How to License the Agent

The Arcserve Backup Agent for Microsoft Exchange Server uses a count-based licensing method. You must register a number of licenses equal to the number of active Exchange Servers you wish to protect. You may install the Agent on either the active or replica server. Apply licenses on the Arcserve Backup Primary or Standalone Servers.

Examples: How to License the Agent

The following list describes typical installation scenarios:

• Your environment consists of one Exchange Server. You must register one Agent for Microsoft Exchange license and install the agent on the active server. (There is no replica in this example.)
• You wish to back up your Exchange Server 2010/2013/2016 system from a replica. You've set up a Database Availability Group (DAG) to replicate one active server to a passive node. You must purchase one Agent for Microsoft Exchange license (number of licenses equals number of active servers). You can install the agent on the passive node and back up your database from that node. Or, you can install the Agent on the active node.
• You have five active Exchange Server systems that you replicate to multiple passive servers. You must purchase five licenses (number of licenses equals number of active servers). You can install the Agent on all five active servers or on as many replica servers as you need to replicate your environment.
