In the grand scheme of things the only thing on my server stack that's really worth anything is immich. The rest will have very little value to anyone once I'm gone. Plan is to create printed books from the photos and those should stay accessible for the future generations, our archive just needs a ton of work on creating those photos and possibly adding descriptions on who's on the pictures and when they're taken.
I don't really plan for ww3 nor solar flare frying half of the planet, but one thing that's a real problem is that if something happens to myself. My wife or kids don't know how to manage/access a majority of the stuff there is even if their everyday digital life is using network and services in it I've built. They'll be just fine without pihole or jellyfin, but data in immich/nextcloud is valuable and bus factor for the digital environment is pretty low.
I should at least verify that all server passwords are on my bitwarden vault and set up dead mans switch on that. Then they can at least get someone to pull the data out of the systems or even hire someone to maintain them. Best option would be if one of the kids would learn the ropes, but so far it doesn't seem like they're interested on anything like that.
