Software, if you have BRMS it is easy to do, but expect your backup to take
probably twice as long and it will bury a small CPU. Also with any
encryption twice the amount of tapes that you are using now (Can't compress
the encrypted data like you would get from unencrypted data).
Hardware, is setup once and it's done. No slowdown in speed. Doesn't
require BRMS if you don't have it. Need Tivoli Life Cycle Key Manager to
setup. Can't do it on internal tapes, only external library attached SAS
(Power 6 & 7), or Fibre (Power 5, 6, and 7).
Let also not forget Key Management, and going to your Recovery site.

Subject: Backup Encryption on the i platform
I would like to solicit opinions on various methods of encrypting entire
backups on the I platform. The options I see are:
1) Hardware encryption
2) Software encryption
I am assuming that hardware would be easier to implement, but might be more
expensive, while software would be a little harder to implement, but might
be a little more lighter on the wallet.
Thoughts?
Thanks, Larry
