# Reclaim PVs

NebulaGraph Operator uses PVs (Persistent Volumes) and PVCs (Persistent Volume Claims) to store persistent data. If you accidentally deletes a NebulaGraph cluster, PV and PVC objects and the relevant data will be retained to ensure data security.
NebulaGraph Operator uses PVs (Persistent Volumes) and PVCs (Persistent Volume Claims) to store persistent data. If you accidentally deletes a NebulaGraph cluster, by default, PV and PVC objects and the relevant data will be retained to ensure data security.

You can define whether to reclaim PVs or not in the configuration file of the cluster's CR instance with the parameter `enablePVReclaim`.

If you need to release a graph space and retain the relevant data, update your nebula cluster by setting the parameter `enablePVReclaim` to `true`.
You can also define the automatic deletion of PVCs to release data by setting the parameter `spec.enablePVReclaim` to `true` in the configuration file of the cluster instance. As for whether PV will be deleted automatically after PVC is deleted, you need to customize the PV reclaim policy. See [reclaimPolicy in StorageClass](https://kubernetes.io/docs/concepts/storage/storage-classes/#reclaim-policy) and [PV Reclaiming](https://kubernetes.io/docs/concepts/storage/persistent-volumes/#reclaiming) for details.
