At the advent of containers, users were primarily using containers in a stateless manner. As adoption grew, Kubernetes clusters started using stateful containers. Containers have two types of data: Business Data and Metadata. A stateful container has both business data and metadata, whereas a stateless container has only metadata. Metadata can be extremely important as well and needs protection too. Metadata controls how the container deploys, how it scales, what attributes it uses, what keys it uses, and so on. Metadata is critical for reinstating the application and is equally important to protect against engineered or natural disasters. Metadata is needed for true application recovery.
