Re: BRMS

Larry:

The LTO can do the encryption at the tape level, but it requires a Fibre attached tape, SCSI attached tapes cannot do encryption at the device level due to the specification of the Fibre vs. SCSI interface for LTO (remember that is an industry standard, not an IBM one). The implementation is not really all that difficult but planning for a recovery is somewhat more involved since you have to have the keystore available as well as the exact same tape technology. Managing the keys is the most difficult part of the process. You need to plan your recovery first, the build the back up strategy to support the recovery.

You need the advanced portion of BRMS for the software encryption. As Pete indicated it can be a bit slow if there is not sufficient CPU/Memory available to to the back up. Even if there is it will be slower than just writing to tape directly.

Pete,
Have you actually used the LTO tape drive hardware encryption? Is
it easy to implement? I would imagine it is easier than software. Do you
have software keys to admin with the tape drive based encryption? How may
questions can I ask in this paragraph?

thanks, Larry

BRMS has an OPTIONAL software encryption component, it will be much slower
than hardware encryption.

Hello group,
I've not used BRMS in many years and I have a question. I've been
told that BRMS does encryption for backups. Is this true, and if so, does
it do it through the software or just control the encryption to the tape
drive that would do it?

thanks, Larry
