[Help] Backing up Nextcloud with Duplicati (Docker) (lemmy.world)

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:
      - PUID=1000
      - PGID=1000
      - TZ=XXX
      - CLI_ARGS= #optional
    volumes:
      - /path/to/appdata/config:/config
      - /path/to/backups:/backups
      - /path/to/source:/var/lib/docker/volumes/073ac2751cd65ffd84750e578c38482905c3c7e4851a8cbb0bbbc5c33a285e84
    ports:
      - 8200:8200
    restart: unless-stopped

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.

I'll take a look at Duplicacy, thanks
