velero-pvc-watcher is a Prometheus exporter that monitores all PVCs in the cluster and verifies that a matching backup.velero.io/backup-volumes or a backup.velero.io/backup-volumes-excludes is set.
Note: Due to the design all unmounted PVCs will reported as not being backuped, since there is no configuration for them.
