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

 

Frank
