Encryption - VERITAS NetBackup White Paper

Encryption

NetBackup protects critical data from unauthorized access and tampering while in transit as well as when it is resident on
backup media. NetBackup performs the data encryption on the client, transfers the data across the network and stores it on
tape in the encrypted format. On restores, the data is read from media and transferred across the network to the client
before decrypting. The encryption algorithm is fully exportable, available in both 56 bit DES for the United States and for
export to most countries, and a restricted 40 bit DES version for countries with import restrictions, such as France.
