BackBlaze B2 is $5/TB/month

Azure Archive is $2/TB/month ($1.68 if reserved)

AWS Glacier Deep Archive is $1/TB/month

GCP Cloud Storage Archive is $1.20/TB/month

Of course, there can be i/o and network charges, and different levels of redundancy (but possibly bulk discounts)...but the bare storage costs for for 50 PB per year would be roughly $600k - $3 MM/y.

The cloud business is a small fraction of Amazon's revenue but a large part of their profits. It's extremely profitable for them. That's why there is such a large discrepancy between (non bulk) HDD price and (non bulk) per month cost for archival.

Aren't the costs of getting that data out of the backup much larger than the cost of keeping it in the first place, to the point that when you actually need to restore a large backup, it turns out it was better to have been managing it yourself? That's the impression I got from various HN comments on the topic over the years.

Low cost to insert, low cost to keep it there, high cost to retrieve is exactly the combination you want when looking at disaster backup solutions, since you don't intend to retrieve the data frequently. Buy some earthquake insurance (I know, easier said than done) and only pay for 1/20 of the retrieval cost.

AWS has Snowball and Snowmobile though only used former to reduce data transfer costs. Dont remember what other savings are in there. Like is there price reduction if use with Glacier or not.

Isn't that inbound only? Getting the data out again is also required.

You can export data via Snowball as well.

The cost is only there if you transfer out of aws. Something like glacier will have a retrieval time on the order of hours or days.

Glacier Deep Archive does charge for retrievals at $0.02 per GB and additional $0.01 per 1000 such requests (both of which are $0.00 for Standard S3). PUT, LIST, DELETE are at $0.05 per 1000 requests, 10x the Standard S3 rates.

The majority of cloud costs of storage are bandwidth, so ignoring this makes the analysis meaningless.
