IABAK stores 100 TB, or 0.2% of it.
I also remember reading about Sia on HN, which is a dapp that pays hosts to store data and distributes it. Looking at the going rates on Sia ($1.45/TB/mo), that's $870k/yr. That's ~10% of the IA budget (which is only $10MM/yr, which sounds very efficient!) but shows that the order of magnitude is not that crazy.
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.

is that a "Million Million" eg. 10^12 ?
In this case, 6250*150 = 937500, almost a million.
Furthermore it would not be so hard to translate Archive.org items to IPFS objects, if there were an effort to pin a significant number of them to storage and network.
(50 petabytes * 0.2% = 100 terabytes)
[$0.005 ($/GB/Month) BackBlaze cost]
[(50 petabytes) / (1 gigabyte) = 50,000,000]
(50,000,000 * $0.005 = $250,000 US$)
—————
Meaning based on my numbers, that is $250,000 USD a month to host 50 petabytes of data on BackBlaze.
Also, those backups would be (relatively) cheap to keep, but not necessarily to restore.
I had constant issues with objects simply never (hours and many requests) being found, despite being pinned in several places; and the daemon sucked resources away from the system at an alarming rate back when I was trying properly.
With all that being said, maybe now is the time to look at it properly, the budgets are there. Maybe Juan, _prometheus, can find somebody to at least PoC this important application.
