I had to re-install windows 2008 32bit on my server to fix iSCSI issues I was having. I then re-installed Backup Exec 12.5, Sp3 and all patches. Disk backups work fine, but the weekly tape that picks up from disk has dropped from 1,500mb/min to 5mb/min! Symantec support has been useless...we've re-installed the Adaptec Ultra 320 drivers, tried both the updated symantec and HP drivers for the tape drive...nothing seems to help...very frustrating. Fix one issue and break something else. It has to be a driver issue or software setting since none of the hardware has changed. Robotic library is an Arcvault 24 LTO4. Connected via SCSI cable, running backups locally on the media server where our disk backups are stored, so no network involvement.
