For the backup there shouldn't be a problem, it will only copy the
data to an xml file. During the restore part the unavailability period
occurs from erasing the db up to completely restoring it.  The
wait-until-queues-clear-out scenario will not be addressed since we'll
never know how long the pending tasks takes long to finished and we
are restoring the db to a previous state anyway.
