And where does Amazon offer colo services? What they offer is Direct Connect at certain (non-Amazon) data centers. That costs about 20k per year for a 10Gb port, ON TOP of the colocation and cross connect fees you are paying at the data center where you want to establish the connection. If you want to bring the restore time down to 12 hours, you need 24 connections (and you need at least as many servers, no single server can handle 240Gb of traffic), so we are now at about 480k+X (large X!) per year per petabyte just for the connections you need in case you have a catastrophic failure (establishing such a connection takes days or even weeks, even if ports are available immediately, so you can't establish the connections "on demand").
That's not even talking about availability, as you are now getting into the realm where it starts to get questionable whether even Amazon has enough backhaul capacity available at those locations so that you can actually max out 50+ 10Gb connections simultaneously.
