Access to immich data from Portainer

Support and Troubleshooting
1

I’m trying to backup the immich directories to my NAS using a container.

ls -la /home/umbrel/umbrel/app-data/immich/data/upload works fine

from sudo docker run --rm -it -v /home/umbrel/umbrel/app-data/immich/data/upload:/data:ro alpine:3.19 I can see the directories

but if I create a stack which runs this script
version: “3.8”

services:
immich-backup:
image: alpine:3.19
container_name: immich-backup

command: >
  sh -c "
  apk add --no-cache rsync &&
  echo \"=== Immich backup started: $(date) ===\" &&
  echo \"DEBUG: /data contents:\" &&
  ls -la /data &&
  echo \"DEBUG: /data/library contents:\" &&
  ls -la /data/library
  "

volumes:
  - /home/umbrel/umbrel/app-data/immich/data/upload:/data:ro
  - /mnt/immich-backup:/backup

restart: "no"

I’m getting === Immich debug started: $(date) ===
DEBUG: /data contents
total 3
drwxr-xr-x 2 root root 1024 Jan 7 14:51 .
drwxr-xr-x 1 root root 1024 Jan 8 13:28 ..
DEBUG: /data/library contents
ls: /data/library: No such file or directory
/data/library not accessible

Can you help me on this?
