📝 Notes

Duplicati runs a local web server on port 8200 by default — the UI is accessed via browser.
Backup configuration, schedules, and encryption keys are stored in %PROGRAMDATA%\Duplicati\ as SQLite databases and JSON files, not in the registry.
The service can be switched to run as a specific user account (not LocalSystem) for accessing network shares.
Duplicati also supports a "user-installed" mode without a Windows service — the tray icon launches the server on demand.

🗑️ Cleanup

Stop the service before removing registry entries:

Stop-Service Duplicati
sc.exe delete Duplicati
