I use DVDs for backups. All of my files (when compressed in tape archives) fit on three DVDs (one for /home, one for /var, and one for all other files; this includes all system files too). However, you might have more files than I have, so DVDs might not be suitable for you. See how many files you have so that you can see how many DVDs you would need, and then you can see if it is suitable for you or not.
