The system is a Dell R720 running Microsoft Server 2012 with Hyper-V. The backup is configured to run every night at 2:30AM and backup the System state, 2 VMs and Host Component. Every other night the backups complete with a warning.
Time Message Description
11/12/2013 2:30 AM Backup Successful
11/11/2013 2:30 AM Backup Completed with warnings
11/10/2013 2:30 AM Backup Successful
11/9/2013 2:30 AM Backup Completed with warnings
When I check the details for the Completed with warnings, the System State Backup did not complete. When viewing the list of all backed up files it stops at the same point for the System State Backup. The error message is:
System state The operation ended before completion. Detailed error: The process cannot access the file because
it is being used by another process.
The event log has the following Warning messages:
Warning 11/11/2013 3:01:45 AM Backup 519 None
Warning 11/9/2013 3:02:34 AM Backup 519 None
Warning 11/7/2013 3:02:06 AM Backup 519 None
Warning 11/5/2013 3:01:47 AM Backup 519 None
The detail appears to be the same for all of them as follows:

I have tried changing the backup time to a later time and deleted the backup schedule and re-entered it.
I have been searching the forums but nothing seems to be related to my situation.
Any help would be greatly appreciated as the server is already in production.
Thanks,
Paul
