Also, there's really no reason for this to be a special device. It easily be a blob on your computer's hard drive

Uh... If it was on your computer's hard drive and your hard drive failed, it wouldn't be much use as a backup system, would it?

The point is that your backups would be replicated to blobs on other people's hard drives, so you'd still be able to recover your data.
