> I also remember things like "have one backup in one place, another in another place" since before this mnemonic

I've heard variations of this all the way back to some 1990s vocational IT courses in the country I live, and it wasn't even technologically advanced at the time. It's hard to have any sympathy for someone who misses this concept in today's age.

The concept of multiple copies in multiple locations already existed when backups on CD-R were common, so 20+ years ago. The “2” in the 3-2-1 rule refers to using different physical storage media and predates cloud storage.

I can pretty clearly remember hearing about the "3-2-1 backup rule" by name 10 or 15 years ago on the Security Now podcast with Steve Gibson. So it is _at least_ that old, but probably even older. The concept of having multiple backups is not at all new, however. Since I've been involved with computers (~30 years), I have heard folks say things like "two is one, one is none" in reference to backups and data replication in general.

Also, this TV station has not been sending their show archives to Iron Mountain for the past 70 years. Probably what happened was: In 2019, they had an on-site or nearby archive. Then some enterprising IT director came along and convinced management that they would save a bunch of money and time by outsourcing everything to a third party who said they could do it for cheap. Very confident in their genius, they then scrapped their own archive entirely.

Part of me pities them for ending up in this situation, the other part of me believes they got everything they asked for.

> 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.

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.

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.
