        What are the tools available to doing encryption outside of
Netbackup and than taking that encrypted data to tape?? Are these
products expensive??? We may have a requirement at our site for such
thing for few servers.
 
Thanks
Sandeep

        Your other option is to just encrypt the data yourself before it
hits tape - its what we do at my workplace if we need encrypted backups.

                Data written to tape is not normally encrypted.

                There is a NetBackup Encryption Option that you can
purchase on a per client basis that encrypted the data from the client
all the way to the tape. The encryption strength can be set anywhere
form 40 or 6 bit DES up to 256 bit AES (assuming you have NBU 5.1 or
higher).

                Bear in mind that encryption will make the data
essentially uncompressible so turn on software compression on the client
of you want it and use the uncompressed tapes drives. Since encryption
(and compression) will take place on the client, it will impact backup
speed and varies by how high the encryption is set.

                The other option is look for hardware compression
between the Media server and the tape drives.

                Guys,

                    When a backup is written to tape, is there any type
of encrypting that occurs and if not is there something within Netbackup
you can turn on to make the data encrypted. 

                 

                Thanks
