You are working on a Kubernetes cluster that hosts a logging system. The logging system uses Persistent Volumes (PV) to store logs, which must be retained even if the logging Pods are deleted. You also want to ensure that if the application is deleted, the data remains accessible for future use, but the volume should not be automatically reused by other applications. Which of the following volume reclaim policies would best meet the requirement of preserving the data after the Pods and application are deleted?
