MarvinMC A world is a folder, not just level.dat. Download its complete contents so that chunks, player data and other world files are preserved. A panel backup is the easiest way to keep all server files together.
Step by step
- Open Files and read level-name in /server/server.properties. For level-name=world, the main world is /server/world. Multiworld plugins can manage additional folders.
- Open Backups, create a backup and confirm the required stop. Wait for the completed notification, then download the dated tar.gz archive.
- Extract the archive locally with an archive tool that supports tar.gz. The panel backup contains the runtime files at its root; find the world folder next to server.properties.
- Keep every dimension belonging to the world. Depending on software and version, Nether and End data can be inside the world or in separate folders such as world_nether and world_the_end. Do not discard or blindly merge them.
- Alternatively, stop the server, wait until it is offline and connect with an FTP client using the details in FTP / MySQL, preferably with TLS. Download the complete world folder and any separate dimension folders recursively from /server. Restart after the transfer finishes.
- Check that the local copy includes level.dat and the world data, and that the transfer reported no failed files. Keep an untouched copy before testing it elsewhere.
Check the result
The file manager downloads individual files; it does not turn a folder into a ZIP. Use a downloaded backup or an FTP client for a complete world. Separate MySQL data requires its own export.
Important
Do not copy a world while the server is writing to it. For another server or singleplayer, check the Minecraft version, mods and dimension layout first. Java and Bedrock world formats are not interchangeable.
