Gmail for online backups

Gmail as an online backup system
explains how, using a php script, you can backup essential files in your Gmail account, and recover them whenever you need to. Pretty much what I wanted to do with my Gmail space. I would not want to use that for personal emails – call me paranoid. So mailing lists and backups it will be, then. I should backup some zips and archives on Gmail space, and save my paid for server space for other goodies, like pictures.
