Yeah, but rsync only gives you a snapshot and not a history of your backup. When I really mess up, I want to go back to the state of my machine 15 minutes ago, or two days ago. This has saved me a lot of head scratching, trying to find out where I messed up. I really like the way timemachine works on the MAC. I can add as many disks as I want to the timemachine and it just sequences the backups between each of these disks. This happens every 15 minutes. If I loose a disk, then I loose 15 minutes of work.
I also have a SMART monitor that keeps an eye on the condition of these disks, looking potential disk failures. For Linux, I haven’t found anything equivalent to timemachine. BackinTime and the likes all try to do the same thing, but after a few weeks they all end up using tons of CPU time and become so slow. In essence, these solutions use rsync to create snapshots each hour and then use hard links to eliminate duplicating unchanged files. Currently I’m using Crashplan which performs well, but I don’t get the redundancy.
