[Help] Backing up Nextcloud with Duplicati (Docker) (self.selfhosted)

submitted 1 year ago by avnrt to c/selfhosted

16 comments fedilink hide all child comments

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

Thanks! A drop down chevron has appeared next to the "Source Data" folder in duplicati, but it is still empty, showing neither the volume, nor its contents. Any idea what else I can try/modify?

Does it show the root / filesystem inside the container?

You may need to update the folder permissions on the Nextcloud volume to allow all users to read data.

I do see the entire filesystem, and now also the volume, but can't access it.

I would suspect permissions, make sure the volume is set to allow all users to read from it

Yeah really seems most likely. I'll start poking around permissions, thanks
