  2. In the upper-left corner of the console, select the region where the cluster that you want to manage is deployed.
  3. Find the cluster you want to manage and click the cluster ID.
  4. In the left-side navigation pane, choose Settings and Management > Backup and Restore.
  5. Click Backup Policy Settings.
  6. On the Backup Policy Settings page, click Edit. In the dialog box that appears, configure the following parameters.

      Note To prevent data loss, automatic backup must be performed at least twice a week.

    Data Backup Retention Period Specify the retention period for level-1 backups and level-2 backups.
