    1) Yes, as long as your restore works, then a duplication of data encrypted via Brocade BES will be seamless to NetBackup - and so when duplicating to a NetBackup KMS encrypted pool - data will be re-encrypted at the tape drive head.

    2) Yes, but do check the LTO Organization's published literature.

    3) Unable to answer, as you haven't described the configuration.

    Questions:

    Q4) I think the answer to Q3, depends upon how you answer this... Is Brocade BES a form of carrier encryption only - i.e. does encrypt the contents of the FC frame, and then decrypt just before it hits the tape drive?  If so, then your tapes are not already encrypted.

    Q5) Or does Brocade BES actually encrypt the backup data within FC packets, and if so, then how does it distinguish between SCSI command traffic and backup data?
