Protecting your applications

Applications contain resources, such as microservices, databases, and other stateful data distributed across projects. IBM Storage Fusion provides ways to do application-centric backup, which provides data loss protection for your applications.

Note: An application can only be protected by either Backup & Restore or Backup & Restore (Legacy) but not both.

For non-Metro sync DR setup in IBM Storage Fusion HCI System and IBM Storage Fusion, you have the Applications page with a list of all applications.

For Metro sync DR setup in IBM Storage Fusion HCI System, the Applications page has Local and Remote tabs. Here, all the local applications are listed in the Local tab.

Note: If IBM Spectrum Scale is used for storage, it must have a minimum of 5G PVC size to perform backup and restore operations.

Application list

The Applications page lists all your OpenShift® applications with their backup details, such as Name, Used, Capacity, Replication status, Home site, Backup status, Last backup on, Success rate, and Policies. 

Actions you can do in the Applications page:
  1. Use the Search field to filter and find your record from the list. You can use the settings icon to customize the headings. To view the application details, click the Name link of the record or click Details in the ellipsis menu.
  2. Assign a policy from this page. Select one or more applications and click Assign backup policy. Alternatively, you can select an application and click Assign backup policy from the ellipsis menu. The Assign a backup policy slide out pane gets displayed. You can select one or more backup policies and click Assign. If you do not see any policy that suits your requirement, create a new policy. For the procedure to, create a new policy, see Managing backup policies for application workloads.
    Note: You can assign only one policy to an application.
  3. To start the backup of an application right away, click Backup now in the ellipsis menu of the application record.
  4. Restore the application backup. For the steps to, restore an application resource, see Restoring an application.
For Metro sync DR setup in IBM Storage Fusion HCI System, you can do the following actions:
Disaster recovery
Disaster recovery for applications in Metro sync DR setup:
  1. You can select one or more applications and click Disaster recovery to register applications for disaster recovery. It creates Persistent Volumes (PVs) for the selected applications that allow access to mirrored data. Alternatively, you can click the ellipsis menu of an application and click Disaster recovery.
  2. In the Disaster recovery window, click Add. The disaster recovery is added for the selected applications.

A message gets displayed informing you that the disaster recovery got initiated. After successful completion, the Replication status displays Synchronized with a green tick. If the disaster recovery completes with errors, then an error message gets displayed. If the application is affected, then click View configuration in the error message, correct the configuration issue and then retry. For more details about Metro sync DR and its prerequisites, see Metro-DR (Disaster Recovery) and Metro-DR for IBM Storage Fusion HCI System.

Remove disaster recovery
If you no longer need disaster recovery for your application, then select Remove disaster recovery from the ellipsis menu. In the Remove disaster recovery window, click Remove. Alternatively, you can do this action from the application details page.

Remote application list

For Metro sync DR setup in IBM Storage Fusion HCI System, you can select the applications to fail over to the local cluster.
  1. Go to the Remote tab.
  2. Select one or more applications and click Failover. The Failover remote applications window gets displayed. It also indicates the number of applications available for failover.
  3. In the Failover remote applications window, click Failover. It creates the Persistent Volumes (PVs) that belong to the applications in the local site. After relocation is complete to remote cluster, a success message is displayed on the screen. The Replication status changes to Failing over. After the successful completion of failover, the application is removed from the Remote tab list.
  4. To verify, go to the Local tab and search for the application that you did a fail over on the remote side.
