But, to answer your question, you could periodically back your data up on an external hard drive and keep it in a safe deposit box at the bank (or at your workplace, or at your mom's house, or in a ziploc bag with some silica gel buried five feet deep in the Arizona desert). This isn't as convenient as an automatic script, but this goes back to point #1 of my first post about security and convenience.
I should buy a second:
External hard drive -- to keep at your [mom/brother/girlfriend]'s house. Connect it to his or her computer, poke a hole in their firewall, and run rsync (use cygwin if it's a Windows computer). Like I said, do it yourself. Once it's set up, it's done.
1. Security is inversely proportional to convenience.
2. If you want something done right, you've got to do it yourself.
So, lesson learned: Be your own cloud.
That shit matters in the long term for interoperability...
That security part in particular should have your attention if you've been paying attention to the Snowden releases.
Yep, good point. That's why I use Nouveau at home. But again, remember, this is a gaming device -- and a beta release one at that. They're after benchmarks, and their primary objective is to legitimize the Steam Box as a viable gaming device to the gamers -- people who have a particular interest in performance, not long term open source altruism.
