It appears the GUI is generating CLI commands. Is that correct? If so, is it possible to capture those commands for future use?
The GUI just invokes the CLI version to run backup and prune. You can find all those commands in the log.
Is the Windows scheduling feature inherit in the GUI deployment or can I set up and modify scheduled jobs via the CLI? Wasn’t clear on if the Windows service was a GUI-only component.
The GUI version implements its own scheduler – you need to let it keep running to start scheduled backups. The GUI version can also register itself as the Windows service (in other words, when you start the Duplicacy service, it is just another instance of the GUI version running in service mode).
You can also use the Windows Task Scheduler to set up scheduled jobs with the CLI version. I’ve done it myself but it should be fairly easy.
