Electricity isn’t a given during an emergency tho. I think the focus is on non perishables

That’s really good advice actually, thanks. And under the bed like the other guy said isn’t impossible either.

That’s cool and all, but where do I put all this shit. I live in a 3 room 60m² apartment with my family of four because of the insane rent. I literally do not have space to hord anything.

If your main motivation is never going through that kind of digital loss, please please please do yourself a favor and do not rely solely on a local solution. If there’s a fire in your apartment, the best nextcloud setup isn’t going to do shit for you. Look up the 3-2-1 rule if you want to be safe.
