Complete backup of a system: Boot from a linux live CD and use dd to clone the whole disk(s) to (an)other disk(s).
Or use rsync (in e.g. a script) to copy the relevant directories and files to another disk.

Hi Kanna,

You should check out Rear (relax and recover). It's in the repos, great live backup and bare metal recovery.
