Incremental and differential methods backup files from the time of the last full backup. The differential process backs up the files that have been modified since the last full backup. When the data needs to be restored, the full backup is laid down first and then the most recent differential backup is put down on top of it. The differential process does not change the archive bit value. The incremental process backs up all the files that have changed since the last full or incremental backup and sets the archive bit to 0. When the data needs to be restored, the full backup data are laid down and then each incremental backup is laid down on top of it in the proper order.
