I tried that on a low end-system. Didn't see much improvement with the Gb-NIC. Sure, the nw-speeds were improved a bit, but not enough to warrant more work. OTOH it might be because the data we backup consists of many small files - this is slow. Jumbo frames may help, but I saw to many problems with this setting enabled. Finally I decided to just let it be and keep on as before.

However, my backup speeds to disk are not much better than to tape, but I was wondering if replacing the 10/100 NIC on the filer with a gigabit adapter might give me the extra throughput I am hoping for. Has anyone done anything similar or know for certain that a gigabit adapter would increase the backup/recovery rate? TIA
