We're looking at using rsync from within our VMs to back them up. And plain dd to image the VMs while they are not running.
Thanks Phoenix,

All my VMs are just file based, and one large file for each virtual hard disk.

I am aware of the need to pause the VMs, hence my question on how you were snapshotting. I could possibly pause the VM as I am building a second box as a clustered backup so that box would failover and serve the web while the backup is being preformed. I am planning to rsync the vms across the netowrk to keep them in sync. That should eliminate the need to replicate the SQL databases since the vm viruall disk will be replicating all the time via rsync. Do you see any problems with this approach?
