velero restore create failed to restore pv only

[jhuisss]

Describe the bug

I installed velero 1.9.2 and use velero-plugin-for-vsphere to handle pv backup and restore. But velero restore create failed to restore pv only.

To Reproduce [Steps to reproduce the behavior]

# kubectl get pv
NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS   CLAIM                      STORAGECLASS   REASON   AGE

Here the msg "Persistent volume is not a supported volume type for snapshots, skipping." is pretty weird, is this expected?

Then I forced remove the pv from the workload cluster:

# kubectl get pv
No resources found

# kubectl get pvc -A
NAMESPACE       NAME         STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE

Then I try to restore the pv from the backup:

# velero restore create --from-backup backup-pv-2
# velero restore describe backup-pv-2-20221028094736

But the pv did't show up:

# kubectl get pv
No resources found
# kubectl get pvc -A
NAMESPACE       NAME         STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE

Expected behavior

The pv should be restored.
