UCP's RBAC system will manage authorizations, but it is true that it will also authenticate users if no external authorization source is configured or it is not available.
2. b and d: Docker provides a complete UCP backup and restore solution with the docker/ucp image, but remember that we should take care of Docker Swarm's filesystem because it is not part of UCP's backup. We should use the appropriate docker/ucp image release for our environment. In fact, we will use the same installed release for any action other than upgrading. UCP removal can be executed from the docker/ucp image and this will remove UCP components from all nodes in the cluster. We should then remove the docker/ucp image.
