for the case that the user selects only whole datastores, we do not
want to send and (exhaustive) list of snapshots that get restored,
but we only want to honor the mapping the user gives
this avoids using the backup restore codepath that iterates twice
over the tapes and would generally be slower for a lot of snapshots
