How the Agent Communicates With CA ARCserve Backup

Communication between CA ARCserve Backup and the Agent for Microsoft Exchange Server is accomplished through the following:

• The agent is installed on the Exchange Server and facilitates all communication between CA ARCserve Backup and the Exchange Server database during backup and restore operations. In Exchange Server 2010 systems, the agent is installed on any mailbox server in a Database Availability Group (DAG).

  Note: Installation on all DAG mailbox servers is not required.

  This includes preparing, retrieving, transmitting, interpreting, and processing data packets that are sent back and forth across the network.

• When CA ARCserve Backup starts to back up a database or database component, it sends a request to the agent. The agent retrieves the data from the Exchange Server and sends it to CA ARCserve Backup, where the full database or the components are backed up to your storage media.

  Similarly, the agent transfers database information when data is restored from storage media.
