I know you said you've tried crash plan but why not use it? Simply seed the initial backups, move the drive to your neighbor's, add the seed to their Crashplan and the schedule it to run x days berweenny times? I do it and it's flawless. Yes it requires a computer but other than that it's great. Another thing I use is Bitcasa $99 a year but unlimited and offers mirroring.
