How to back up your Minecraft server

What to back up

• The worlds: world, world_nether and world_the_end (on vanilla, Nether and End are inside world).
• Plugin or mod settings: the folders in plugins/ or config/, which hold claims, homes, ranks and economies.
• Server files: server.properties, whitelist.json, ops.json and banned-players.json.

The plugin and mod .jar files themselves are easy to download again; their data isn't.

Back up safely

Copying a world while the server writes to it can give you a half-saved copy. Either stop the server first, or run save-off then save-all flush in the console, copy the files, and run save-on afterwards.

Backups on Jump

• Paid plans back up automatically every hour, keeping one from the last hour, one about a day old and one about a week old. Back up now in the panel takes one any time.
• Restoring is one click on the Backups page. Jump backs up the current state first, so a restore can be undone too.
• Jump also backs up on its own before risky changes, like switching version or installing a modpack.
• Free servers have no backups. Download the world from Files (or over SFTP) before anything risky, and now and then anyway.

The backups guide covers downloading a backup to keep on your own computer.

Restoring by hand

1. Stop the server.
2. Rename the current world folder (for example world-broken) rather than deleting it.
3. Upload the backed-up world folder in its place, then start the server.
