Microsoft Exchange Server 2013 has a very different server role architecture than its previous versions. Exchange 2007 and 2010 had 5 server roles: the Mailbox Server role, Client Access role, Hub Transport role, Edge Transport role, and the Unified Messaging role. That is a lot of roles to need to backup. However, Exchange 2013 has greatly reduced the number of server roles down to two: the Mailbox Server Role and the Client Access Server role. All of the other roles, except the edge transport role which is run on a standalone , have been combined within those two roles. When it comes to backing up and restoring Exchange 2013 this makes Exchange Monitoring much easier for administrators.
