Step 3: Host Processing

Step 3: Guest Processing

• The third step in the backup process is to configure Application-Aware Settings. This feature provides data consistency for the applications (MS Exchange Server, MS SQL Server, MS SharePoint Server, MS Active Directory).
• During the backup process, the available writers will be checked if they are stable or not. Only if they are in a stable state the backup will proceed. This ensures a consistent database snapshot. A consistent database snapshot will be created by quiescing the applications using Microsoft VSS API.

Enabling Application-Aware process gives you two choices:

• Require successful application processing: Choosing this option lets ImageBackup Client tracks the application consistency and triggers the backup process, only when all the VSS writers are in a stable state. You can stop the backup if any of the application writers say for Eg MS SQL writer is not in a stable state or if the VSS writers were not processed successfully after the snapshot.
• Ignored application processing failures: This option, lets ImageBackup Client triggers the backup job when it is scheduled, despite the success/failure of the application processed. It will not process the Application VSS writers and ignores the writer's status. By default, we do not recommend this option as it may lead to data inconsistency of the applications in the backup.

Truncate the transaction logs

• Enabling this option lets ImageBackup Client truncate the Exchange Server logs before initiating the backup process. It purges and commits log files along with the .edb files. This avoids the disk space consumed by the application transaction logs.

Enabling the Truncate the transaction logs will list two choices to choose from:

• Truncate logs only after a successful backup

Enabling this option lets ImageBackup Client truncate the application logs before initiating the backup process. It purges and commits log files along with the .edb files.

• Truncates logs immediately after the snapshot creation

Enabling this option lets ImageBackup Client truncate the application logs immediately after a snapshot is taken and before initiating the backup process. It purges and commits log files along with the .edb files.
