My suggestion: Buy 3x 28TB drives. Mirror the data to them. Then move them off site.
The off-site location could either be a family member’s home where you can then sync to the drives over the internet. Or in a PO box nearby that you retrieve them from time to time to re-sync the data.










Yeah, if 90% of that is movies/shows, then you really don’t need a backup of that as you can always re-download it. Then you have a 5TB backup problem which is much cheaper to solve.
