I have three backup systems. My main backup is a local harddrive formatted with btrfs. I have a script in cron.daily that runs rsync then makes a btrfs snapshot. In addition to that, I run crashplan to back up my computer to the cloud. In some sense, this is actually my main backup because I trust them far more than I trust my own backup system, but it is not as convenient to restore from than a local drive (but still quiete convenient). I also keep have a two small hard-drives in a safety deposit box. These drives are exact mirrors of each other and tested/updated once a year.
