If you need to go back in time and restore a previous save, ARK automatically creates backups overtime that you can use to restore you save. To do so, you can follow these steps.
1. Open the File Manager
2. Navigate to /steamcmd/ark/ShooterGame/Saved/SavedArks/
3. In this folder, your current save is <mapname>.ark
. The backups are the dated files with the map name, such as <mapname>.15.03.2024.11.49.39.ark
. To restore a backup, simply rename one of these files to <mapname>.ark
. Replace the existing one.
4. Once you've renamed your chosen backup, Restart the server.
