Very slow LTO3 with Backup Exec 12.5
We just bought a new LTO3 lib with a HP drive. For any reason backing up is very slow, it starts fast but within a minute the speed is down to about 10MB/min. All firmwares for hardware are latest and drivers as well.
I have tried with MS, vendor and Backup Exec drivers for the LTO3, same issue whatever driver i choose. Our old Sony lib (AIT3) works on this hardware. I have changed SCSI card (same model), scsi cable
and terminator, still no luck.
Just so i could exlude my thoughts that the drive could be broken, i've tried another backup software. I've downloaded a trial fom ARCServe, and guess what....that did it. I got avarage speed just over 1700MB/min.
It seems that Backup Exec is the issue.
Its there any unofficial patch for this? SP3 and else patches for 12.5 did not solve my problem.
