What is the specification of this large server? How many CPU's and
memory? What HBA's and how many of them do you have. How many network
cards are you using and how many are there?

Backup Encryption within Netbackup is a real performance killer!!!!

We tested this on a fairly large server.
Standard file level backup, using 10 LTO-3 tape drives and average speed
was 80MB per second per tape drive.

Next, turn on backup encryption for the exact same backup policy, start
the backup to the same 10 LTO-3 tape drives and we got an average speed
of 8MB (not a typo here folks....Eight) per second per tape drive.

It's best to go with LTO-4 tape drives and do hardware encryption of the
backup performance hit will smack you really hard.  [Shocked]
