I bought a tape library for my backups, but that's probably an overkill.

On the other hand, LTO-5 drives are now pretty affordable. And each tape cartridge holds around 2Tb of data for about $20.

Wait really ? That's a huge change from last time I looked. How much did this setup cost you?

		I kinda overdid it with a tape library (40 tapes capacity, LTO-9), but I'm using it for my company's AI model backups. _That_ setup was about $12k. I had a smaller setup before, with a simple external LTO-5 drive. Used drives are now are about $300, and you can probably find them cheaper. And LTO-5 is the minimum realistic version, it's the first one that supports LTFS and it has reasonable tape capacity.
