Is there a way to back up existing PVs and PVCs and then create new PVs and PVCs by simply changing their names?

Hello, We are conducting various tests to introduce Bellero.

Client:
        Version: v1.12.1
        Git commit: 5c4fdfe147357ec7b908339f4516cd96d6b97c61
Server:
        Version: v1.12.1

As the title suggests, the current PV and PVC have been properly backed up.

NAME    STATUS      ERRORS   WARNINGS   CREATED                         EXPIRES   STORAGE LOCATION   SELECTOR
mysql   Completed   0        0          2023-11-09 14:34:12 +0900 KST   25d       default            app=mysql

Afterwards, we confirmed that it was restored normally after deletion.
I also confirmed that it can be restored by changing the name through the --resource-modifier-configmap plugin.

#restore_config.yaml

version: v1
resourceModifierRules:
- conditions:
    groupResource: persistentvolumeclaims
    labelSelector:
      matchLabels:
        app: mysql
  patches:
  - operation: replace
    path: "/metadata/name"
    value: "pvc3" 
  - operation: replace
    path: "/spec/volumeName"
    value: "pvc3-pv" 

- conditions:
    groupResource: persistentvolumes
    labelSelector:
      matchLabels:
        app: mysql
  patches:
  - operation: replace
    path: "/metadata/name"
    value: "pvc3-pv"
  - operation: replace
    path: "/spec/claimRef/name"
    value: "pvc3"

Now, if an existing PV and PVC exists and you rename it and then try to create a new PV and PVC, you will see a warning.

If there is a way, please share.
Or...is it not functional in the first place?
