I do the following occasionally (not often enough):
        1) I tar up the /etc directory
        2) I do a "dpkg -l > status-of-installed-programs.log" to keep track of what software I've installed
        3) I tar up the entire /usr/local directory tree into a separate tar file
        4) I keep all my important data files in /home/music-projects, and I rsync that up to an external USB drive periodically for backups. I also keep any code or scripts in CVS and rsync that one up too periodically.

A "system restore" is basically a reinstall from a distro CD. Then I use the status-of-installed-programs.log file to grep out a list of installed packages ("ii" status), awk to get the name of the packages, and then "apt-get install" them. Then I either gradually pick through the backed-up files in /etc and copy them over, or just wholesale replace the directory, depending on how much of a hurry I'm in. The data of course I've had rsync'ed onto a separate drive, so I just copy that one over.

This is a long process, and I've been getting sufficiently paranoid lately to have obtained an extra 2.5" PATA drivein an external USB enclosure. I'm going to format it and copy over my entire drive so that I have a "hot spare". If my drive dies, I can just (hopefully) replace it with the new one and off I go.
