If you need to do both, then your best best is to COMPRESS via
Networker, then use a hardware-based encrypting tape drive(s) to
ENCRYPT the data on tape.
I would say that using a tape drive to to both the encryption and the
compression is better still. The LTO-4 can give extremely good
compression at the same time as encrypting.
I know that opinion differs on this list, but I believe that
compression
at the client level should only be done in the case of a slow network
connection, and only then if the client has sufficient spare CPU
capacity.
Last time I checked, Networker still has no built-in mechanism to do
key management. You have to purchase a separate (third-party?) product
(unlike NetBackup (6.5.2), which has had it for a year now).
So if you want to secure your data, the only way to currently do it--
using just Networker--is to encrypt it at the client.
