but I wouldn’t guarantee that its omission is for security reasons. How do you feel about program restart? That’s currently tried during upgrades. Beta Update never gets to activate on Linux shows it’s not reliable.
Possibly it will be replaced, however the security aspects might change. Currently the autoupdater has a design-intent capability to update Duplicati without administrator privilege. I’m not sure the future way will.
Duplicati as a service - more complicate than it need be is another discussion of services and their risks.
What OS? Is Duplicati having an issue?
