Hi - am running Windows Server 2012 R2. Have been consistently running the Windows Server Backup (Bare Metal Recovery) on a nightly schedule, however recently it's stopped completing with this error. When I monitor the progress, I notice that it occurs right after "Creating shadow copy of volumes" completes successfully and it progresses to the System Reserved backup. It then changes to the "Removing deleted items" stage per usual, but it's at this point that it fails. I do not wish to reinstall this Windows Server from a clean install to lose this configuration and will move to an alternate product than Windows Server Backup if necessary. Preference would be to restore this functionality.
I've confirmed all vssadmin list writers show no errors. I've even done a wbadmin delete catalog and completely cleared all backups and recreated the backup schedule. Have run a chdsk /f on all drives and no errors are reported, including temporarily assigning a drive letter to the System Reserved partition of C:.
No new software has been installed on this server. No viruses or malware. The machine is completely current on all windows update. Even removed antivirus and re-ran the WSB and it consistently returns this same error.

At that same time the System Event (7031) is reported as follows: The Block Level Backup Engine Service service terminated unexpectedly. It has done this 2 time(s). The following corrective action will be taken in 300000 milliseconds: Restart the service.
The Backup > Operational log reports Event ID 100: The scheduled backup was canceled. To create a new backup, you must reconfigure scheduled backups or run a one-time backup operation.
There should not be any old items for this WSB to remove since I've already complete deleted all existing shadow copies with DISKSHADOW and deleted the wbadmin catalog to start clean.
It's almost acting as if something in the System Reserved partition on C: might have somehow become corrupted.
The Windows Server Backup logs folder includes a wbengine0.etl file that I cannot view, however there are no new *.log files created after this error occurs to give me help in resolving this issue.
I might actually considering paying for a Windows support ticket if it will restore this functionality.
Thank you in advance.
