IBM Tivoli Storage Manager for UNIX and Linux Backup-Archive ...

Related tasks“Creating an include-exclude list (optional)” on page 80This is an optional task but an important one. If you do not create aninclude-exclude list, Tivoli Storage Manager considers all files for backup servicesand uses the default management class for backup and archive services.“Setting the client scheduler process to run as a background task and startautomatically at boot time” on page 214You can configure the Tivoli Storage Manager client scheduler to run as abackground system task which starts automatically when your system is started.This is true for both client acceptor daemon-managed and traditional methods ofrunning the Tivoli Storage Manager client scheduler.Encrypting data during backup or archive operationsFor the strongest possible encryption, use 128-bit Advanced Encryption Standard(AES) data encryption, with the encryptiontype option. The data that you includeis stored in encrypted form, and encryption does not affect the amount of data sentor received.Important: The include.encrypt option is the only way to enable encryption on thebackup-archive client. If no include.encrypt statements are used encryption will notoccur.Use the include and exclude options in dsm.sys to define which files to include orexclude from incremental or selective backup processing. A file is eligible forbackup unless excluded by an exclude option. It is not necessary to use an includeoption to include specific files for backup unless those files are in a directorycontaining other files you want to exclude.To encrypt file data, you must select an encryption key password, which TivoliStorage Manager uses to generate the encryption key for encrypting anddecrypting the file data. Store the encryption key password for later use. You canspecify whether to save the encryption key password in a file named TSM.PWD byusing the encryptkey option.Tivoli Storage Manager client encryption allows you to enter a value of up to 63characters in length. This encryption password needs to be confirmed whenencrypting the file for backup, and also needs to be entered when performingrestores of encrypted files.While restoring the encrypted file, Tivoli Storage Manager will prompt you for thekey password to decrypt the file in the following cases:v If the encryptkey option is set to Prompt.v If the key supplied by the user in the above case does not match.v If the encryptkey option is set to Save and the locally saved key password doesnot match the encrypted file.Chapter 4.
