If I understand correctly, the remote SAN of you can snapshot the 
storage domain(physical lun in the SAN) lively. And you hope to recover 
the storage domain with the previous snapshot stored in the SAN.
So you create a new "storage" domain for another data center and restart 
the VM from the newstorage domain. I am not sure if the VM disks in the 
storage domain snapshot is in consistent date if the SAN snapshot the VM 
in a running state. I think the VM OS should be notified and make sure 
it is in consistent state before the SAN can do the snapshot, also the 
VM OS should be notified with the finish of the snapshotting..
