What do you do for backups?

[tim]

I pose my sempiternal question: how do people back up their computers these days? Now that I have a Mac, I just let Time Machine do its thing. But what if my office catches on fire while my laptop and the backup drive are both in it? Should I have bigger priorities in that case?

Do you use network backups? If so, where do you get your 80 GB of online storage?

Helpful suggestions always appreciated.
