I know it's a bit insane, but I do daily LTO-6 backups of my workstation. I was able to get a working setup for around $250 since I was willing to work with an "autoloader" drive, but honestly it works great and is really nice peace of mind to have my critical stuff protected. I keep banking to my iPhone these days -- though I can't say it's for sure safe. I probably should add that to the backup.
