Newbie in need of help for backup

Instead of a bind mount, just do a standard volume mount. An example from my docker.

Code:

volumes:
      - ./jellyfin-data/config:/config
      - ./jellyfin-data/cache:/cache
      - /media/library:/media/library:ro
      - /media/storage2:/media/testLibrary:ro
