Thanks for that. Looks like it could help with an issue I'm facing where VMs have been migrating between physical hosts during the backup process. Soon as they do, the backup dies, and we're left with a nasty snapshot consolidation issue. This should cure at least one headache for me.

Just did some testing with a compatriot on our environment here. Looks like not only could we specify the cluster name as our physical host, but we could also specify the vm datacenter name, or even our vBlock/vCenter name. So far, so good!

At this point, you can specify whatever you want - there is no real check.
