Hyper-V Virtual Machine Backup Script, which shuts down the VMs.

This Script Shuts down all the VMs first then takes a VSS Snapshot, Starts the VMs, exposes the Snapshot and uses robocopy to copy the VMs.
This is meant for a Stand Alone Hyper-V Host with Direct Attached Storage and will not work on a Cluster.
