Log files

I am new to Idera and just started using SQL Defrag Manager. I am having problems with the log files on the SQLdefragRepository growing very large. My mdb file is around 6 GB and at one time the log file grew to over 40 GB -- almost filling up my drive. I do a transaction log backup every 3 hours.

I did contact support and they told me it was normal. I am not having any luck with the Automated Policies because of this log file growth.

Any suggestions for me?
