Every amanda backup is a "network" backup.  I.e. client -> host.
That still uses part of the network stack I believe.

I'm on shakey ground here.  This is not a report of the current state, but
how things went during the run.  Seems like you would allow 4 dumpers max.
There were times when it could have gone to a second dumper but was
unable to do so.  The it gives the reasons, only one in yours, multiple
in Guy's report in the message that follows your in my mailer.

What do you have netusage set to?
