The service is responsible for performing backups and the restore, so you can disable the interface.
To disable the graphical interface in the client application, go to the application settings.
Then disable the options:
- Automatically run on system start,
- Log in automatically.
This will cause that during the system starts Xopero service will be started, while the interface will remain inactive. If you try to run the interface, the application will display a login screen where you will need to enter authorization data.
