I have a Hyper-V cluster consisting of 6 x W2K12R2 nodes. I have installed the NBU 7603 client on each of the nodes and backup to a 2603 appliance is working well. Hyper-V integration services are installed on each of the nodes.
Restore, both full VM and individual file (GRT), is all working well. When I try and restore a full VM to a different node in the cluster, or to a different Hyper-V server altogether, my job fails with errors relating to Hyper-V snapshots, then socket write failures and finally a 2821 Hyper-V Policy Restore Error.
When I look at the application event logs on the Hyper-V server where I am trying to restore to I see VSS errors as follows:
Event 8194, VSS
Volume Shadow Copy Service Error. Unexpected error querying for the IVssWriterCallback Interface. Access is Denied.
I am initiating the restore from my Remote Admin Console, not the Hyper-V node.
I am specifying the second radio button on the Hyper-V restore screen, 'restore to a different location on the same server or an alternate server', and then I have to enter a path for the restored files. I cannot see any examples of the syntax of the path to be entered - what format should this be in ?
Why is the restore looking for VSS Snapshots ??
In summary, I can backup OK, I can restore OK to the same Hyper-V node but have this problem when re-directing the full VM restore to an alternate node.
Any advices welcome.
