Hello all, I've got the following setup:

- Windows 2012 running DPM Server 2012 SP1

- Several Windows 2012 Servers running Hyper-V (2012 + 2008SP1 VM Servers)

For a majority of my VM's on the Hyper-V hosts I'm able to back up using Child Partition Snapshot - but I have a single VM server which refuses to be backed up using the Child Partition Snapshot (even though this server is identical - build from a VMM image as the other servers) and only allows Saved State.

The problematic VM server is Windows 2008R2 - the Hyper-V intergration agents are installed and all services running, the disk is not dynamic, the host is running, VHD is a fixed size and it NTFS.

I've tried rebooting the VM, moving to different protection groups without any change to the Saved State backup - does anyone have any ideas?

Regards

Simon
