-- Restores a directory using an existing directory snapshot.
--
-- When you restore a directory from a snapshot, any changes made to the
-- directory after the snapshot date are overwritten.
--
-- This action returns as soon as the restore operation is initiated. You
-- can monitor the progress of the restore operation by calling the
-- DescribeDirectories operation with the directory identifier. When the
-- __DirectoryDescription.Stage__ value changes to 'Active', the restore
-- operation is complete.
