You are asking for "versioned backup" software. Programs like SuperDuper create "clone" backups, not versioned backups. I recommend this e-book, which will help you find the best product for your needs: "Take Control of Mac OS X Backups" http://www.takecontrolbooks.com/backup-macosx ___________________________________________ Randy B.
