You can encrypt the data that is sent to the server during a backup or archive operation using standard DES 56-bit encryption. Files are selected for encryption using include.encrypt and exclude.encrypt processing. By default, files are not encrypted unless they are explicitly included using the include.encrypt option. For more information about the exclude.encrypt option, see Exclude Options. For more information about the include.encrypt option, see Include Options.
To encrypt file data, you must select an encryption key password, which Tivoli Storage Manager uses to generate the encryption key for encrypting and decrypting the file data. Store the encryption key password for later use. You can specify whether to save the encryption key password in a file named TSM.PWD by using the encryptkey option. While restoring the encrypted file, Tivoli Storage Manager will prompt you for the key password to decrypt the file in the following cases:
