Don't it re-sync?

Thanks for your input.

I guess we should find out more definitely what the configuration is, as usn-policy is very Windows-tied.
What’s been posted here includes screenshots like Windows looking at the Unraid over SMB, however

makes me think Duplicati’s Docker container is on Unraid (which I think is based on Linux) with a more direct access path that doesn’t go over SMB but does have to get out of its Docker container to access requested source files. I don’t use Docker, but my impression is sometimes access needs to be set up.

What’s puzzling if it’s an access-to-host-files problem is that it seemingly did get to the initial four files…

FWIW

Any host directory that you want to back up needs to be mounted into the container using the -v option.

https://hub.docker.com/r/linuxserver/duplicati

    volumes:
      - </path/to/appdata/config>:/config
      - </path/to/backups>:/backups
      - </path/to/source>:/source

I have little idea how much help Unraid provides, but I saw an old video showing non-Duplicati screens.

How to install / configure a Duplicati Docker container (unRAID)

I use neither Unraid nor Docker, but any info on which Docker you got and how it’s hooked into Unraid?

and also use Unraid without ever using a command line? ls is like Windows dir command if you do that.

Does this happen on the current Beta 2.0.6.3? There were some fixes in 2020 that may or may not apply:

USN option working inconsistently

and I’m also not finding an open Issue that sounds like yours. Maybe you can open one if you know steps.
