Ok a strange thing regarding the log.

1. This backup has been about 30GB for quite sometime and we do full daily log backups and hourly append log backups from a maintenance plan. Is there a setting in the backup that is not committing the transactions in the backup?? What is strange is right after the free space loss is when the backup all of a sudden changed.

Basically it has been a steady growth of space up to the 30GB and held there since around 5/14.
