Well, it shows devices that have proven to work with Bacula in some form
or fashion, so if you're out to get one, you might investigate the ones
listed there.

True... in that case, shutting down MySQL and running the backup should
be enough (can be done with a 'run on client' script). Like mentioned in
another post, you might even want to use LVM do reduce your downtime:

- - shut down MySQL
- - initialize LVM snapshot
- - bring up MySQL again
- - back up from the snapshot
- - release snapshot when backup is complete
