Network data transfer rate is the rate when the client is actually sending the
data. Usually very close to the wire speed. Aggregate is amount of data
transferred divided by the backup's elapsed time. Not just the time the client
is actually moving data on the wire. If you don't see the network rate very
high (in the xx,xxx range) it can indicate a network problem.

Subject: [ADSM-L] network data transfer rate & aggregate data transfer rate
I have a question about aggregate data transfer rate. Why it is always a
lot slower than the network data transfer rate?
For example:
ANE4961I (Session: 18137, Node: MFDCITRIX) Total number of bytes
transferred: 13.61 GB (SESSION: 18137)
03/18/09 15:37:37 ANE4963I (Session: 18137, Node: MFDCITRIX) Data
transfer time: 914.17 sec (SESSION: 18137)
03/18/09 15:37:37 ANE4966I (Session: 18137, Node: MFDCITRIX) Network
data transfer rate: 15,618.11 KB/sec (SESSION: 18137)
03/18/09 15:37:37 ANE4967I (Session: 18137, Node: MFDCITRIX) Aggregate
data transfer rate: 2,220.91 KB/sec (SESSION: 18137)
03/18/09 15:37:37 ANE4968I (Session: 18137, Node: MFDCITRIX) Objects
compressed by: 14% (SESSION: 18137)
