            Adding a disk during a backup is not recommended, as the current
            disks list could be inaccurate. It will pull the informations
            about the current disks attached to the domain, but the backup
            process creates temporary external snapshots, changing the current
            disks attached. This should not be an issue when the backingStore
            property will be correctly handled, but for now it is.

        :param dev_disk: dev name of the new disk to backup. If not indicated,
                         will add all disks.
