That is almost certainly happening because the backup is doing database commits. A few releases ago we went to a lot of trouble to ensure that bulk update committed at the end, because re-creating the transaction log was expensive.

Tomorrow I will look at whether I can detect if a transaction is open, and if so, have the backup code wait until it is committed.
