Installing Protection Agents on Exchange Server 2010 Nodes

To protect an Exchange Server 2010 DAG node, you must install a protection agent on the node. For instructions about installing protection agents, see Installing Protection Agents.

System Center 2012 – Data Protection Manager (DPM) enables you to protect Exchange Server 2010 DAG nodes from different DPM servers. However, one node can be protected by only one DPM server. For example, assume that DAG1 has nodes N1, N2, N3, N4, and N5. One DPM server can protect N1, N2, and N5, and another DPM server can protect nodes N3 and N4.

With DPM, the maximum amount of data that you can protect with a single DPM server is 80 TB. Therefore you can protect DAG’s that have up to 20 nodes with a single server or up to 10,000 mailboxes with a DPM server.

Note
When you install a protection agent on a DAG node, DPM displays the following warning: "You cannot protect cluster data in the selected nodes without installing agents on the other nodes." This is a DPM warning when you are protecting clusters. This does not relate to Exchange Server 2010 and you can ignore this message.
