Dennis,

Was this with MSEO (Media Server Encryption Option) of client side
encryption?

Thanks,

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]
