Creating a Replica Pair

Scenarios

You can set up the replication relationship between the production site and disaster recovery site by creating a replica pair.

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 upper right corner of the page, click Create Replica Pair.

    Figure 1 Service Overview

  4. Select the type of the replica pair you want to create and configure parameters by referring to Table 1.

    1. Cross-AZ: The production site and disaster recovery site are located in different AZs of the same region.

    2. Cross-region: The production site and disaster recovery site are located in different regions.
