I've started a Wiki page on this topic:
http://cms.galway.net:8080/OpenCmsWiki/Wiki.jsp?page=HowtoBackup
Please feel free to edit. If it becomes a good Howto doc I'll post
back to the list.

I did find more doc on backups after a more thorough scan of the MySQL
documentation:
http://dev.mysql.com/doc/refman/4.1/en/backup.html

It seems my best bet is to use the 'mysqlhotcopy' script. As stated
earlier mysqldump produces an output which does not always re-import
(even after the my.cnf adjustments)
