 * Is it backed up?
-To more accurately implement this use-case, Kubernetes has two object types called PersistentVolume and PersistentVolumeClaim.
+To more accurately implement this use-case, Kubernetes has two object types called [https://kubernetes.io/docs/concepts/storage/persistent-volumes/ PersistentVolume and PersistentVolumeClaim]. The idea is that a cluster administrator creates PersistentVolumes (abbreviated <code>pv</code>) that know what kind of storage they represent and where to find it; then, users create PersistentVolumeClaim (abbreviated <code>pvc</code>) asking for storage with constraints like "at least 10 GB". When a PVC is created, it is matched to its closest PV and a link is created. If no PV is available to fulfill a PVC, the PVC stays in "Pending" state. In a way, PersistentVolumes are like Nodes in the sense that they provide capacity, and PersistentVolumeClaims are like Pods in the sense that they use that capacity if it is available anywhere in the cluster.
