I'm not so sure. Literally the most famous online backup company is (or was planning to):
https://www.backblaze.com/blog/6-tb-hard-drive-face-off/
But I think that a massive read-only archive really is the only use for these things. I hope they go out of fashion,
soon. 

But I was thinking more of the 'small company postgres server' or 'charitable organisation postgres server'.
Someone is going to make this mistake, you can bet.
Probably not someone on THIS list, of course...
