Need help using WinRAR on PR4100 with Docker


I’m trying to do a complete backup of PLEX using WinRAR.

I’m using My Cloud OS 3 (Firmware 2.31.204) with its stock version of Docker.
This will be the first time I ever use Docker.

So I ran these commands via SSH:

docker pull klutchell/rar

docker images to get the ID of the image.

docker run (ID) and saw WinRAR’s list of commands and such.

Now how do I RAR the files and folders from “/mnt/HD/HD_a2/Nas_Prog/plex_conf” to an external drive I have mounted “/mnt/USB/USB1_e1” using Docker?
