Hello!

We have a problem with cinder-backup with cephbackup driver and volume on purestorage. When backing up purestorage volume with cinder-backup with cephbackup driver it creates in ceph pool and everything is ok. But when we try to restore the backup, it is not restored with an error "rbd.ImageNotFound" in the screenshot attached to this email. This happens because the original image is not in rbd, it is in purestorage. It is not clear why the cinder is trying to look for a disk in the ceph. Could you please help with this?

Thanks. Regards.
