Local Options ■ Differential backup-Backs up only those files whose archive bits have been set since the last full backup was performed. Because differential backup jobs do not clear a file's archive bit, the files that were backed up in the last differential job are backed up again. It takes longer to process backup jobs using this method. However, this strategy requires only two sets of media to restore a differential backup; the full media set, and the differential media set. In the case of an incremental backup, you require the full media set and every incremental set until the latest set. Note: The above-described backup methods do not apply to the Linux Client Agent. For a description of detailed job scheduling features, see the chapter "Customizing Your Jobs" or the online help.
