This is the same method we use only diff is if the bottom drops out we
just reinstall the db from the ports and use the dumps to recreate
everything...I usually take the opportunity to upgrade as well...

On a side note we use (
http://www.ocsny.com/main/index.ocs?url=mysqlbackup ) to perform the
mysqldumps, as it has auto database discovery, thus we never have to edit
the scripts as databases are created or dropped...working on a postgres
version...


Cheers,
mikel
