I am trying to enable Windows Backup on Server 2008 R2 to backup my Hyper-V clients. I have taken care of modifying the registry to support the Hyper-V VSS Writer (added the GUID to the registry). When I run a backup of the volume that has the Hyper-V files, I get the following in the event log:

When I run "vssadmin list writers" command I get the following error on the Hyper-V VSS Writer (all other Writers are error free):
Writer name: 'Microsoft Hyper-V VSS Writer'
Writer Id: {66841cd4-6ded-4f4b-8f17-f

b}
State: [5] Waiting for completion
Last error: Unexpected error
I have re-started the server and get the same errors. Anyone got any suggestions? I have spent hours searching and the only hit I can find that I followed was that this could be because the OS volume is not marked "active". I found that Windows Server 2008 R2 creates a "System Restore" partition and marks that "active". I changed it so that my C: drive is Active and that did not fix it.
