On my desktop right now I have an encrypted 3TB Seagate External drive that I use for backups. I have BackInTime installed (similar to TimeMachine on Macs). I have it set up to backup once an hour. It saves all backups in the past two weeks, one backup a week for the last 8 weeks, one backup a month for the past 12 months, and one backup per year forever.
It uses rsync on the backend and It Just Works™.
