Like sure I could convert the full drive to a container but that makes the backup and restore process untenable. On the backup side a 1% full 4TB drive is now 4TB to backup and it's no longer possible to deduplicate between drives. On the restore side to get one 5MB file off that 4TB drive i'd then have to download the entire 4TB container.

Ah, I see.
The backblaze backup cost is not size-based - people pay per computer, and this includes all internal and external hard drives (the external ones have to be attached every once in a while to be kept in backup). This definitely sounds like a game-able policy - what if I pay for a single computer license, and attach 100TB worth of drives there? What if I mount NFS share of my homeserver - can I backup it for the same PC fee a well?
I've used Backblaze backup for a long time (for my non-techinical friends) but never really thought long about how they can afford the flat price. Prohibiting non-physical drives would go a long way towards that. Looking at the docs, VeraCrypt can operate off the network drive, so I am guessing they had issues when it was used to present NAS/File share as a local drive?
Https is not a strong enough encryption protocol to convery exabytes of data without entropy.
