Step 3: Application-Aware Processing

When backing up instances with applications, there is a chance of data corruption while taking a snapshot as the application writers may not be stable. It is necessary that the application writers are in a stable state when the snapshot is taken, otherwise, the backup database will be corrupted, causing inconsistency during recovery.

• By enabling Application-Aware Processing, BDRSuite Backup for AWS ensures the application is prepared for backup by quiescing the application writers before the snapshot is taken so that an application-consistent backup is guaranteed. After the snapshot is taken, the applications resume normal operations in minimal time without affecting application performance.
• In BDRSuite Backup for AWS, to backup EC2 instances with application-aware processing, it is mandatory to install BDRSuite Integration Service (VIS) for AWS in the required target EC2 instances before configuring the backup job.
• To know more about downloading and installing VIS, go to the VIS Management section.
• After installing the VIS in the target instances and adding the instance details in the BDRSuite Backup Server, you can proceed with backup configuration by enabling the Application-Aware checkbox for the required Windows instances selected for backup.
• To apply Application-Aware Processing for all the instances listed for backup, enable the checkbox for the column header Application-Aware.
• In some cases, you may want to skip application-aware processing for certain volumes in the instances selected for backup. To exclude those volumes, enter the names of the volumes in the exclusion text box. You can add multiple volumes for exclusion by clicking on the comma key after each volume.
