Kirk, I use mysqlhotcopy and copy the databases to a new folder (which then gets backed up by Bacula). Obviously, this isn't something you want to do due to disk space restrictions. So in your case I'd also recommend LVM (as a previous poster said). You need to write a script that connects to your MySQL server and issues a FLUSH TABLES WITH READ LOCK in order to flush your database to disk. At that point you can create an LVM snapshot and then disconnect from the SQL server (disconnecting removes the read lock). Once Bacula has finished, you can have it kill the snapshot. This can all be accomplished using Bacula's "Client Run Before Job" and "Client Run After Job" configuration entries. Good luck! -Chris -- [email protected] mailing list
