That is a good idea. I have considered having a network service like that, but I'm a little too paranoid. I want something that will survive heretofore unseen events, like a 0-day remote root exploit in the Linux kernel networking stack. If such a remote root exploit exists, and the person that discovers it decides to write something like the Code Red worm from 2001, and also decides to have the worm erase all block devices, I'd currently lose every file I have and all of my backups, even though they are geographically dispersed. It's possible that even services like S3 and Dropbox would be wiped in such an event. Once again, I realize I'm unusually paranoid in this regard, but I really don't want to lose my stuff.
