Step 3: Enable Protection

Updated at: Jun 27, 2019 GMT+08:00

Scenarios

If you want to enable protection for all resources in a specified protection group, you can perform steps provided in this section.

When data is written to the disks of the production site server, SDRS synchronizes the data to the disks of the DR site server in real time. Both the production site and DR site can use Cloud Server Backup Service (CSBS) and Volume Backup Service (VBS) to back up the servers and disks.

Figure 1 Enabling protection

Prerequisites

  • The protection group has replication pairs.
  • The protection group is in the Available or Enabling protection failed state.
  • The replication pairs and protected instances in the protection group are in the Available, Enabling protection failed, or Protecting state.
  • After you create a protected instance and enable protection on servers at the production site, modifications to the Hostname, Name, Security Group, Agency, ECS Group, Tags, and Auto Recovery configurations of servers on the production site will not synchronize to the servers at the DR site. You can manually add the configuration items to the servers at the DR site on the management console.

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. In the pane of the desired protection group, click Enable Protection.
  4. In the displayed dialog box, click Yes.

    Once protection is enabled, data synchronization starts.

    NOTE:

    The synchronization time is in direct proportion to the disk capacity. Larger disk capacity requires longer synchronization time.
