Backups take too long any help

[Mo_Borhot]

Im new to the whole backupexec environment and hoping someone can help speed up my backups. Im using backup exec 9.1 with an hp 1/8 autoloader.
Byte count : 126,209,031,690 bytesJob rate : 125.00 MB/Min (Byte count divided by Elapsed time for job)
Which takes 30:34:08
Any Ideas on speeding this up ?

Local or network backups? or both?
Exactly what kind of drive is it?
What are the settings for the drive for buffers?

[Mo_Borhot]

the data is being backup from local SCSI drives.

What are the setting for buffers for the device?
Any overnight maintenence that my be conflicting? (Virus Scan, Defrag, etc)

[Mo_Borhot]

how would I go about finding the buffer setting for the device ? really sorry I did say I was new to all this and im just trying to speed things up im not sure if it will be possible as I was told it isnt by the person who is use to take care of the backups he said it has to do with the SCSI bus would timeoutif the speed was set too high and the backs would fail but I thought I would go furthur to see if is is normal for 126 gig to take 30 hours. Thanks again

125Mb/min isn't bad, but by no means as fast as some

From the devices tab, right click the drive\Properties
Id the drive the only thing on this controller? or at least the only device on this channel of this controller?
