-- Returns a list of virtual tape recovery points that are available for
-- the specified tape gateway.
--
-- A recovery point is a point-in-time view of a virtual tape at which all
-- the data on the virtual tape is consistent. If your gateway crashes,
-- virtual tapes that have recovery points can be recovered to a new
-- gateway. This operation is only supported in the tape gateway type.
--
-- This operation returns paginated results.
