error code 0x80070020

I am using windows 7 and trying to backup to a removable device.The backup does not complete successfully and I get a message of "the process cannot access the file as it is being used by another process". The only way of getting round this is to restore the computer to an earlier date which is not what I want to do. Any easy to follow advice would be appreciated
