Backup, which files are backed up       Windows: See the client manual; search
 (Backup criteria)                      on "modified".  In particular, see:
                                         - "Understanding which files are backed
                                           up"
                                         - "Copy mode"
                                         - "Resetarchiveattribute"
                                           (TSM does not use the Windows archive
                                           attribute to determine if a file is a
                                           candidate for incremental backup.
                                         - And, Windows Journal-based backup.
