If you are looking for a way to backup all of your MySQL tables daily and have them emailed to you, I found an awesome MySQL backup script that takes about 1 minute to configure and works perfectly right out of the box. Of course, you may have trouble emailing all of the files to yourself if you have a lot of dbs but, the script can make the backup to a local drive and you can then setup another cron job to ftp that file somewhere or not.

Plus, the script is very well documented on the site and the config file is well commented and super easy to read.
