Exchange 2010 - DAG and Circular Logging RRS feed

  • Question

  • We have an Exchange 2010 environment with a DAG setup with 2 hosts.  We're thinking of enabling Circular Logging and was wondering if there's any downside to this?

    From my perspective:

           1) The chances of both servers going down will be slim, so the logs won't be used for DR purposes. 

           2) Circular Logging will free up 400-500 GB of space

           3) If our backups fails and the logs doesn't get truncated, we won't have to worry about it stopping Exchange from functioning

     

    Are there any major downside or pitfalls of enabling circular logging in a DAG?  The only other question is that since the DAG is based around log shipping and replaying, I would assume that there's a mechanism in place to prevent the logs from being overwritten until it's been copied/replayed into the passive copy?
