The backup job always backs-up only the current guest-visible state of the disks. Technically a snapshot is a point-in-time in the past you might want to return to. The state represented by the snapshot is thus different from what you are backing up. With external snapshots the backup will be identical as if you merged in all the layers created by the snapshots.
