My current backup setup consists of a 160GB external hard drive hooked up to a G4/400 Cube. I’m using a combination of ChronoSync and some shell scripts to create a nice archival backup of my home folder. (I don’t bother with apps and stuff because I’m too cheap to get a larger drive.)

Now there’s Time Machine in Leopard, and I’d really rather use it. It’s fully supported, so there’s no need for scripts and hacks, plus it has some nice features with iPhoto, etc.
