No such thing as "enough" when it comes to backups.
Day-to-day backups I manage using a network share on my home office LAN and Second Copy 2000. (Runs every few hours, saves the last 8 revisions of any changed files. Files are stored in a simple directory tree that mirrors the original directory tree so restores are quick-n-easy. I could also use rsync, but that doesn't do the multiple revision tracking.
Source code, of course, gets stored in a SubVersion tree.
I'll fire up Acronis8 or Knoppix (plus NTFSClone) every month or two and image the entire drive. Bit of a chore on the laptop because I'll remove all regular data first before doing the image. That keeps the image size very small (small enough to fit on 1-2 DVDs). My restoration plan is to restore the image, then reload data from my latest backup.
Long-term backups are a trio of removable drive trays that get rotated to a safe-deposit box across town every so often.
Long-term archives are done in a similar manner. ZIP everything up, toss it on a DVD with lots of PAR2 recovery data (10-25%). One copy for the shelf, 2nd copy for the safe-deposit box.
I used to use mirrored drives on the workstations. Lately I've simply given up on that (relying more on periodic imaging of the O/S). I use the 2nd drive as a near-line backup instead. The servers all use Linux's Software RAID.
Holy Crap! I need to rework my backup plan, seems I'm not doing enough! I am talking mostly personal data with some work db's reports, contracts, templates for methodologies etc. LOL
Now I think I will also need an offsite backup, and perhaps a whole duplicate environment ready to go in case something does happen. At least I could then still play games aswell as have my data HMMM!
Scrapyard, you have some expertise in revision management I see? I did some config management software implementation and support myself. Honestly, for me, it is was the dullest software going. No offense, just not my game! Maybe I can ask for you help on something... Any suggestions on xp pro comp at home, I'm looking to strip the drives, I know about fault tollerance problems but now does seem to be a good time cause its still half apart and sitting on the floor with my coffee resting precariously on the edge of the case

Any suggestions/warnings?
