 'Microsoft Software Shadow Copy provider 1.0'
       Provider type: System
       Provider Id: {b5946137-7b9f-4925-af80-51abd60b20d5}
       Version: 1.0.0.7

    Norton [Symantec] and Acronis should not be in the list. Acrnonis True Image can be stripped out and then a reboot and WHS backups will start working.

    Symantec's Norton Ghost is a nightmare if it was used before WHS for backing up. Once it [Ghost] is removed from the hard drive and it's service removed as a provider under VSSADMIN List Services I still can not get WHS backups to work on that machine. I know of only one crappy way - reformat the hard drive and reinstall the OS which is a bummer.

    You might want to see if this is the same -

    at the DOS prompt

  • I started having this problem shortly after configuring my Vista Ultimate system to dual boot Windows 7 Professional.  Didn't happen immediately, but about a week afterward.  Windows 7 installation was on a separate, new drive.  Could temporarily fix the problem by going into CP, Device manager, selecting view hidden devices, and deleting all the Generic Volume Shadow Copies under Storage Volume Shadow Copies.  After a reboot, there would be just as many volume shadow copies, but the machine would back up for another week or so, then fail again.  Finally, I re-configured the backup to only back up the Vista drive.  Since then, the machine has been backing up perfectly.
