Why each option
The 'Retain' reclamation policy for a PersistentVolumeClaim (PVC) ensures that the underlying PersistentVolume (PV) and its data are preserved upon PVC deletion.
claimRef is a field within a PersistentVolume object that points to its bound PersistentVolumeClaim, not a reclamation policy.
The 'Delete' reclamation policy automatically deletes the underlying PersistentVolume and its data when the bound PersistentVolumeClaim is deleted.
When a PersistentVolume is configured with the 'Retain' reclamation policy, deleting the associated PersistentVolumeClaim (PVC) does not automatically delete the underlying physical volume or its data. Instead, the PV enters a 'Released' state, allowing administrators to manually recover or reuse the data.
The 'Recycle' reclamation policy is deprecated and has been replaced by dynamic provisioning or the 'Retain' policy for data safety.
