ndmpcopy copies data over the loopback device. If i remember right, loopback data is also accounted to network traffic in sysstat.

Hi,
When running ndmpcopy, copying data localy, on an idle machine, I notice that when running sysstat I see that while there is intensive disk activity there is also intensive network activity of similar magnitude.
I assumed that all the data would remain local on the netapp without any attempt of data going over the net.
Can someone explain.

Some ifstat -a data, taken at a few intervals, would show if the traffic's coming over a network interface, or the good ol' loopback interface.
