We are currently running Enterprise Vault against an Exchange 2010 DAG. We have two journal archive tasks that point to two separate journal mailboxes. The journal mailboxes are 95% of the time on a database that is active on our second mailbox server. In the case of a database failover to the primary mailbox server, the archiving tasks will not work since they are configured for the secondary mailbox server. What is the best approach for journal archive tasks and multiple DAG members, so that in the event of a database failover you can continue to archive the journal mailboxes? Can I have two additional journal archive tasks configured against the the primary server with the target as the same journal mailbox/archive, and just leave the task disabled until there is a failover?
