Windows 7 Backup Fails

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?

Solution 1:

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

Solution 2:

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.
