This is a most excellent place for technology news and articles.
That's why I back up my data on stone tablets in Cunieform.
Seriously though, if you wanted data to last for centuries, what would be your best bet? Would it be some sort of 3D-printed mechanical storage? At least plastics are generally not biodegradable, though they are photodegradable, so I guess you'd want to stick your archive in a dry cave somewhere?
Or what about this idea of encoding the data in the DNA of some microbe and cutting it loose? What could possibly go wrong?
Archival grade m-discs, apparently. I had the same question. https://www.howtogeek.com/858426/whats-the-best-way-to-store-data-for-decades-or-centuries/

It's a shame their capacity lags so far behind current hard drives. And not many drives for these discs are still made, so what are the chances of them becoming unreadable just because no one has equipment to read them?
Cool! I can see how optical media could, in theory, be very long-lasting as long as you don't use materials that oxidize or otherwise degrade over time.
