You can encrypt the data that is sent to the server during a backup or archive operation using standard DES 56-bit encryption. Use the include.encrypt and exclude.encrypt options to select files for encryption processing. By default, the client does not encrypt files unless you include them for encryption processing using the include.encrypt option. For more information about the include.encrypt option, see Include Options. For more information about the exclude.encrypt option, see Exclude 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. You can save the encryption key password in the TSM.PWD file using the encryptkey option. While restoring the encrypted file, the client prompts you for the key password to decrypt the file in the following cases:
