Sorry , I mean use the NFS driver as the cinder-backup_driver.I see the
remotefs code achieve the create_volume_from snapshot[1],in this function the
snapshot.status must be available. But before this in the api part, the
snapshot.status was changed to the backing_up status[2].Is there something
wrong?Can you tell me more about this?Thank you very much.

create_volume_from_snapshot is implemented in the NFS driver. It is in
the remotefs code that the NFS driver inherits from.
But, I'm not sure I understand what's being asked here -- how is this
related to using NFS as the backup backend?
