Hugo, after getting the questin wrong;-) and re-reading a few times in disbelief I found on <http://msdn.microsoft.com/en-us/library/ms175477.aspx&gt; - Each data backup includes part of the transaction log so that the backup can be recovered to the end of that backup.

So, in a full backup, all completed transactions will be added to the full dump. everything else will be added to the transaction log dumps if being performed.
