The 3-2-1 Backup Rule – Why Your Data Will Always Survive (2019)

I mean, it's a one time investment that's may be good for a decade or so, depending on the setup and workloads.

But yes, forking over a 2 to 4k for a new LTO-7+ changer isn't a small investment for private use, for a company it's IMO a no-brainer though.

FWIW: You can get them often cheaper, e.g., at ebay or whatever your local online reseller space is. For example, one can get LTO-5 ones here for 300 - 400 bucks and LTO-6 for 600 to 800. While LTO-6 only has 2.5 TB of space you can also create tape-sets (e.g., spanning multiple tapes) and for the more important data it may even be enough.

ages ago there also was always the recommendation that you should have two drives, so if one gets out of alignment you'll notice when it starts to create tapes that proper drives can't read anymore. Not sure if that's still a concern with modern ones?

No, that's not really a concern currently, and I actually never heard that in combination with LTO - which is relatively modern.

Good to know. Quite possibly folklore that got transferred over to LTO.
