RE: IBM Efforts to Introduce Encryption Method for Tape Save

You should have the option to create a certificate with DCM to encrypt
the tapes.  You can take this to a DR box and if you have a
Cryptographic IOP, it should be used to help speed the encryption
process when writing to tape.

At least this is my outlook on how tape encryption should work.  Oh yea,
make sure you backup DCM un-encrypted.  Do not bother to encrypt IBM
libraries and folders.  Perhaps a library / folder setting of whither to
encrypt or not during a backup.  Heck I only want to encrypt data and
source files, the rest can be left unencrypted.

Dreaming on...

It does not exist, although several customers are clamoring for this
function.

There are a number of technical issues.  Do you encrypt by serial
number,
which means that you can only restore to the same serial number.

What about when you migrate to another platform?  Do you then encrypt
with
2 serial numbers?

What about a D/R situation?

Also, what would be the CPU implications, or would you use an encryption
IOA?
