The main advantage of mounting a read/write snapshot is very easy and fast recovery.
The machine can up and running in less than a min as described below
This will do following : restore vm by date with easy gui
1. poweroff or shutdown a vm
2. create vol snapshot
3. delete vm
4. create igroup with wwn
5. map snapshot to a lun (lun clone) and to a igroup
6. register the vm and poweron
7.svmotion to the original datastore
8. unmount datastore and unmap lun
9.delete lun
The time till full recovery is only between phase 1-6.
Phase 7-9 will be done in the background while the vm is up and running.
