Enabling Protection

Scenarios

You can enable protection for a protected instance in a protection group.

After protection is enabled, data synchronization starts for the protected instance.

Prerequisites

The status of the protected instance is Pending protection or Enabling protection failed.

Procedure

1. Log in to the management console.
2. Click Service List and choose Storage > Storage Disaster Recovery Service.

   The Storage Disaster Recovery Service page is displayed.

3. Choose Asynchronous Replication. In the right pane, locate the replica pair housing the protected instance you want to enable protection and click the number in the Protected Instances column.

   The Protection Groups tab page is displayed.

4. In the navigation tree, choose the target protection group.

   The protection group details page is displayed.

5. In the Protected Instances area, locate the target protected instance, choose More > Enable Protection in the Operation column.

   

   If you want to enable protection for multiple protected instances, select the desired instances and click Enable Protection above the instance list.

   

6. In the displayed dialog box, confirm the protected instance information and click Yes to enable protection. The protected instance status changes to Enabling protection.

   

   

7. After protection is enabled, the protected instance status changes to Synchronizing, indicating that differential data is being synchronized.

   

   

   After protection is enabled, differential data is read from disks and synchronized to the disaster recovery site. During this period, the disk read bandwidth increases, and services may be affected, so you are advised to enable protection during off-peak hours.
