5.2 What data items can be backed up and what backup

types are used?

While creating a backup plan, you can select either the Microsoft Exchange Information Store or the

Microsoft Exchange Mailboxes data type.

Microsoft Exchange Information store

When you select this data type, the software will perform a database backup.

You can select the following items to back up:

 The entire information store.

 Individual databases (for Exchange 2010/2013).

 Individual storage groups (for Exchange 2003/2007).

The dismounted databases are skipped during backup. The backup task gets the "Succeeded with

warning" result, if the task backed up at least one database but skipped others because they were

dismounted. The backup task gets the "Failed" result, if the task was completed but skipped all of the

databases because they were all dismounted.

During database backups, Agent for Exchange automatically performs consistency check of database

files. It verifies the page-level integrity of the databases being backed up and validates the

checksums of all database pages and log files. Databases with a checksum mismatch or file header

damage are skipped during the backup.

Database backup types

Full. A regular full database backup stores the selected storage groups or databases along with

transaction log files and Exchange-related information from Active Directory. After a full backup

is created, transaction log files are truncated (p. 57). A full backup is self-sufficient; that is, you do

not need access to any other backup to recover the data from a full backup. The database

backups are the basis for disaster recovery scenarios when it is necessary to recover lost or

corrupted databases, storage groups, or entire information store. Granular recovery from
