I am having major issue with my backup over a month now. It was working find before where it would do 3 to 3.5 GB/min and all of a sudden the speed dropped in half. I have called Quantum, they shipped me brand new Quantum Superloader3 Tape Library with Cable and Terminator. I have bought a brand new Adaptec 29320A-R card with non raid drivers installed per quantum. I cannot get the speed on the backups now. Before the backup would start at about 4gb/min and it will adjust accrodingly to like 3, 3.2, or 3.5 GB/min. Now it will start slow and then it will go up as far as 1994.00mb/min and starts to drop and stay around 800mb/min. I have been through all over the web, cannot find anything that would fix this issue.
Any help would be greatly appreciated
