So, like, when my box locked up (for no particular reason I could tell) and I had to wipe and re-install, three days after I got the thing, it wasn't that big a deal... just a few wasted hours... but now, I've got a substantial investment in it... how do I back this thing up, so I can re-flash it to where it is now, in case something breaks in the future and "bricks" it?
