Performing Periodic Recovery Drills Using the Backup Data

Background

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 Backup and DR Policies.
  • 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.

Backup Drill

The backup drill process of the three backup types is as follows:

  1. Find a cloud server that runs a business core system and perform recovery drills on a monthly basis.
  2. Log in to the CBR console.

    1. Log in to the management console.
    2. Click in the upper left corner and select a region.
    3. Click and choose Storage > Cloud Backup and Recovery.

  3. Choose Cloud Server Backups. In the right pane, click the Backups tab.
  4. Obtain the backup list of this cloud server. Specifically, choose Server ID, enter the ID of the cloud server you want to perform the drill, and click Search.

  1. Select a backup and click Create Image to go to the IMS private image creation page. Specify an image name and click OK.

  1. After the image is created, use the image to create a server.

  1. View the data on the newly created server and check that the data is as expected.
  1. Find an SFS Turbo file system that is used by a business core system and perform recovery drills on a monthly basis.
  2. Log in to the CBR console.

    1. Log in to the management console.
    2. Click in the upper left corner and select a region.
    3. Click and choose Storage > Cloud Backup and Recovery.

  3. Choose SFS Turbo Backups. In the right pane, click the Backups tab.
  4. Obtain the backup list of this SFS Turbo file system. Specifically, choose File system ID, enter the ID of the file system you want to perform the drill, and click Search.
  5. Select a backup and click Create New File System to go to the file system creation page.

  1. Configure file system parameters and click Create Now.

  1. View the data on the newly created file system and check that the data is as expected.
  1. Log in to the CBR console.

    1. Log in to the management console.
    2. Click in the upper left corner and select a region.
    3. Click and choose Databases > Relational Database Service.

  2. Choose Backups. In the right pane, locate the backup you want to use for recovery, and click Restore in the Operation column.
  3. Choose to restore to a new DB instance and click OK.

  1. The DB engine and version of the new instance is the same as that of the original instance. The new DB instance has the same as the original DB instance by default and must be at least as large as the original DB instance. For details about other parameters, see Buy a DB Instance.

  1. Click Buy. When the instance status changes from Creating to Available, the restoration is successful.
  2. Log in to the DB instance and check that the database data is as expected.
