I found this server called Crafters SMP and it is all about long term survival. It is whitelisted and tries to feel like classic vanilla Minecraft with only a few plugins. The whole idea is to keep the same world forever.
They say the map will never reset. There are daily and monthly backups so builds are kept safe for a long time. This makes it nice if you want to start a big project without worrying it will get deleted.
The server started in January 2021 and it was made just to hold players builds as long as possible. It really feels like they want that old 2011 to 2013 style where you stay on the same world with the same people.
You have to read the rules and apply to join since it is whitelisted. They are looking for new players who want a stable world and a chill survival vibe with almost no resets and no crazy changes.
