how to lose data, part 237

Real pros never talk about their screwups, but I find them endlessly fascinating myself...
Despite my backups (to a SCSI DAT drive), I actually managed to lose some of my stuff in a disk crash: I had a directory called "Images" which was originally just a catch-all for stuff off the web I felt like saving, but it had gradually mutated into a place where some original work was being done (e.g. collages based on those images) and yet I neglected to add it to my list of backup locations.
Now, this wouldn't have mattered quite so much if I was running a seperate desktop and webserver, but that was during a period when my webserver had died, and my workstation was doubling as a webserver. I often succumbed to the temptation to "publish" things to my web site using symlinks, which did not make it any easier to keep track of the really important locations.
Obviously, if I'd been religiously doing incremental backups of my entire workstation, this problem would've been covered, but for better or for worse, I was mostly doing "quick" backups of the hot locations I cared about the most. If that seems cheesy, consider that backups you actually do are always going to be better than the ones that you meant to do -- there's something to be said for making your home backups quick and painless. And really, I lost a very small percentage of my original material: almost all of it was covered.
Anyway, I think this was an interesting gotcha. If you rely on a listing of which locations are "hot", then that listing is pretty hot too, and you'd better be keeping it up to date.
