Restore Stalled in "InProgress" state

[wcochran53]

I done a backup of a namespace with velero using restic.
The storage class for the PVC was a custom storage class making use of an installed csi.
The backup was taken successfully and the object details and restic data stored in the S3 backup location.
I then restored this backup onto a different cluster which was using a different storage class. The restore stalled (remained "InProgress") because the restored PVC was in "pending" state because the storage class that was restored didn't exist on the cluster.
I have been able to correct this issue by deleting the PVC and remaking it with the correct storage class for the cluster I am restoring onto.

However what I am wondering is whether
(1) is there any mechanism for timing out the restore or avoiding this happening in the first place
(2) if a restore does get stuck in the "InProgress" state does it prevent further backups/restores from being actioned?

Kuberenetes version 1.18
