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