+> [!NOTE]
+> The default behavior of Velero will not recreate resources that already exist.
+> If the intention is to restore data on a PV, the PV/PVC will have to be deleted
+> before running the restore.
+
+> [!NOTE]
+> Additional configuration will be required to get CSI backed PVCs to be snapshotted
+> as noted in the [Velero documentation](https://velero.io/docs/main/csi/#prerequisites) - VolumeSnapshotLocation, VolumeSnapshotClass, etc.
+> as well as switching `snapshotVolume` to `true` in the backup config.
