What's your client & file distribution.  WinNT is notorious for being slow
when doing 1000's of small files as opposed to fewer, larger files.  
 
I'd play with the buffering & tuning.  Make sure to modify both client &
media server when you do so.

Tape drive:SDLT scsi
Network:1Gig.
For testing purposes there are no additional clients performing a backup at
the time
The client and server are Dell 4way Pent. 4 servers with gig Ethernet
interfaces.

What are you using for your tape devices?  How are they connected?  What is
the network speed to the Media Server?  Are there multple clients being
backed up to this media server at the same time?

But should the differences be that large?  I have another client that will
ftp to the Veritas server at 15,000KB/s but the Veritas backup is 1000KB/s.

You shouldn't expect that.  Different methods of file access and transfer
have different overheads.  For example, download a large FTP file from an
off-network location using Internet Explorer and then download the same file
using a standard FTP client like WS_FTP.  You'll usually see a marked
difference.  Another comparison is to copy a very large file between Windows
machines using copy/paste from the GUI and then copy the same file using a
utility like robocopy.  Windows file handling is notoriously inefficient and
slow.

If I can transfer a file using FTP from my Veritas server to a client at
5000 KB/s should I get better than the 1200KB/s throughput I get from
NetBackup for my backups from that client?
