WhenBackup Exec runs a full or incremental backup, the time the backup launches
is recorded in the Backup Exec database. The next time an incremental or
differential backup launches, Backup Exec compares the file system time to the
backup time recorded in the Backup Exec database. If the file system time is later
than the database time, the file is backed up.

Let me try to explain the above. Let's say you run a Full backup on Sat at 11 p.m. BE will record the time in its database.
If you run an Incremental on Mon at 11 p.m., BE will again record this time in its database. It will then compare the modified time of the files with the timestamp from the Full backup and backup those files whose modified time are later than the Full backup timestamp. If you run an Incremental backup on Tues, BE will record the timestamp in its database. It will compare the modified time of the files with the Monday Incremental backup timestamp and backup those files whose modified time are later than the Mon Incremental backup timestamp.
If, however, you are running Differential backups on Mon and Tue, then no further timestamps will be recorded in the BE database. Files whose modified time are later than the Full backup timestamp will be backed up on both days.
I hope my explanation is clear enough. If not, let me know.

Alas, my secret is out. My puny brain cannot fathom your novel scheme of doing a differential backup after an incremental backup. Normally, differential backups are done after a full backup. What are the advantages of your scheme? Do you also do incremental backups after a few differential backups?
