The default Duplicati architecture for both service and non-service is a parent process that runs from the installation (e.g. C:\Program Files\Duplicati 2), looks for installed updates, and starts the latest as a child.
Activate button exits the child with an MAGIC\_EXIT\_CODE that gets parent to restart on the newer install.

Good to hear. Thanks. In terms of availability, it’s “supposed” to be a small outage, then back up on new…
Non-Windows systems are basically paired Duplicati processes, plus something above, maybe systemd.
Windows systems have [Duplicati.WindowsService.exe](https://duplicati.readthedocs.io/en/latest/07-other-command-line-utilities/#duplicatiwindowsserviceexe) in the mix. A maximum view (and more) is at link:
[[SOLVED] Is it ok that I see 5 processes of Duplicati in Windows Task manager?](https://forum.duplicati.com/t/solved-is-it-ok-that-i-see-5-processes-of-duplicati-in-windows-task-manager/3948)
In both Windows and Linux there’s OS administrator level control (services.msc, systemctl, etc. ) needed to totally take down the service, but there’s also the hopefully-short outage when Duplicati runs the update.
