-- | Describes a data repository association\'s automatic export policy. The
-- @AutoExportPolicy@ defines the types of updated objects on the file
-- system that will be automatically exported to the data repository. As
-- you create, modify, or delete files, Amazon FSx for Lustre automatically
-- exports the defined changes asynchronously once your application
-- finishes modifying the file.
--
-- This @AutoExportPolicy@ is supported only for Amazon FSx for Lustre file
-- systems with the @Persistent_2@ deployment type.
--
-- /See:/ 'newAutoExportPolicy' smart constructor.

    --
    -- -   @CHANGED@ - Changes to files and directories on the file system are
    --     automatically exported to the data repository.
    --
    -- -   @DELETED@ - Files and directories are automatically deleted on the
    --     data repository when they are deleted on the file system.
