Hello,
We have a 3 node Hyper-V 2008R2 Cluster with 20 VM's. We have also now some Windows Server 2012(r2) VM's on the cluster. The problem is that the backup of these VM's are only done trough saved state and not online. I already did some searching and I know it's a Hyper-V VSS problem that should be solved with setting a registry key inside the W2012 VM(http://mvanvliet.wordpress.com/2013/04/10/issue-windows-server-2012-virtual-machines-can-only-be-backed-up-using-saved-state/). But this doesn't work for me. I also checked this settings:
- Backup (Volume Snapshot) Integration Service is disabled or not installed.
- The virtual machine has one or more dynamic disks.
- The virtual machine has one or more non-NTFS based volumes.
- The virtual machine Cluster Resource Group in a cluster setup is offline.
- The virtual machine is not in a running state.
- A ShadowStorage assignment of a volume inside the virtual machine is explicitly set to a different volume other than itself.
- An App-V drive is installed on the virtual machine that creates a non-NTFS volume.
None of these are true. Does anyone have onther option to solve this? Thanks!
