29 wrz 2026 3 min czytania

Moving a colony between your PC and your Astro Colony server is easy. This guide covers how to download a save from your server as a backup, and how to upload an existing save so you can continue playing on MintServers.

Downloading A Save From Your Server

You can download a save either from the Files tab or from inside the game.

Method A: Using The Files Tab

Log into your MintServers panel and select your server.
Click the Files tab in the left sidebar.
Navigate to the AstroColony/Saved/SaveGames/DedicatedServer folder:

    📁 AstroColony
            📁 Saved
                    📁 SaveGames
                            📁 DedicatedServer (you are here)
                                        📄 SAVENAME.sav (your server's save file)

Find the .sav file you want and download it to your PC.

Method B: Downloading In Game

This method requires you to be an admin on the server. If you are not one yet, follow our Become Admin guide first.

Connect to your server. If you need help, see our Join Server guide.
Open the in-game menu and click Server SaveGames.
Select a save and click Download.

Saves downloaded this way are stored on your PC at %LOCALAPPDATA%\AstroColony\Saved\SaveGames\DedicatedServer.

Uploading An Existing Save

⚠️ Important Warning: Uploading a new save means deleting the save files already on your server, which removes any progress on your current colony. This cannot be undone, so download a backup first using the steps above if you want to keep it.

Step 1: Find Your Save On Your PC

Press Windows Key + R on your keyboard.
Enter the following path and press Enter:

📄 Run dialog

%LOCALAPPDATA%\AstroColony\Saved\SaveGames

Find your save, named SAVENAME.sav.

Step 2: Upload The Save To Your Server

Log into your MintServers panel and click Stop to shut down your server.
Click the Files tab in the left sidebar.
Navigate to the AstroColony/Saved/SaveGames/DedicatedServer folder.
Delete any other .sav files that are already in this folder.
Upload your .sav file into the folder.
Go to the Game Settings tab and make sure Should Load Latest Savegame is enabled.
Save your settings and click Start on the Console tab.

💡 Pro Tip: You do not need to change the Map Name setting to match your save file's name. The Should Load Latest Savegame toggle is what controls which save gets loaded.

💡 Large Files: If your save is very large or the upload fails in the browser, upload it over SFTP instead. See our SFTP connection guide for the steps.

🛠️ Troubleshooting

The old colony still loads: Make sure you deleted every other .sav file from the DedicatedServer folder and that Should Load Latest Savegame is enabled in Game Settings.
Server SaveGames is missing in-game: You need to be a server admin to use this menu. Add your Steam64 ID to the Admin List in Game Settings.
Can't find the save folder on your PC: Paste the path from Step 1 into the address bar of File Explorer. The folder only exists after the game has created a save on your PC.

Your colony is now on your server and ready to be played! If you are having trouble getting your save to load, no worries! Just open a support ticket and our team will gladly jump in and help out.
