Consolidation is done in the background before the backup starts so on restore, all of the data is restored with the single disk (vmdk file).
This is expected behavior.
Per the manual, vRanger uses VMware snapshot technology to temporarily store incoming write requests while the
source VM is being backed up. After the backup completes, the snapshot is deleted, which commits
those pending writes to disk. vRanger can backup a VM that already has an open snapshot and will
backup the open snapshot, but any secondary consolidated helper snapshots will be closed prior to
running the backup.
