I would like to back up my nextcloud data using duplicati, but I absolutely can‘t figure out how to give Duplicati access to the Nextcloud volume. Both are running fine in separate Docker containers. I can’t figure out how to properly mount the volume, below is my current compose for duplicati. Do I need to mount the volume as source? Does it need to be declared or mapped separately?

version: "2.1"
services:
  duplicati:
    image: lscr.io/linuxserver/duplicati:latest
    container_name: duplicati
    environment:

      - PGID=1000

    You might try adding :rw after each of your volume paths, like this:

    volumes:
      - /path/to/appdata/config:/config:rw

    My honest suggestion would be to ditch Duplicati for Duplicacy. Duplicacy is one time payment, but it’s much more polished than Duplicati. I actually had major issues with recovering files from Duplicati; sometimes it would work and sometimes it wouldn’t. Not ideal for something as critical as backup software.
