I feel that this is too complicated a solution for most people to follow. And it's not a very secure backup system anyway.
You can just get an external hard drive and use any of the commonly-available full-drive backup software. Duplicity is a free one and it has GUI frontends that are basically just click-to-backup. You can also set them up to give you weekly reminders, etc.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.

3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
