Can I make a live backup of running Hyper-V virtual machines?

Hi, I’m in a situation here where it would be excellent if I could make live backups of running virtual machines on one of my hosts.  We are getting ready to implement a SAN and currently have two nodes but only one node is really running most of the vms.  My plan is to use the 2nd node in the setup of my SAN because the 1st node right now running the majority of the important vms really cannot be shutdown during the day for the most part because many people access those systems running in those vms.  We will be getting DPM 2010 very soon and ideally I would love to use DPM to make live backups of the vms running on the primary node so that when I join that node to the SAN and setup clustering/high availability I can simply use DPM to restore them to the cluster and nodes I desire.

The virtual machines running on the primary node are all at least 2003 server and a few 2008 server vms all with integration services installed.  Each virtual machine that was setup on the primary node was setup with differencing disks.  Can I install DPM on another physical 2008 R2 64 bit server and place the agent on the primary node and make live backups of those vms to another physical disk?
If those vms were setup using dynamic disks in hyper-v can they still be backed up live with DPM?

Thanks for your time and any advice you can give me.

actually i have read those and in part three it leaves with this:

"In the next article in the series, recovery of a Hyper-V server and an individual virtual machine will be discussed."

i can't find that article though.  don't believe there is anything in those articles that discusses backing up individual virtual machines that are running real-time.
