Which directories should be mounted in docker to persist flows?

After having lost all my test work I decided it is time to investigate how to persist data in NiFi when running it in a docker image. I use the official image. This is what I managed to gather so far:

services: nifi: container_name: nifi image: apache/nifi:latest ports: - "8443:8443" - "16543:16543" volumes: - "C:/nifi/data:/data" - "C:/nifi/state:/opt/nifi/nifi-current/state" - "C:/nifi/database:/opt/nifi/nifi-current/database_repository" - "C:/nifi/flowfile:/opt/nifi/nifi-current/flowfile_repository" - "C:/nifi/content:/opt/nifi/nifi-current/content_repository" - "C:/nifi/provenance:/opt/nifi/nifi-current/provenance_repository"

When stopping/staring the container everything is OK (login credentials and content)

When removing the container, the credentials are persisted but the content is gone.

I presume that there is yet another directory that I should mount in order to have the data saved there. Which one is it?

Flow definitions are saved in the `conf` dir and at least 2 different approaches can be mentioned to backup it: the first by manually `docker cp`its contents and mount them later as a volume at your next run, while the second leveraging the mount bind option of docker to automatically synchronize the `conf` dir contents with your local dir.
