I have an issue with my file server and the volume snapshot service not working.

System - Windows 2008 Enterprise SP2 using Backup Exec 2010 R2 SP1 for DR

Backup Exec reports the following -

Microsoft Software Shadow Copy Provider and volume shadow copy service both are set to manual and are started (can be restarted w/out a problem)

Backup- xxx.xxx.xxx.xxx - AOFO: Initialization failure on: "\\xxx.xxx.xxx.xxx\U:". Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS).

V-79-10000-11217 - VSS Snapshot error. The Microsoft Volume Shadow Copy Service (VSS) snapshot failed. Make sure that all provider services and tasks are running. Check the Windows Event Viewer for details.


The application log shows this
Event ID 12289 source VSS
Volume Shadow Copy Service error: Unexpected error DeviceIoControl(\\?\Volume{4cc90149-05ba-4f04-8bc3-ba48ca58dbd8} - 0000000000000154,0x0053c008,000000000025B000,0,0000000000259FF0,4096,[0]).  hr = 0x8007045d.

and the System log shows
Event ID 1 source volsnap
The shadow copy of volume U: could not create shadow copy storage on volume E:.
(as well as for the other drives)

Hummmm, this kinda looks like a problem with the filesystem itself...  

I'd recommend that you start with some obvious things like running CHKDSK on all of  your volumes.

Drive E in this case was two hard drives in Raid 0 (used for backup), when trying to run CHKDSK on it the drive disconnected.  I disabled the drive in disk management and then disabled the drives in device manager and re-ran a backup and this time it succeeded without the VSS issue.

I will update on Monday to give time for other backups to complete and report back.
