CCR configurations
Application Agent supports backup in a CCR configuration. CCR is a high availability function of
Exchange Server 2007, and includes the following features:
• Ability to ship logs (transaction log replication) between active and standby server volumes.
• When VSS backup is used with SCC, backups can be performed only at the active server. However,
when VSS backup is used with CCR, backups can also be performed at the standby server.
• Ability to reduce processing loads on the active server by performing backups on the standby
server.
In this manual, the function that performs seed processing automatically when restoring data is called
the automatic seed function. For details about seed processing, see the Exchange Server 2007 manual.
CCR can be configured for performing backups in any of the following four ways:
• Only at the active server
• Only at the standby server
• Using different backup servers for the active and standby servers
• Using the same backup server for the active and standby servers
Performing backup only at the active server
The following figure shows an example of a CCR configuration in which backups are performed only
at the active server.
