Hello,
I am experiencing sporadic Windows backup failures on my server. I am backing up to an 8TB USB drive and have tried multiple drives from different vendors. Some nights the backups complete successfully. Some nights I get the following errors:
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.
Other nights I get a warning with this message:
There was a failure while compacting the virtual hard disk on the backup location.
I have Antivirus completely disabled and have ensured that no other backup sets are running at the time of the backups. I have also disabled other non-Microsoft services. I have turned of all power-saving settings on the server. I can't seem to track down what
could be causing file locks. Any help is much appreciated.
