Satisfactory server backups and saves

Your Satisfactory factory is backed up every time the server sleeps, and every 10 minutes while it runs. You can also make a backup by hand, restore any of them, or download one as a zip. This page also shows how to move a single-player save, or a save from another server, onto yours.

How backups work on Wilderack

Backups hold your saves, settings and mods. They never contain the game itself, which installs fresh from Steam.

The game also keeps its own safety net. It writes rotating autosaves, 3 by default, and can save each time a player leaves. Those live next to your saves, and you can load them from the Manage Saves tab.

Make a backup

1. Open your server in the panel and go to Backups.
2. Press the backup button and give it a name, like before-nuclear.

It works while the server runs or sleeps. While it runs, the server saves the game first, so the backup has your latest work.

Restore a backup

1. Go to Backups and pick the backup you want.
2. Choose restore and confirm.

We make a fresh backup of the current state first, so a restore is never a one-way trip. The server then starts with the restored factory.

To go back only a few minutes, you can also load an autosave in the game. Sign in as admin, open Manage Saves, and load the save you want.

Download a backup

In Backups, choose download on any backup. You get a zip link that works for 24 hours. Inside are your .sav files, which you can load in single player or upload to another server.

Where your saves live on the server

Each save file belongs to a session, which is one factory. A session can have many saves, including its autosaves.

Bring your single-player factory

Find your save on your PC

On Windows, press Win + R, paste this and press Enter:

%LOCALAPPDATA%\FactoryGame\Saved\SaveGames\

Open the folder with a long number in its name. That’s your account. Steam and Epic each have their own number folder. Your saves are the .sav files, and the newest one is usually the one you want.

Playing on Steam Deck or Linux? The game runs through Proton, so the same folders sit inside Steam’s Proton files. The path is usually:

~/.steam/steam/steamapps/compatdata/526870/pfx/drive_c/users/steamuser/AppData/Local/FactoryGame/Saved/SaveGames/

The PS5 and Xbox versions can’t use dedicated servers, so console saves don’t come into this.

Upload it

Pick one of these three ways. The first is the easiest.

From the game (easiest):

1. Open the Server Manager, pick your server and sign in as admin.
2. Open Manage Saves and choose to upload a save.
3. Pick your save from the list. The game reads it from your PC.
4. When it finishes, load it.

From the panel:

1. Put your .sav file in a zip.
2. In the panel, go to Games > Bring your world and upload the zip.
3. We check it and put it in the right folder. Then load it from Manage Saves.

With Files or SFTP:

1. Stop the server from Overview.
2. Upload the .sav file to .config/Epic/FactoryGame/Saved/SaveGames/server/.
3. Start the server, sign in as admin, and load the save from Manage Saves.

After you load the new factory, check Auto-Load Session Name in Server Settings. It should name the session you want the server to open on each start.

Move from another server

Any Satisfactory server lets an admin download saves from the game itself.

1. In the Server Manager, sign in as admin on your old server.
2. Open Manage Saves and download the save you want. It lands in your PC’s save folder.
3. Sign in as admin on your new server and upload it from Manage Saves, then load it.

If your old server has a file manager instead, download the .sav files from its save folder. Then use any of the upload ways above.

Before risky changes

Make a backup by hand before a big game update, before adding a large mod, and before you rebuild something big. It takes seconds, and our automatic backups can only help with what they caught.
