Hello,
I just upgraded our main file server with a larger hard disk and a faster network connection. I also added a gigabit network card to our Backup Exec 9.1 server. Both of these computers are plugged into the same gigabit switch, and the switch management shows both systems connected at 1000/full.
However, during the nightly backups, the backup speed averages about 130 MB/Minute. According to the specs on our tape drive, it should be backing up at at least 35 MB/Sec (or 2.1 GB/Hour). And these are the low-end specs.
I have tried backing up large files on the local backup system to see if it was a network issue, but it runs at the same speed. It is getting to the point where the backup barely finishes verifying from the night before when it is time to leave for the night. (The full backup/verification of about 83 GB of data takes around 19.5 hours).
Our tape drive is a Dell 110T LTO-2. We are running Backup Exec 9.1 on an XP SP2 station. Backup Exec is the only application we run on this computer. I have upgraded to the latest drivers from Dell, but this did not help.
Please tell me if I am overlooking something obvious, but the way I see it, our entire network should only take less than an hour to back up, and then probably the same amount of time to verify.
