Hello TN..
Quick background: We're running a Server 2008 x64 production box with Cobian Backup 11 "Gravity". Cobian is configured to perform hourly incremental backups from this server to a QNAP NAS.
The Application Event Log shows the following VSS errors:

...Any ideas of how I can rid the Event Log the above errors and how I can put the above writers in a "Stable" state? Any help would be appreciated, thank you.
