Windows 7 Backup Fails

  • AJ.

    I am trying to backup a Windows 7 laptop to my file server.

    The error code is 0x80070005. The Event Viewer shows this:

    The backup operation that started at '‎2011‎-‎06‎-‎06T19:56:48.283117300Z' has failed with following error code '2147942432' (The process cannot access the file because it is being used by another process.). Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.

    There were no applications running other than background services and the backup program itself. How can I resolve this?

    Try disabling your anti-virus while running it. Also, are you running it with administrative privileges.

    That error looks like an access denied error. Make sure the user the job is running as has access to where the output file is being written.

    You may want to check the system event logs for problems with Volume Shadow Copy Service. The backup should have access to all the files on the system if Volume Shadow initialized properly.

    If you can open a window to your file server and copy a file to it, you are probably in good shape there.

    Finally, run Chkdsk (Error Checking) on your C: drive (right-click on C:, select Properties, click Tools, click "Check Now"). If there is a problem accessing a bad file record, this should clean that up.

    The default in Windows 7 for the Windows Backup service is manual, apparently because it's only started on-demand when going through the official interface.

    From the Start menu, start "Backup and Restore", then click on "Set up backup". This will start the service and then bring up a dialog where (I hope) you can do the backup. I couldn't follow this further since my Windows 7 is in a virtual machine.

    If you're using another interface for the backup and want the Windows Backup service to always be available, then start Services.msc from the Start menu, double-click on the "Windows Backup" service and set its Startup type to "Automatic (Delayed start)".


    Another possibility is that a registry cleanup utility has destroyed a needed registry entry.

    Either rollback to a previous system restore point or get from another computer with the same level of operating system the contents of the following registry key

    This thread contains the registry update file for Vista, which may work also for Windows 7.
