To this day I still use a ZFS array for my critical backup storage. I've migrated over to using snap raid + mergerfs for my larger Linux iso storage array. Simple enough and I can pull a drive on it's own without any other stuff.
I'm still sitting on some 8mm film that my grandpa shot, and even some of the commercials he worked on. Still trying to find a reasonable way to digitize them.
Also multiple boxes of slides, I know you can buy the scanners (I had one). Wish there was a cheaper automated way hahaha
