How to Update Your SCUM Server

Last updated: September 18, 2026

SCUM receives regular updates, and your server needs the matching version so that updated clients can join. This guide shows you how to update your server while keeping your config and save.

Step 1: Back Up Your Files

Download copies of these from the server before updating, so nothing is lost if an update replaces a file:

  • SCUM/Saved/Config/WindowsServer/ - ServerSettings.ini and your admin and ban lists.
  • SCUM/Saved/SaveFiles/ - your world, including SCUM.db, SCUM.db-wal, and SCUM.db-shm.

Step 2: Update the Server

  1. Log in to the NolimitHost Game Panel, select your SCUM server, and stop it from the Console page.
  2. Go to Configuration > Advanced > Reinstall Server to re-run the installer, which validates and updates the server files to the latest build.
  3. Start the server again and check the console for the reported version.

Updating on a VPS

If you run the server yourself, update it with SteamCMD using the SCUM dedicated server App ID 3792580:

steamcmd +force_install_dir /path/to/server +login anonymous +app_update 3792580 validate +quit

Run it from the same install directory you used originally so the update lands in the right place.

Note: 3792580 is the free dedicated server. The paid game client is 513710. Do not mix them up.
Important: If a SteamCMD update fails silently on a self-hosted server, delete the appmanifest_3792580.acf file from the steamapps/ folder and retry. Back up your Saved/ folder first so a reinstall cannot touch your world.

Step 3: Check Your Server After Updating

  • Confirm ServerSettings.ini is still present with your settings. Restore it from your backup if it was reset.
  • Confirm your admin lists in SCUM/Saved/Config/WindowsServer/ are intact.
  • Check that your save loaded correctly by joining the server. See Connect to Your Server.
Tip: After a major update, some config keys move or change. Compare your ServerSettings.ini with a freshly generated one and re-apply anything that changed. See Configure Your Server.
