I'd recommend looking at tuning but also you're not specifying the devices
on both ends.

Are you ftp-ing disk-to-disk but testing NB with disk-to-tape?  There's
obvious issues that that scenario.

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?
