And I also had some Sony DTF-2 backup tapes which were fine, only Sony dropped support of the format about 10 years ago. It's possible to hunt down surviving DTF-2 drives, but they're very scarce and hard to find.

The reality is that these formats are only as useful as both the media and the drives can survive. And that may not be forever.

We do have 100-year old 35mm film prints that can still play back if they were very carefully stored, and the technology needed to play them is relatively low-tech and easy to do.
At Magnext, we sell all kinds of legacy tape drives, some 20+ years old. The problem is usually finding the same software used to write the tapes on those old proprietary systems. Then there's the DLT tapes that can be written on the same type of tape, but from different drive types, and you need to know which drive type it was used with originally. Luckily LTO is a standard format now and allows reading backwards 2 generations, and with LTFS, there isn't any software putting a block on accessing your files.
