Creating a DR Task

Prerequisites

You can create a DR task only when the cluster is in the Available or Unbalanced state.

Procedure

1. Log in to the GaussDB(DWS) management console.
2. In the navigation pane on the left, click DR Tasks.
3. On the displayed page, click Create.
4. Select the type and enter the name of the DR task to be created.
   • Type: Cross-AZ DR
   • Name: Enter 4 to 64 case-insensitive characters, starting with a letter. Only letters, digits, hyphens (-), and underscores (_) are allowed.

     

5. Configure the production cluster.
   • Select a created production cluster from the drop-down list.
   • After a production cluster is selected, the system automatically displays its AZ.

     

6. Configure the DR cluster.
   • Select the AZ associated with the region where the DR cluster resides.
     

     The production cluster AZ will be filtered out from the available DR cluster AZs.

   • After you select an AZ for the DR cluster, homogeneous DR clusters will be displayed. If no DR cluster is available, create a cluster with the same configurations as the production cluster.

     

7. Configure advanced parameters. Select Default to keep the default values of the advanced parameters. You can also select Custom to modify the values.
   • The DR synchronization period indicates the interval for synchronizing incremental data from the production cluster to the DR cluster. Set this parameter based on the actual service data volume.

     

     

     The default DR synchronization period is 30 minutes.

8. Click OK.

   The DR status will then change to Creating. Wait until the creation is complete, and the DR status will change to Not Started.
