Title: Don't make a full backup if another one already exist for the same day

I need do make backup twice a day, even on "full backup" day.
However, it make no sense to make two full backups on the same day. So this patch limit full backup to one per day.
I can't see in which case it might be necessary to do two full backup on the same day, so I haven't added an option to bypass this feature.
