How to validate backup and restore processes in Ballerina applications?

When working with Ballerina services that persist state or rely on external data stores, ensuring that backup and restore operations are correct is important for reliability. What steps, tools, or practices can be used to verify that a backup captures the necessary state and that a subsequent restore returns the service to a known good condition? Please outline any built‑in Ballerina features, recommended patterns, or external approaches that support this validation.
