Bobby,

You may also want to check if your NIC on windows server is throttled down 
by Windows by default.  I have heard about this that Windows by default will 
throttle down to some very low throughput.  Please check further into it.

        I'm curious to hear what kind of speeds (mbs/sec) others are
getting backing up windows servers.

        Running Netbackup Enterprise 5.1 mp6 under Solaris10 on
master/media servers.

                a.        Using brocade 2g ports 48000 director.
                b.        IBM Ultrium LTO Gen2 drives
                c.        Sun branded Qlogic 2gb cards. single port
feeding each tape drive.
                d.        The storage on the windows servers is FC
attached Hitachi Tagmastore 9990.  (Very fast drive configuration.)
                e.         Servers are HP G5's also 64 bit. Some are 32
bit. Seems 32 bit servers are actually faster.

        note:         Some of my other backups such as Solaris, Linix
and Netware can get as much as 20 mb/sec with this configuration.
                So why are the windows servers so slow? Any  one have
some kind of idea what may be a cause?  Or it is what it is!  Windows!
