How create incremental Full System Backup?

[wsplawn]

It is difficult for me to distinguish what parts of the Back up and restore screen apply just to creating a full backup and and which apply just to creating a file backup.

I know I can create a system Image by clicking in the upper left hand area of the screen (the create a system image link). But it is not clear to me how to create an incremental backup of a system image. Do I just select "Create a system Image" again, and Win 7 is smart enough to do an incremental system image backup automatically, or do I need to create some sort of schedule?

It is difficult to tell if schedules apply only to file backups or if they apply to creating a full system backup too.

File backups are incremental.

So, apparently, are full system Image backups.

It appears to me that the left part of the Backup and restore screen (the one with a blue background) and the right part of the screen ought to be thought of as somewhat (if not completely) independent of each other.

As far as I can tell, the scheduling options in Backup and Restore have little or nothing to do with creating a full system image. It might have been better even if MS had put the two in separate tabs, IMHO.
