It's a question of how much you're backing up... my Tarsnap use and cost is very low.
I retain off-site encrypted HDD images updated once a month of things like media which constitute the vast majority of my data and do not need daily snapshots.
Yeah, I want to back up my media as well (around 90 GB), but I want my backups to just work. Tarsnap would have been fine if not for the cost, so a tool that combines EncFS + SSH + rdiff-backup will be ideal for me.
