I just got the Duplicati installed and started working on it in less than 2hrs. It is a genuinely athletic build, and I adore it as a personal cloud owner. May I ask what kind of action will stop it from working? Such as should I keep the browser tab up to keep it working, or it’s not necessary at all?
The browser does not need to stay open. It simply shows you the state of the backup engine.
If you did a default install, Duplicati runs as a regular user process under your login. As such, logging out would cause the backup engine to stop.
If you right-click on the tray icon and choose Quit, it will cause the backup engine to stop as well.
