Sree - Almost.  The 20th field of the accounting record is Session KB:
       Amount of data, in kilobytes, communicated between the client node and
the server, in both directions, during the session, including session overhead
data as well as storage pool data. The number corresponds to message ANE4961I
total bytes transferred.

Field 17 is the pure backup data value.
