-- | Describes the data tiering policy for an ONTAP volume. When enabled,
-- Amazon FSx for ONTAP\'s intelligent tiering automatically transitions a
-- volume\'s data between the file system\'s primary storage and capacity
-- pool storage based on your access patterns.
--
-- Valid tiering policies are the following:
--
-- -   @SNAPSHOT_ONLY@ - (Default value) moves cold snapshots to the
--     capacity pool storage tier.
--
-- -   @AUTO@ - moves cold user data and snapshots to the capacity pool
--     storage tier based on your access patterns.
--
-- -   @ALL@ - moves all user data blocks in both the active file system
--     and Snapshot copies to the storage pool tier.
--
-- -   @NONE@ - keeps a volume\'s data in the primary storage tier,
--     preventing it from being moved to the capacity pool tier.
--
-- /See:/ 'newTieringPolicy' smart constructor.
