[Endlessly]

Since numbers are not 100% clear...

(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.

That's a fraction of the AWS bills for many startups arguably doing absolutely nothing

They have VC money to burn. Archive.org doesn't.

Also, those backups would be (relatively) cheap to keep, but not necessarily to restore.

I would guess restore wouldn't be a problem. AWS or whoever would do it for free given it is a non-profit (in case of a disaster only, of course).
