> the "3-2-1 backup rule" is a relatively modern concept, at least by that name. I also remember things like "have one backup in one place, another in another place" since before this mnemonic, but I feel like it's unfair to judge a 70+ years archive on something that just recently actually became a widespread mantra.

They signed up with them in 2019. Not long ago.

Even if it is a "new" concept, common sense isn't. Pretty much anyone who cares about their data will do the due diligence, and this is not something that requires technical chops. This has been a concern for well over 20 years!

It really sounds like some senior management trying to be cheap.
