I'm fairly certain that the calculator you linked is incorrect. Unless I'm not understanding the Glacier pricing page, it should cost at most $1,240 to store 10TB for 30 days and then re-retrieve over the internet (even at the expedited retrieval rate).

The calculator shows the same setup (albeit with some of the rate information hidden) as costing $3,934.91

Backblaze B2 has no retrieval cost, so the same setup (storing 10TB for a month, then downloading) would cost only $250 (less than 1/3 of the cheapest Glacier option). Glacier is really only a viable option if you're sticking within the same region (where transfer is free) or you plan to literally never retrieve your backups.

Otherwise, B2 and other alternatives are much cheaper.

B2 has retrieval cost, the first 10GB each month is free.

I'm trying to use the nomenclature from the Glacier pricing page, where "transfer" is the verb to reference the cost per GB downloading the data from the remote provider. Glacier has an additional "retrieval" cost per GB that B2 and others do not (because they most likely have to physically retrieve a tape/HDD drive with your data on it).

Sorry I don't get it. With B2 I have to pay if I want to say download 100GB of data in B2. From what I read, you say this isn't so. But the pricing page state otherwise

[DisposableMike]

B2 has 2 charges: $/GB to store the data, and $/GB to download it (uploading to both is free)

Glacier has 3 charges: $/GB to store the data, $/GB to retrieve the data from "cold" storage, and $/GB to download it.

Retrieval !== downloading ("transfer"). Retrieval is an additional cost to downloading ("transfer").
