I seem to be having an issue with one specific server during a backup of the Shadow Copy Components. Here is the log:
V-79-57344-850 - AOFO: Initialization failure on: "System?State". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS). Snapshot provider error (0xE0000352): The specified volume does not exist. Recreate the volume, and then try the job again. Check the Windows Event Viewer for details.
I can't seem to find any helpful information regarding the error. The server is running Server 2008 Standard fully updated with Windows Updates. After reviewing the Event Log the VSS service successfully started and stopped and is not disabled. I'm not sure why this is the only portion of the backup failing.
