-- | Retrieves the recovery point for the specified virtual tape.
--
-- A recovery point is a point in time view of a virtual tape at which all the
-- data on the tape is consistent. If your gateway crashes, virtual tapes that
-- have recovery points can be recovered to a new gateway.
--
-- The virtual tape can be retrieved to only one gateway. The retrieved tape is
-- read-only. The virtual tape can be retrieved to only a gateway-VTL. There is
-- no charge for retrieving recovery points.
