Enabling Protection

Scenarios

You can enable protection for all resources in a protection group.

After protection is enabled, data synchronization starts for all protected instances that meet the prerequisites in this group.

Prerequisites

• The protection group contains protected instances.
• The status of protected instances in the protection group 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 replica pair list, locate the replica pair you want to operate and click its name to go to the Overview page.

   

4. Click the Protection Groups tab and then select the desired protection group on the left to view the protection group details.
5. In the upper right corner of the basic information area, choose More > Enable Protection.

   

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.
