After another set of tests i see that when I select to delete files within 0 days (not the option to prompt), the fast backup option is Ok.
Ok, this suits me, because I can choose the action in the Differences screen. E.g. if I wish to Skip a file marked for deletion in destination but I don't want to delete just now.
