I just purchased TI11/8053. I loaded it on an XP system, created a full backup task (to be executed one) and a daily differential task that is replacing the full backup after 14 backups (i.e. every 2 weeks). Everything looks great on the XP system. Now I wanted to do the same on a Vista Business notebook but don't have the option to override the full backup after so many differential backups. All I have here is Create a new full backup archive Create an incremental backup Create a differential backup archive no other options on that screen. Is this something specific to Vista? Both PC's point to the same archive location on a network drive.
