Bets tool for mysql backup?
 

Is there a piece of software which can take a backup of all the present mysql database if I just feed it a login and as password for the server?

phpmyadmin

Only one I've been using is "mysqldump", but then again, I'm lazy.

scripts exist to backup db, one by one, and email them to you ( or upload on another server ) . Setup with a cronjob.

Sounds interesting, can you point me in some direction?

Also, i've found it works very well to have the script run through a cron job as he said, and have them e-mail them to you ad a dedicated gmail email address for that sql archive.
