Yes this seems to be the general theme. Main issue is sorting out a file system. I can use a self-repairing one, to recover from long term storage issues, but then it likely won’t work in Windows which it may need to if I want a layman to be able to access it. So still some refinement of the plan but it’s coming together.

I’ve also decided to print some physical photos, aiming for 100 per year, and will put everything in a container together. The physical photos are for in case the container is lost for decades and the drives die, then there will at least be something.
