I am getting the following errors messages when trying to create a backup image:
There was a failure creating the backup image in one of the volumes in the backup set (0x807800C5)
The process cannot access the file because it is being used by another process (0x80070020)
I have also attached a screenshot of the error message.
I have tried running sfx /scannow and that does not fix the problem.
This is a link to the event log entries when the failure occurs:
