How the Backup Agent Works

Backing Up Online Databases

Backing up Individual Mailboxes or Folders

The Backup Agent allows you to back up and restore Exchange Server databases
or database components (such as mailboxes) using BrightStor ARCserve Backup.
The Backup Agent acts as a go-between for BrightStor ARCserve Backup and the
Exchange Server; it handles all communication between the two systems and
enables data to be passed back and forth.
The Backup Agent resides on the Exchange Server. When BrightStor ARCserve
Backup starts to back up a database or database component, it sends a request to
the Backup Agent. The Backup Agent retrieves the data from the Exchange
Server (using the Exchange Server Backup/Restore API functions) and sends it
to BrightStor ARCserve Backup, where the full database or components are
backed up to your storage media. Similarly, the Backup Agent transfers database
information when data is restored from storage media.
The Backup Agent takes advantage of the Exchange Server's backup/restore API
functions to back up online databases.
For each online database backed up, the Backup Agent instructs the Exchange
Server to prepare the backup operation. The Backup Agent retrieves the
information from the database and passes it directly to BrightStor ARCserve
Backup, which backs it up to a storage drive. When the backup is complete, the
Backup Agent instructs the Exchange Server to end the backup operation.
The following steps describe the data flow when BrightStor ARCserve Backup
uses the Backup Agent to back up individual Exchange mailboxes or folders:
1. BrightStor ARCserve Backup sends a request to the Backup Agent to back up
a specific database object.
2. The Backup Agent extracts information about the specific object and
packages the information for transfer.
3. The Backup Agent transfers the data package to BrightStor ARCserve
Backup.
4. BrightStor ARCserve Backup writes the data to your storage media. The
backup is complete.
