I wasn't the author but if I had to pick one set of scripts that have lowered my anxiety the most it's this: http://www.mikerubel.org/computers/rsync_snapshots/ http://www.mikerubel.org/computers/rsync_snapshots/ Long story short: you can use hard links + rsync to create delta snapshots of a directory tree. I use it to create a back up of my important directory trees. Funny story about this: I had really old HP "Lance Armstrong" branded laptop that I used for years. The above above script was on it and was rsyincing to separate machine so it was fully backed up. Because of that, I was actually hoping for the laptop to die so I could get a new one (frugalness kicking in strong here). My girlfriend at the time was using it and said "Oh, should I not eat or drink over your laptop?" and I responded: "No, please do! If you break it that means I can allow myself to order a new one."
