Здравствуйте,

We have installed dedicated GbE network card into Domino server and take
advantage of multistream backup by using NEW_STREAM directive. Every stream
goes to its respective tape drive. So overall backup spead is about 50-60
Mb/s. Network card utilization is about 80%. That looks great!
