-- Describes backups. The results are ordered by time, with newest backups
-- first. If you do not specify a BackupId or ServerName, the command
-- returns all backups.
--
-- This operation is synchronous.
--
-- A @ResourceNotFoundException@ is thrown when the backup does not exist.
-- A @ValidationException@ is raised when parameters of the request are not
-- valid.
--
-- This operation returns paginated results.
