4. Journal-based backup
Journal-based backup involves the creation of a local change journal, which TSM then uses to track files that need to be backed up. It therefore uses fewer resources than the usual backup methods, since TSM does not have to compare a list of files on the client with the TSM server; occasional incremental backups are recommended, however, in order to ensure that your journal is up-to-date. Journal-based backup is available for Windows and, on Linux, for Red Hat 5, 6 and SUSE 10, 11. If you wish to use this method of backup, please see the section on the IBM manual for the TSM 6.4 client entitled Configure your system for journal-based backup.
