Norton Save & Restore 2.0 and Norton Ghost 14.0

The Norton web site says both Norton Save & Restore 2.0 and Norton Ghost 14.0 do incremental and differential backups.

 

I defined a File Backup job that runs when I decide to run it (no schedule), writes to a DVD, and does a FULL backup of files I selected.

 

I want to define a File Backup job that runs when I decide to run it (no schedule), writes to a DVD, and does an INCREMENTAL backup of files I selected.

 

Please point me to the documentation that shows me how to do that.

 

Thanks, Derek
