This tool is mostly interesting for people trying to back-up Windows 2008 R2 CSV.
The back-up of Windows Server 2008 R2 CSV van be tricky. It is recommended to use a hardware snapshot provider. If there is no hardware provider available then you need to switch to serial CSV back-ups.
This process creates an XML file that is read by DPM. This works well when you have only a couple of Hyper-V servers to manage. But what if you had lots of clusters backed up by a single DPM server?
