Ruud Baars, one of our colleagues and System Center Data Protection Manager subject matter experts at Microsoft Services wrote several scripts to overcome a current limitation of System Center Data Protection Manager 2007 with Service Pack 1.
An abstract from the provided help (Recovering a Hyper to alternative.mht):
DPM2007 Sp1 does not offer seamless recovery of a protected Hyper-V virtual machine to another Hyper-V host and will be implemented in a future version of DPM. Until such time this blog offers an alternative based on the DPM capability to recover virtual machine files to an alternative location and the standard Hyper-V export/import feature.
This alternative uses 3 scripts that ease the tasks to perform and are described below. The concept is to export information ahead of time using the Hyper-V export feature and modify that to suite the Hyper-V import feature. Reorganize the DPM restored directory structure with virtual machine files into a more familiar structure and finally import the virtual machines.
The scripts can be downloaded here.
