Hello,
I am using amanda 2.4.4 and the amanda host (running RedHat 9) has a
gigabit connection to the network. Yet it seems to utilize only a
fraction of the available bandwidth. How do I force it to run at 100%
capacity? Here are the statistics from my last backup and below you can
see my amanda.conf file. Thanks in advance.
Ashwin Bijur.
