Does "Reinstall Server" delete my progress?
"Reinstall Server" sounds like a harmless repair button, but it isn't — it re-runs the egg's install script and can overwrite core files. This article explains what it really does so you don't lose progress.
What Reinstall actually does
Reinstall re-runs the egg's install script. Depending on the server type it can overwrite core/server files — it's not a safe "repair" button for your world. Your world folder often survives, but you shouldn't rely on that.
How to use it safely
- Always take a backup first — download your
world(and mods/plugins/configs) via Files or SFTP. - Consider whether Reinstall is really what you need. If your goal is to fix a broken server, try restoring a backup or fixing the specific error instead.
- Use Reinstall only when you understand it may wipe and you've backed up.
Warning: Don't treat Reinstall as a repair tool. It can overwrite server files. Back up before you ever click it.
Frequently asked questions
Will Reinstall keep my world? Often yes, but not guaranteed — it depends on the server type. Never rely on it; back up first.
My server is broken. Should I reinstall? Usually no. Restoring a backup or fixing the specific error is safer. Reinstall is a last resort once you understand the risk.
What's the safest way to repair a server? Identify the actual error (share your log via mclo.gs) or restore a known-good backup, rather than reinstalling blindly.
