-- | This operation lists the recovery points for a specified gateway. This
-- operation is supported only for the gateway-cached volume architecture.
--
-- Each gateway-cached volume has one recovery point. A volume recovery point
-- is a point in time at which all data of the volume is consistent and from
-- which you can create a snapshot. To create a snapshot from a volume recovery
-- point use the 'CreateSnapshotFromVolumeRecoveryPoint' operation.
