what's the use case for backing up running containers? the code in the docker image is immutable (or should be), config goes into .env file and permanent data should go to a mounted volume in the host or an external database, so what do you want to backup?

      I do, and use the same tooling for Postgres containers as when running Postgres outwith containers - WAL-E.
