Overview

Context

According to the data security law, data recovery tests must be performed periodically for the backup and DR data. By performing a recovery, the backup software restores the backup data to the data source. As the service system is running in most of the time, it is not a good practice to perform recovery tests in the production environment. To verify the availability of the backup data, the integrity and reliability of the backup solution, and the system capability to deal with emergencies, you can create new backup resources to verify your backup solution and data recoverability.

Drill Principles

• You are advised to periodically perform recovery drills. For details about how to determine the drill frequency, see the best practice of Creating Backup Policies Based on Service Tiering.
• You do not need to perform recovery using each backup. Make sure that at least one backup of each type of resource has been used for recovery in a certain period.
• To prevent the service system from being affected by drills, create new resources to perform recovery drills.
• After a restoration task is delivered, the recovery is considered successful if the task is successful, the resource can be restored using the backup, and the restored data is correct.
• After a restoration task is delivered, the recovery is considered failed if the task fails or the task is successful but data is lost or cannot be read. In this case, contact the Huawei Cloud engineer to locate and rectify the fault.
• The operator should record the drill cycle, process, and results in detail.
