Hi
We were backing exchange and system state ok till around 2 weeks ago.
It started failing with error
Backup- OPTICSBS2008 - AOFO: Initialization failure on: "\\OPTICSBS2008\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 followed different links on the forums and server does not have other vss providers than microsoft system provider below output of vssadmin list providers
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001-2005 Microsoft Corp.
Provider name: 'Microsoft Software Shadow Copy provider 1.0'
Provider type: System
Provider Id: {b5946137-7b9f-4925-af80-51abd60b20d5}
Version: 1.0.0.7
I have reregisterd vss writers but that did not help, tried to run it with AOFO set to automatic and to use Microsoft system provider, tried to do that withot AOFO option, but still same issue.
Have uninstalled BE and installed it back still the same issue.
Any help would be appreciated.
