Sorry, no screenshots available. I was on my way out the door to work when it happened this morning.
I am running Backup v3.2 here. The plans mentioned correspond to the three backups I use; one for Documents, one for Personal Data & Settings and one for Pictures. Each "plan" (that's what they were called in the dialog box) needed a full backup, with the option to keep or delete the old "plan".
Maybe I was affected because my regularly scheduled backups were for today, I don't know.
