Hi Robert, - You may want to upgrade to DP/Exchange 7.1.1 released last month. It adds some nice enhancements when it comes to DAGs.
- There is a new section in the User's Guide with pictures and details with it comes to DAGs. Read the "Database Availability Group (DAG) backups" section here: http://www-01.ibm.com/support/knowledgecenter/SSTG2D_7.1.1/com.ibm.itsm.mail.exc.doc/c_dpfcm_bup_replica_exc.html?lang=en - I also encourage you to read the section titled, "Database Availability Group backup guidelines": http://www-01.ibm.com/support/knowledgecenter/SSTG2D_7.1.1/com.ibm.itsm.mail.exc.doc/c_dpe_bup_dag.html?lang=en As far as your question about filling up the log... try to schedule your INCREMENTAL backups frequently enough to never let that happen. If it does, you should try to run a backup to clear the space, but it's possible that the Exchange server won't let you do anything until you clear some space first.
