VSS Snapshot error

Hello, I am running BE 2012 and I'm trying to back up a new server. Since the server is offsite it is acting as it's own media server. When I try to back it up I am receiving:

- Snapshot Technology: Initialization failure on: "\\ServerName.DomainName.com\System?State". Snapshot technology used: Microsoft Volume Shadow Copy Service (VSS). V-79-10000-11226 - VSS Snapshot error. The Microsoft Volume Shadow Copy Service (VSS) snapshot technology selected returned: "Unexpected provider error". Ensure that all provider services are enabled and can be started. Check the Windows Event Viewer for details.

I tried turning the AFO to software for the provider instead of Automatic. No Dice. The job is also throwing exceptions for every other component to the server in regards to VSS. When I check the event logs I receive 2 errors corresponding to one job:

Volume Shadow Copy Service error: Error calling a routine on a Shadow Copy Provider {b5946137-7b9f-4925-af80-51abd60b20d5}. Routine details EndPrepareSnapshots({4a616c26-02a5-42f0-a4a0-f35e21f6925c}) [hr = 0x8000ffff]. Operation: Executing Asynchronous Operation Context: Current State: DoSnapshotSet

AND One saying the backup job failed... Can anyone give me some insight on how to fix this?

  • I think Maurijo has a good point...  Why not try to reregister the vss writers via script...  Obvisously I will back up all of my files before trying and then give it a go...  If it works great, I saved myself a 4 hour round trip car ride and a long day...  If not I am going to have to rebuild it anyway...  I know it seems like a shortcut but honestly this is a very small server that really is only used for roaming profiles at the momment...  Does anyone have a script to reregister the vss writers on a server 2008 r2 x64 box?

  • I used the one that is on the microsoft technote.
