Duplicati and seeing folders in root folder

Running in docker compose on ubuntu gui.

I have a couple folders I need to backup but they live in the root folder. Can’t see them with duplicati even after adjusting some settings and such… wondering… do I just add them as volumes within the docker compose? seems so odd they don’t show up. everything else on the system appears to show.

Here is the docker compose I am trying to use. I was using the linuxserver duplicati version but have been attempting the same with the official release… is there any way to resolve this?

services:
  duplicati:
    image: duplicati/duplicati:latest
    container_name: duplicati
    environment:
      - PUID=0
      - PGID=0
      - TZ=America/Chicago
      - CLI_ARGS= #optional
    volumes:
      - /appdata/duplicati/data:/data
      - /mnt/backup:/backups
      - /:/source
    ports:
      - 8201:8200
    restart: unless-stopped

did you try to enter the container and to do a

ls /source -lart

and to compare with the command

sudo ls / -lart

on the host ?
