Backing up mt iBook

I’m fairy new to the Mac workd, I’ve had an iBook for less than 6 months. On my PC I know which important files I need to backup to be able to restore everything to how I like it, but what files do I absolutely need on my Mac?

Just back up your entire home directory. If your login username is jeremy, run something like

tar czvf /backupmount/homedir-date +'%m%d%y'.tgz /Users/jeremy

What Stusser said. Just backup your home directory; everything worth keeping goes in there.

is there a command to have it span the backups across several CDs?

Thanks, I’m using backup 3 and it seems simple.
