I just focussed on the last three lines and counted the 'begins' and 'commits': 4 begin, 3 commit and only the transaction 4 had been commit after the backup reading process...

12:18 AM - Full backup data reading of QotDDatabase ends

12:19 AM - Transaction 4 on QotDDatabase commits

12:20 AM - Full backup of QotDDatabase ends

Nice and simple logic...

Thanks!
