Interesting, but we run into the same issues as before. We are either storing locally (backups are good, but local storage doesn't have quite as much redundancy as a data center), or taking infeasible amounts of time to upload to a remote backup.

Ideally, we would be able to ship BluRays to a data center (USPS has terrible latency, but great bandwidth!), where they would load them into their servers. If anything happend to the local copies, we could either have them ship us back a hard drive or BluRays, or download the lost files (downstream is much faster for us, and because we are theoretically only downloading a subset of what we backed up, direct downloads are feasible).

The issue I run in to in my thought experiments is that a data center doesn't necessarily want to physically handle data shipped to them or create recovery media to ship back.

Actually, all that is really needed is a secure place to archive the BluRays. A way to view and download backed up files is a nice-to-have, but not required.
