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.
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.
Part of me thinks the real issue is compression isn't actually working. Though the compression setting in the jobs are available to set, I get hardly any compression whether I choose hardware or software. It looks to be only 1.02:1 which is ridiculous to me. 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).
