--
-- Creates a snapshot of an existing Amazon FSx for OpenZFS volume. With
-- snapshots, you can easily undo file changes and compare file versions by
-- restoring the volume to a previous version.
--
-- If a snapshot with the specified client request token exists, and the
-- parameters match, this operation returns the description of the existing
-- snapshot. If a snapshot with the specified client request token exists,
-- and the parameters don\'t match, this operation returns
-- @IncompatibleParameterError@. If a snapshot with the specified client
-- request token doesn\'t exist, @CreateSnapshot@ does the following:
--
-- -   Creates a new OpenZFS snapshot with an assigned ID, and an initial
--     lifecycle state of @CREATING@.
--
-- -   Returns the description of the snapshot.
--
-- By using the idempotent operation, you can retry a @CreateSnapshot@
-- operation without the risk of creating an extra snapshot. This approach
-- can be useful when an initial call fails in a way that makes it unclear
-- whether a snapshot was created. If you use the same client request token
-- and the initial call created a snapshot, the operation returns a
-- successful result because all the parameters are the same.
--
-- The @CreateSnapshot@ operation returns while the snapshot\'s lifecycle
-- state is still @CREATING@. You can check the snapshot creation status by
-- calling the
-- <https://docs.aws.amazon.com/fsx/latest/APIReference/API_DescribeSnapshots.html DescribeSnapshots>
-- operation, which returns the snapshot state along with other
-- information.
