Create a Valheim backup before updating, changing mods, uploading worlds, changing server settings, or testing a new branch. A backup gives you a restore point if the world or mod setup breaks.
- Open your Valheim server in the control panel.
- For the cleanest backup, stop the server first.
- Click Backup Server.

- Wait for the backup task to finish before making changes.
- Start the server again if you stopped it.
