pronto 16 Report post Posted September 21, 2016 Hi Community, we changed our single server Exchange setup into a DAG with two servers in an active/passive setup. I read the Exchange agent manual but the only thing I figured out is that we need just a license for each Exchange server to backup, but no further information about backup a DAG was available. So I've a few questions: 1) Is it possible to backup only the passive node in a DAG envirionment? 2) How does Retrospect deal with the transaction logs? 3) Are there some No-goes which are not present in a regular one server setup. Currently we are using Retrospect 10.0.2.119 and Exchange 2010 Standard RU15 Thx & Bye Tom Share this post Link to post Share on other sites
