I've had an idea about remote backup for a long time. To pay ~50usd/month isn't that much of course, but very soon buying a large hard drive pays off. The problem with a local hard drive is that it's local, and if your house burns down, the drive does too. But what if you had your friens drive at your house and your friend had your drive at hers? You would rsync your computers storage to your friends drive, and she would rsync hers to your drive. It'd be seemless, and (presuming you both have all-day-internet access at home, of course) you'd be able to download backed up copies from your friends drive. Perks would be * Owning your data (=== controlling your data) * Being able to seemlessly encrypt it(=== owning your data) * Having lot's of space for cheap * Having a good reason to call your buddy But it would require you both to have a NAS or equal up all day. But I doubt it would save enough money that someone would spend time on it instead of buing space @ dropbox/google/etc.
