How the Client Agent for Windows Excludes Database Application Files from Backups

The Client Agent for Windows can exclude database and log files from backups of database applications, such as Microsoft Exchange and Microsoft SQL Server, when performing backups.

During the backup job, the Client Agent for Windows communicates with the database agent to obtain a list of files that the backup job should exclude from the file system backup. The Client Agent for Windows then excludes files from the file system backup based on the response received from the database agent. If the database agent is offline, the Client Agent assumes all files should be backed up and the file system backup job proceeds accordingly.

Example:

When you select a Microsoft Exchange server directory as the backup source and perform file system backup using the Client Agent for Windows, the following exclusion behavior occurs:

• If the Exchange Information Store is online, the Agent for Microsoft Exchange Server provides a list of the Exchange databases and log files that should be excluded from the backup job.

  As a result, Arcserve Backup skips the excluded files and completes the file system backup.

• If the Exchange Information Store is offline, the Agent for Microsoft Exchange Server provides an empty list of Exchange databases and log files that should be excluded from the backup job.

  As a result, Arcserve Backup does not skip the Exchange server files and includes all files during the file system backup.
