ICARUS (Dedicated Server) stores its config files at C:\Program Files (x86)\Steam\steamapps\common\Icarus Dedicated Server\Icarus\Saved\Config\WindowsServer on Windows. That folder holds the server rule set — multipliers, timers, slot counts and the admin list. Checkpoint64 already knows it, backs it up automatically and keeps earlier versions, so a config that got reset is one click from restored.
Where ICARUS (Dedicated Server) settings are stored

Backing up ICARUS (Dedicated Server) settings automatically
- Install Checkpoint64 (free) and pick ICARUS (Dedicated Server) — the config path above is already preset.
- Auto-backup watches the folder and uploads a new version whenever it changes, keeping full history.
- Restore any version in one click after a patch resets your settings, a file verification restores the defaults, or you move to a new PC.
