Creating a Protected Group

Prerequisites

• At least one production site has been created.
• In the backup scenario, a Kubernetes cluster has been added to the production site, and application resources have been added to the cluster.
• In the DR scenario, a Kubernetes cluster has been added to both the production site and DR site. In addition, application resources have been added or data volumes exist in the production cluster.

Context

Protected objects in a protected group must reside on the same storage device.

Procedure

1. In the menu bar, choose Protection.
2. Click Create.
3. Select a protected object.
   1. Select kubernetes as the protected object type.
   2. Select Production Site and kubernetes Cluster where Kubernetes to be protected resides.
   3. Select kubernetes Object to be protected. You can select Application resource or Data volume.
      1. If you select Application resource as the kubernetes object to be protected, select the application resources to be protected.

         If you need to refresh the application resource information, click Refresh in the Operation column of the corresponding resource.

      2. If you select Data volume as the kubernetes object to be protected, you can select Replication or HyperMetro as the protection type.
         • If you select Replication, you need to select the storage backend where the data volume resides and select one or more data volumes as protected objects as required.
         • If you select HyperMetro, you need to select the HyperMetro domain where the data volume resides. The system automatically selects all data volumes in the HyperMetro domain and cannot deselect them.
   

   • If the protected object is an application resource, only one application resource can be added to one protected group.

   • If protected objects are data volumes and the protection type is Replication, a maximum of 128 data volumes can be added to a protected group when the protected group is created. After a protected group is created, you can add protected data volumes by adding protected objects. A maximum of 128 protected data volumes can be added at a time. If you want to add more than 128 protected data volumes, add them in batches. The number of data volumes supported by a protected group is the number of storage NAS remote replication pairs minus one. For details about how to add a protected object, see Adding/Deleting a Protected Object.
   • If the protected objects are data volumes and the protection type is HyperMetro, the number of data volumes supported by the protected group are the number of pairs of storage active-active file systems minus 1.

4. Click Next.
5. The system automatically matches supported protection policies. Select a proper protection policy and configure a time policy based on your data protection solution. If application consistency is involved, configure an application consistency policy.
   1. If you select application resources as protected objects, perform the following operations to set a protection policy:

      Click Settings. In the Set Protection Policy dialog box, set the protection policy.

      • If the selected data protection solution is Local Storage Backup for Application Resources, set protection policy parameters as described in Table 1.

6. Click OK.
7. Click Next.
8. Set Name and Description of the protected group.
   • Name: contains 4 to 32 characters, including letters, digits, hyphens (-), and underscores (_), but cannot start with a hyphen (-).
   • Description: contains 0 to 255 characters.

9. Click Finish.
10. Click OK.
    

    • If the data protection solution is Cross-Cluster Replication for Application Resources, after a protected group is created, the Kubernetes cluster at the standby end automatically creates an application resource that is the same as that at the active end and cannot be deleted.
    • After a protected group is created, ensure that the primary and secondary ends of the CDR protection plan are in the Normal state before performing other operations except refreshing and deleting the protected group. Click the protected group, click the Abstract tab, and check whether Protection plan at the active site and Protection plan at the standby site under CDR protection plan status are Normal.
