All, I see this error when I perform a backup of a Win2k3 VM running under
Windows 2008 Hyper-V. This is the full error:
DPM failed to fixup VHD parent locator post backup for Backup Using Child
Partition Snapshot\d2i-Credit on 2k8vm1.d2inet.net. Your recovery point is
valid, but you will be unable to perform item-level recoveries using this
recovery point. (ID: 3130)
Here is the kicker: the resolution steps instruct you to load the Hyper-V
role on the DPM server (yes you are reading this right) and do a
sync/consistency check. I do not find anything anywhere about needing to load
Hyper-V role on a DPM server. This is an issue for some clients who want to
run DPM on a non VT-enabled server. Anyone have some insight into this error?
The Hyper-V role on the DPM server is needed to perform item level recovery
from the backed up Hyper-V VMs. Item level recovery may include recovering
individual files/folders/volumes inside the guest OS, or the vhds of the VM
itself. You need to have a VT-enabled machine for that with the Hyper-V role
installed.
In case you do not want to perform item level recovery, you can ignore the
warning. Not having the role enabled does not hamper the backup or recovery
in any other manner whatsoever.
Thank you for the informative response Angad. So that I am clear, if you
do not install the Hyper-V role and you are backing up the VM, you can restore
and mount the entire VM. But, you cannot drill down inside of the VM itself
and restore an individual file within a VHD or a VHD alone. Am I correct?
