Hi Andrea, hope you are doing fine, I'm seeing in the customer case a base name `volume-<vol-uuid>.backup.base`. On the description says that the steps to reproduce are: 1.cinder backup-create <unattached volume uuid from NFS backend> and 2.cinder backup-restore <created back uuid> --name <testrestoredvolume> . However, just to double check: Do you know if the backup was created from a Cinder snapshot? (i.e. using: cinder backup-create <volume-uuid> --snapshot-id <snapshot-uuid>) Cheers, Sofia
