The serverrestores the base file along with the updates from the changed (delta) subfile sothat what you receive is the latest backed-up version of your file.Related concepts“Adaptive subfile backup processing” on page 370“Determine compression and encryption processing” on page 75Related reference“Exclude options” on page 366“Subfilebackup” on page 483“Subfilecachepath” on page 484“Subfilecachesize” on page 485Control processing with an include-exclude listThere might be files on your system that you do not want to back up. These filesmight be operating system or application files that you can easily recover byreinstalling the program, or any other file that you can easily rebuild.Use the include and exclude options in the client options file (dsm.opt) to definewhich files to include or exclude from incremental or selective backup processing.A file is eligible for backup unless excluded by an exclude option. It is notnecessary to use an include option to include specific files for backup unless thosefiles are in a directory containing other files you want to exclude.The include-exclude list might contain items specified by the server. To view thecontents of your include-exclude list, use the query inclexcl command.Tivoli Storage Manager uses management classes to determine how to manage yourbackups on the server. Every time you back up a file, the file is assigned amanagement class. The management class is either a default chosen for you, or oneyou assign to the file using the include option in the include-exclude list. If youassign a management class, it must contain a backup copy group for the file to bebacked up.You can also add include-exclude statements in the Tivoli Storage Manager ClientGUI directory tree. The preview command allows you to see the resultant effects ofthe currently defined include-exclude list without need of performing an actualbackup of data.Related tasks“Creating an include-exclude list” on page 66“Set the client scheduler process to run as a background task and startautomatically at startup” on page 221Related reference“Preview Backup” on page 578Data encryption 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 include is stored in encrypted form, and encryption does notaffect the amount of data sent or received.110 IBM Tivoli Storage Manager for Windows Backup-Archive Clients: Installation and User's Guide
