Easily do a full backup?

I like to do a full backup once a week and usually don't want to bother with

incremental backups. Yet when I click on Backup Files in the Backup and

Restore Center, it seems to only do a incremental backup no matter what your

'Settings' are. The only way I see to ever do a full backup is to go

through this whole rigamarole and check 'Create a new, full backup now in

addition to saving settings' and do that each time. What am I missing? I

don't see anyplace to select whether you want a full backup or an

incremental backup.
