There was a failure in preparing the backup image of one of the volumes in the backup set. Detailed error: The process cannot access the file because it is being used by another process.

Hi,

I have been getting this error message on one of the server I monitor for the multiple days now. It appears to only be happening to only 1 of my backup jobs.

I have checked the application and system log on event viewer there doesn't seem to be anything that could be conflicting with the backup job. In addition, I have also tried stopping the backup schedule and creating it again.

The following error in the backup log is: 

The backup operation that started at '‎2018‎-‎10‎-‎09T07:00:25.131017200Z' has failed with following error code '0x807800C5' (There was a failure in preparing the backup image of one of the volumes in the backup set.). Please review the event details for a solution, and then rerun the backup operation once the issue is resolved
