> but what ever happened to the 3-2-1 backup rule?

I wasn't 100% sure, but the data backs this up[0]; 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.

- [0] Interestingly, Ngram (https://books.google.com/ngrams/graph?content=%5B3-2-1+backu...) says ~2010 while Trends (https://trends.google.com/explore?q=3-2-1%2520backup%2520rul...) says slow build up from ~2020, guess "everyday" language would sit somewhere around those two different truths.

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.

The 3-2-1 rule is ~20years old at this point. But just because an archive is "old" doesn't mean we can't apply modern standards to that archive as time marches on, otherwise the BM_ARC would have never been build and opened a couple of years ago.

I mean, that 70+ year old archive must have been digitised at some point, unless Iron Mountain was storing the reel to reel tapes and/or film from the original recordings. So some "modernation" has been applied to it since its creation.

This has been a rule for like 30+ years (I have only been in the industry that long). Whether it was called "3-2-1" before that or not, the practice is the same. Have an onsite backup, have an offsite backup. This isn't a new concept at all.
