Prerequisites and Must know Configure or integrate Online Database backup for Microsoft Exchange Server 2007 integration

Microsoft Exchange Server 2007 Database Backup integration/Configuration

Below details are captured as per Data Protector backup tool:

Full database backup: Includes all data (database and all log files) regardless of the changes made after the last backup.
Incremental Backup: Includes log files only. Refers to the previous full or incremental backup, whichever was performed last. After the backup, log files are deleted.

Data Protector integrates with Exchange Server through the Data Protector ese_bar.exe executable, installed on Exchange Server
Exchange Server databases are grouped into storage groups. 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
Backup preview is not supported in exchange backups

Every Exchange Server system to be used with Data Protector must have the MS Exchange Integration component installed
Before performing incremental backups, disable circular logging for all storage groups. If the application is cluster-aware, disable circular logging on all cluster nodes.

Circular logging is a Microsoft Exchange mode, where transaction logs are automatically overwritten when the data they contain is committed to the database.
If enabled, this option reduces disk storage space requirements, but does not allow you to perform incremental backups.

Add the Exchange_home\bin directory to the Windows Path environment variable

Using the Exchange Server integration, you can back up and restore the whole server or particular databases listed below:

If your configuration, backup, or restore failed:

Check that Exchange Server services (Microsoft Exchange System Attendant and Microsoft Exchange Information Store) are running.l
Using Exchange System Manager, check that all stores to be backed up are mounted and all stores to be restored are dismounted.l
Perform a backup of the Exchange Information Store using Windows Backup. If the backup fails, fix Exchange Server problems first, and then perform a backup using Data Protector.l
Ensure that the Cell Manager is correctly set on Exchange Server by checking the following registry entry: HKEY_LOCAL_MACHINE\SOFTWARE\Hewlett-Packard\OpenView\OmniBack II\Site
Its name and value must be CellServer and "Cell Manager hostname", respectively.
Examine system errors reported in the debug.log file on the Exchange Server functioning as a Data Protector client. Additionally, examine the errors reported in the Windows Event log.
Check if the following directories exist on the Data Protector Cell Manager:

Make a test filesystem backup and restore of the problematic client. For information, see the HPE Data Protector Help
Create a backup specification to back up to a null or file device and run the backup. If the backup succeeds, the problem may be related to backup devices. See the HPE Data Protector Troubleshooting Guide for instructions on troubleshooting devices.
Try to restart the Microsoft Exchange Server and start the backup again.
Check that the Exchange_home\bin directory is added to the Windows Path environment variable.
When performing incremental backups, ensure that circular logging is disabled by starting Exchange System Manager and selecting Properties from the storage group you are backing up.
If you cannot mount the storage after a successful restore, check that LOGS storage on the same storage group is also restored.
Define a directory for temporary log files in the
Restore
context. Check if the specified directory exists. If it does not, create it or specify another existing directory.
To restore to another system, make sure Exchange Server is installed on that system and has the same organization and site names as the restored server.
