I recently went from our old backup using a Dell LTO1 Ultrium 1-SCSI single drive and upgraded to a robotic library Exabyte Magnum 1x7 Autoloader. (It resides on a dedicated Raid Controller from hard drive).
When I initially installed the drive, I used the Windows driver and it loaded. The backup went quickly and fast as I expected. I then uninstalled that driver and installed the Veritas driver so it will work with my BE software. I used the following driver: http://seer.support.veritas.com/docs/273853.htm. It seemed to install correctly, BE sees the device as an robotic library and it will work. However, it is incrediably slow. Slower than the old Dell tape drive I had. I cannot get it to backup local files above 130.00 MB/min. When using the Windows driver I was getting speeds at 1,743 MB/min.
I really want the speed back that I know the device is capable of...is there anything I can do to speed it up? I have already tried unchecking Read single block (in the drive's configuration) and turning off Anti-virus.
I am using a Windows Server 2000 on a NTFS format with Vertias Backup Exec 9.1 with what I have found to be the latest patch (unless I missed one). The hardware is a Dell Poweredge 2650 running dual P4 3.0, 2 GB memory, 139 GB RAID 5. Again, the thing that disappoints me is I got faster backup time on the much older Dell LTO tape drive. This drive is capable of much faster speeds which I got using the Windows driver. Is there a more updated Veritas driver?
