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?=20

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. =20

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?
