Reinstall 7 Days to Die Server Without Losing World

This guide walks you through reinstalling a 7 Days to Die dedicated server while keeping your world, player data, and settings intact. You’ll back up the essential files, reinstall the server software, and restore your data—so your survivors and builds survive the process.

What You’ll Need

  • Access to your server’s file system (via FTP, SSH, or the hosting provider’s file manager)
  • Your server’s current save files location (usually SaveGame folder inside the server directory)
  • A backup destination with enough space (local drive, cloud storage, or another directory)
  • The ability to stop and start the server (control panel or command line)
  • If using SteamCMD, the server’s App ID (294420) and your Steam credentials (or anonymous login if allowed)

Step-by-Step

  1. Stop the server. Use your control panel or send a shutdown command. Wait until the process fully exits—do not skip this, as it ensures all data is written to disk.
  2. Locate your world and player data. In the server folder, find the SaveGame directory. Inside, you’ll see a subfolder named after your world (e.g., My Game). This contains the world map, player data, and server settings. Also note the serverconfig.xml file—it holds your game settings, mods, and admin list.
  3. Back up everything important. Copy the entire SaveGame folder and serverconfig.xml to a safe location outside the server directory. If you use mods, back up the Mods folder and any custom XML files in the Data folder. Double-check the backup by listing its contents.
  4. Remove or rename the old server files. To avoid conflicts, either delete the entire server directory or rename it (e.g., 7dtd-server-old). If you’re using a hosting panel, use its reinstall option instead—this often handles cleanup automatically.
  5. Install a fresh copy of the server. Use SteamCMD to download the latest dedicated server files. Run steamcmd +login anonymous +force_install_dir ./7dtd-server +app_update 294420 validate +quit. If you’re on a hosting panel, use its install/update button.
  6. Copy your backup back. Place the backed-up SaveGame folder into the new server directory, exactly where it was before (e.g., /7dtd-server/SaveGame/). Also copy serverconfig.xml to the root of the new server folder. If you had mods, copy the Mods folder and any custom XML files back.
  7. Verify file permissions. On Linux, ensure the server user can read/write the restored files. Run chown -R serveruser:servergroup /path/to/7dtd-server and chmod -R u+rwX /path/to/7dtd-server.
  8. Start the server. Launch it via your control panel or command line. Watch the console for errors. If it starts without issues, your world should load with all player data intact.
  9. Test the connection. Join the server from the game client to confirm you can spawn in the correct world and that your character and inventory are present.

Common Mistakes

  • Not stopping the server before copying. Copying while the server is running can corrupt the save. Always stop it first.
  • Only backing up the map file. The world is more than just map.png—you need the entire SaveGame folder, including players.xml, stats.xml, and region files.
  • Overwriting the new server’s settings with old ones that reference missing mods. If your old serverconfig.xml includes mods that aren’t installed, the server may fail to start. Reinstall mods or edit the config accordingly.
  • Placing files in the wrong location. The SaveGame folder must be in the same relative path as before. For example, if it was under 7dtd-server/SaveGame, don’t put it under 7dtd-server/Data/SaveGame.
  • Skipping the validate step in SteamCMD. Without validate, corrupted files may persist, leading to crashes later.

Tips

  • Make a second backup. Keep one backup on the server (in a different folder) and one off-server (local or cloud). This protects against hardware failure.
  • Use a naming convention. Name backups with the date, e.g., SaveGame-backup-2025-04-10. This makes it easy to roll back if needed.
  • Test the backup before reinstalling. If possible, run a temporary server from the backup on a different port to confirm it loads. This catches issues early.
  • Keep a copy of your mods. Even if you don’t use them, store them separately so you can reinstall them quickly.
  • Note your server’s port and settings. Write down the game port, query port, and any custom settings so you can verify they’re correct after reinstall.

Troubleshooting

  • Server fails to start after restore. Check the console for errors. Common issues: missing mods, incorrect file permissions, or a corrupted save. Try starting with a clean serverconfig.xml to see if the save loads; if it does, your config is the problem.
  • World loads but players are missing. Ensure you copied the players.xml and stats.xml files. If they’re missing, restore from a backup or accept that player data is lost.
  • Server starts but crashes when a player joins. This often indicates a corrupted region file. Try deleting the Region folder inside your world (this resets the map but keeps player data). If that works, you can use a map editor to recover chunks.
  • SteamCMD fails to download. Run steamcmd +login anonymous +force_install_dir ./7dtd-server +app_update 294420 validate +quit again. If it persists, check your internet connection or firewall—SteamCMD needs access to Steam’s servers.
  • File permissions errors on Linux. Use ls -l to check ownership. The server process must have read/write access to the SaveGame folder and its contents.

Frequently Asked Questions

Will I lose my character and inventory?

No, as long as you back up the SaveGame folder, which contains players.xml and stats.xml. These store character data, inventory, and skills.

Do I need to back up the entire server folder?

No, only the SaveGame folder, serverconfig.xml, and any mods/custom files. The rest is the server software, which you’re reinstalling fresh.

Can I reinstall without SteamCMD?

Yes, if you’re using a hosting provider, they usually have a one-click reinstall. If you’re on your own machine, you can download the server files from the 7 Days to Die official website or use Steam’s client to install the dedicated server tool.

What if my backup is corrupted?

If your backup is corrupt, you may have to start a new world. To avoid this, always stop the server before copying and consider using a tool like 7-Zip to compress the backup—this can help detect errors.

Will my server settings (like difficulty or mods) be preserved?

Yes, if you restore serverconfig.xml and the Mods folder. However, if a mod is outdated, it might cause issues; you may need to update mods to match the new server version.

How long does the reinstall take?

Downloading the server files via SteamCMD typically takes 5-15 minutes depending on your connection. Restoring the backup is quick, but the whole process could take 30 minutes to an hour including testing.
