I just signed up for Amazon Glacier. .01 cent per GB Storage costs.. backup to the cloud. They have free apps you can put on your server so that data can be backed up regularly to it.

I'll be backing up my family photo's/videos and music collection to it. That's about 300GB's of data Cost? About $3 per month.

The only downfall? 2 - 3 (hours?) to get a recovery. But if you have a Bunch of data that you need protected, and don't want to pay a bunch of money, and you don't need "instant" recovery, this solution is golden IMHO.
