Why not dump the SQL data live to a text file and back that up?  That's what 
mysqldump is for... you can back up everything you need to restore an entire 
database without ever taking down the mysql server.  And this makes restores 
much simpler... if a developer drops an table by mistake, you don't have to 
restore the *entire* database back to a previous checkpoint, you can just 
extract the plain-text records needed to recreate that table and its data.

Check the options... the default settings don't capture everything, but with 
the right settings you can capture users, permissions etc.

A bit of tolerance is worth a megabyte of flaming.
