Besides these components, Acronis Backup & Recovery 10Agents have to be installed on all machines that need data protection.1.3.3.1 Management ServerAcronis Backup & Recovery 10 Management Server is the central server that drives data protectionwithin the enterprise network. The management server provides the administrator with: a single entry point to the Acronis Backup & Recovery 10 infrastructure an easy way to protect data on numerous machines (p. 406) using backup policies (p. 399) andgrouping enterprise-wide monitoring and reporting functionality the ability to create centralized vaults (p. 401) for storing enterprise backup archives (p. 398) the ability to manage storage nodes (p. 408).If there are multiple management servers on the network, they operate independently, managedifferent machines and use different centralized vaults for storing archives.The management server's databasesThe management server uses three Microsoft SQL databases: The configuration database that stores the list of registered machines and other configurationinformation, including backup policies created by the administrator. The synchronization database used for synchronization of the management server withregistered machines and storage nodes. This is a database with rapidly changing operationaldata. The reporting database that stores the centralized log. This database may grow large. Its sizedepends on the logging level you set.The configuration and synchronization databases should reside on the same Microsoft SQL Server(called an operational server) preferably installed on the same machine as the management server.The reporting database can be configured on the same or different SQL server.When installing a management server, you can select for both operational and reporting serverswhat server to use. The following options are available:1. Microsoft SQL Server 2005 Express that comes with the installation package and installs on thesame machine. In this case, an SQL server instance with three databases will be created on themachine.2. Microsoft SQL Server 2008 (any edition) previously installed on any machine.3. Microsoft SQL Server 2005 (any edition) previously installed on any machine.
