I am using Backup Exex 12.5 on SBS 2008. For 6+ months my backups have been running fine, but last week they began failing with the following:
Backup- SBS2008 - AOFO: Initialization failure on: "\\SBS2008\Microsoft Information Store\First Storage Group". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS).
V-79-10000-11226 - VSS Snapshot error. The Microsoft Volume Shadow Copy Service (VSS) snapshot provider selected returned: "Unexpected provider error". Ensure that all provider services are enabled and can be started. Check the Windows Event Viewer for details.
I have been working with Symantec on the issue, but they told me it was a Microsoft issue. They did suggest that I install Windows Server 2008 SP2 to re-register all dll's, which I did, but that did not resolve the issue. I have checked that all of the services are enabled (Volume Shadow Copy, Symantec SymSnap VSS Provider, Microsoft Software Shadow Copy Provider, and some others they had me check).
I also receive the following errors in the system event logs:
