When database structure of the module and backup/restore in Moodle 2.0 will stabilise, there will be a need to write backup and restore functions.

It would be good to do that in automatised way, getting necessary information about db structure from install.xml and (if needed) additional file).

This issue is not top priority since there is need to wait before backup/restore library of Moodle 2.0 will stabilise.
