Exchange Database

The Exchange Database application protects Exchange databases for disaster recovery.

The Exchange Database application backs up the following components:

  • Exchange databases

  • Transaction logs

If a system failure occurs, such as the breakdown of hardware, software, or the operating system, then the Exchange Database application can perform a point-in-time recovery of a database. This capability ensures that a database is always ready for use.

Database Availability Groups (DAG)

Using the Command Center, you can back up and recover Exchange databases only on DAG clients.

With the Exchange Database application, you can create a single DAG client to manage a complex DAG architecture. Through the DAG client, you can set up a single set of policies and operations and administer the DAG client through a single CommCell Console. If your DAG architecture is distributed geographically, then you can back up data at each site to avoid increasing traffic on your wide area network (WAN), but you can restore data from any site.

For Exchange 2013 SP1 and more recent versions, the Commvault software supports DAGs without a cluster administrative access point. This DAG configuration that does not require an IP address, and it does not use a Cluster Name Object (CNO) or network name resource. Also, the cluster information is not recorded in the DNS. For more information, see the Microsoft TechNet article "Managing database availability groups",

Recovering Messages from an Offline Exchange Database

You can recover messages from an offline copy of an Exchange mailbox database.

You can use this recovery method for mailbox databases only.

Granular Recovery of Messages from an Exchange Database Block-Level Backup

You can perform a granular recovery of messages without restoring the entire database.
