NetBackup has added vendor specific metadata to the VOL1 header it writes to a tape. The NetBackup written header contains a NetBackup signature and a pool ID. The TS1120 and TS1040 drives examine the VOL1 contents looking for the NetBackup signature and pool ID. When recognized, the drive uses the pool ID and the ILEP mode to determine whether to encrypt the volume and which key labels should be used in the encryption process. Since the ILEP method is also a "Scratch Encryption Policy", the existing volser range policy is renamed to the Barcode Encryption Policy (BEP) because it is based on the volser barcode. This paper addresses the Internal Label Encryption Policy for NetBackup.
