Integration concepts
The Exchange ZDB integration backs up Microsoft Information Store (MIS), Key
Management Service (KMS), and Site Replication Service (SRS), which are replicated
within a disk array.
Data Protector integrates with Exchange Server through:
• The Data Protector ese_bar.exe executable, installed on Exchange Server and
used for retrieving locations of files and folders pertaining to a storage
group/store.
• The omniEx2000.exe command, responsible for mounting and dismounting
databases and purging transaction logs after a transaction logs backup.
An Exchange ZDB specification is created using the omnicreatedl command.
Based on this specification, you can perform a filesystem ZDB using the Data Protector
GUI. During backup, ese_bar.exe resolves database objects and retrieves a list
of files and folders to be backed up. The following happens:
