How can I backup all datas of Rasa x?

Hello! I am a newbi for Rasa framework. I launched Rasa X by Helm chart. It works great. But I’m a newbi on Helm chart too, so I don’t know how to backup all data of Rasa X that stored in RabbitMQ, Redis, PostgreSql and etc. If it was docker-compose, I can use volumes for backuping files. However there is not any tag like volumes in value.yml in Helm chart. I attached my values.yml below. That is just purely default one. Thanks for you in advance.

rasax:
    initialUser:
        password: "password"
    passwordSalt: "salt"
    token: "rasax_token"
    jwtSecret: "jwt"
    tag: "0.35.1"
rasa:
    token: "rasa_token"
    tag: "2.2.9-full"
rabbitmq:
    rabbitmq:
        password: "rabbitmq_password"
global:
    postgresql:
        postgresqlPassword: "postgresql_password"
    redis:
        password: "redis_password"

The recommendation is to connect your Rasa X instance to a git repo which is discussed here. The git repo gives you the backup of your training and configuration.

thank you for your advice!
