Tivoli Storage Manager for UNIX Backup-Archive Clients Installation and User's Guide

Encryptkey

Authorized User

The encryptkey option specifies whether to save the encryption key password locally when performing a backup-archive operation or whether to prompt for the encryption key password. The encryption key password is saved to the TSM.PWD file in encrypted format.

If you set the encryptkey option to save, you are only prompted the first time you perform an operation. Thereafter, Tivoli Storage Manager does not prompt for the password.

Note: The Web client saves the encryption key password in the TSM.PWD file. If you do not save the encryption key password, you are prompted for the initial encryption key password when you begin encryption processing.

Table 30 shows how both Authorized Users and non-Authorized Users can encrypt or decrypt data during a backup or restore operation depending on the value you specify for the passwordaccess option. The TSM.PWD file must exist to perform the following Authorized User and non-Authorized User operations. The Authorized User creates the TSM.PWD file and sets the encryptkey option tosave and the passwordaccess option to generate.
