You shouldn't expect that.  Different methods of file access and transfer=20
have different overheads.  For example, download a large FTP file from an=20
off-network location using Internet Explorer and then download the same=20
file using a standard FTP client like WS=5FFTP.  You'll usually see a marke=
d=20
difference.  Another comparison is to copy a very large file between=20
Windows machines using copy/paste from the GUI and then copy the same file =

using a utility like robocopy.  Windows file handling is notoriously=20
inefficient and slow.

If I can transfer a file using FTP=A0from my=A0Veritas server to a client a=
t=20
5000 KB/s should I get better than the 1200KB/s throughput I get from=20
NetBackup for my backups from that client?
