After an upgrade to 5.1.6.0 from 4.2.0.0 the result from: 
select entity,sum(bytes) from summary where (activity='BACKUP' or
activity='ARCHIVE') and cast((current_timestamp-end_time)hours as
decimal)<24 group by entity
is different, most nodes shows 0 bytes, when I ran 4.2.0.0 no nodes showed 0
bytes.
