I pay for the Crashplan backup service and I’m quite happy with it. There is an option where you can backup to your friend’s computer for free. I’d like to trade backup space with a friend (you?) “just in case”. My backup is about 250 gig. I would happily trade about 250 gig on my computer with 250 gig on yours. What do you think?
The app runs with very low overhead. It runs on Windows, Mac, and Linux. Don’t worry, without the secret password I can’t view your data and you can’t view mine (assuming you trust the Crashplan software, which I do)
