All my Windows 2012 R2 VM's (that run on a 3-node Windows 2008 R2 Fail-over cluster) are backed up by DPM 2012 R2 (also on Windows 2008 R2) using Saved State instead of Child Partition Snapshot. I've checked the list below, but didn't find anything applicable to these VM's.
- 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.
I've set the registry setting SystemRestore\ScopeSnapshots to 0 for each VM, and checked the current state with the diskshadow tool (to make sure it wasn't just an erronous datasource text in DPM).
Can somebody point me in a direction on how to further investigate this problem? I'm running out of ideas for this one :-(
TIA!
