The world on your server is an ordinary Minecraft save. You can pull it down and open it in single-player, which is useful for building offline, testing something risky, or just keeping a copy you control.
What to do
- Stop the server or run
save-allDownloading a world mid-write gives you a copy with an inconsistent chunk in it. Stopping is safest;
save-alland a short pause is the compromise. - Archive the world folders on the server
Select
world,world_netherandworld_the_endin the file manager and compress them into one archive. Compressing first makes the download one file instead of thousands. - Download the archive
Through the panel, or over SFTP if it is large. SFTP handles multi-gigabyte transfers better than a browser does.
- Extract into your saves folder
Put the
worldfolder into%appdata%\.minecraft\saveson Windows. Rename it to something you will recognise in the list.
If you play a Paper world in single-player, the Nether and End will look empty, because the client looks for them inside the world folder. Move world_nether back in as DIM-1 and world_the_end as DIM1 first.
Open the download with the same Minecraft version the server runs, or newer. Opening it with an older client is the downgrade problem, and it can damage the copy.
The world appears in your single-player list and loads with your builds where you left them.
