multiple Exchange databases, and back up mailbox databases within a group. If an error occurs in
an active mailbox database copy, you can use the data in a passive mailbox database copy to
continue operation.
Application Agent provides backup and restore functionalities for mailbox database copies in the
event of a logical error occurring due to issues such as incorrect email transmission and viruses. The
restore functionality performs seed processing, which resynchronizes data by copying the passive
mailbox database copy to the restored active mailbox database copy.
The DAG configuration manages only mailbox stores, but by using Application Agent, you can specify
both mailbox stores and public folder stores at the same time for backup or restore processing. This
availability is possible because Application Agent excludes public folder stores from processing related
to the DAG configuration, such as stopping replication or the seed function.
There are four types of DAG configurations that use Application Agent:
• A configuration in which the active mailbox database copy is backed up and restored
• A configuration in which the passive mailbox database copy is backed up and restored
• A configuration in which the active mailbox database copy and the passive mailbox database
copy are backed up and restored by different backup servers
• A configuration in which the active mailbox database copy and the passive mailbox database
copy are backed up and restored by the same backup server
Backing up and restoring active mailbox database copies
The following figure shows an example of a DAG configuration in which an active mailbox database
copy is backed up and restored.
