Hard ways of doing this:

dd - create an "image" of your whole harddisk (eats up time), so you can later simply use dd to put it back to a harddisk of the same size (well you can do it to a bigger one I guess, but it needs some tricking).

cpio - copy all the files into an archive that can be put back later.

I suggest cpio if you have files you need to save (Linux understands quite everything as "files"). Tar works the same way, but cannot include character special files, cpio should be able to do that too (as far as I know). dd gives you a perfect copy of the drive but you can only put it back as a whole; with cpio you can choose a bit.

There are probably..umm..more sophisticated methods, but I myself use cpio alot. dd I usually use only for small drives (usb thumb drives less than 1 gigabyte)..

The easiest (for me) for making backups are the "restore" and "dump" utilities.
Particularly, restore -i is wonderful for recovering those alone files you lose.

They also talk wonders about "amanda".
