Integration concepts

Data Protector integrates with Exchange Server through the Data Protector
ese_bar.exe executable, installed on Exchange Server. It controls the activities
between Exchange Server and Data Protector backup and restore processes.
You can perform interactive and scheduled full and incremental database backups.
The last full backup combined with incremental prevents data loss if a disk failure
occurs. Transaction logs are backed up to perform rollforward recovery.
Exchange Server databases are grouped into storage groups. Exchange Server
2000/2003 supports up to 4 storage groups and up to 5 databases per storage
group. Exchange Server 2007 supports up to 50 storage groups and up to 50
databases, where each storage group is limited to a maximum of 5 databases. The
databases within a storage group are backed up sequentially. Storage groups are
backed up in parallel. The maximum number of devices used in a session equals the
number of storage groups you want to back up.
Using the Data Protector User Interface, you define which objects and object versions
to restore. Data Protector then passes the information about objects and backup
versions to the backup API. General Media Agents are started and the data flows
from the media to the target Exchange Server. See Figure 28.
