You can select snapshot virtual disks as the source virtual disk for a virtual disk copy. Selecting a snapshot virtual disk is
a good use of this feature, because it enables complete backups without significant impact to the storage array I/O.
However, some I/O processing resources are lost to the copy operation.
The Snapshot Virtual Disk feature can be used with the Virtual Disk Copy feature to back up data on the same storage
array and to restore the data on the snapshot virtual disk back to its original source virtual disk.
