pb performance HP ultiurm 2-SCSI

Hi,
on win2k3, with backupexec9.1 and tape drive HP ultrium2, have performance pb.
Have to backup 400Go and it takes more than 20 hours...
theoric rate is 24Mo/s, so backup should take only 5~6 hours.
I test with LTT tools the performance and assume that it is not a hardware pb, we are near the theoric transfert time( use variable block size option)
In backupexec, the config for the drive is set as followed :
block size=64ko
buffer size=64ko
number of buffer=10
high number of buffer=0

what is the recommandation for this type of drive with backupexec ?

You must have Symantec drivers on the tape drive. Also upgrade to latest driver on your HBA.
