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: If IBM Storage Scale is used for storage, it must have a minimum of 5G PVC size to perform backup and restore operations.
Note: The Applications page shows only local cluster applications or remote DR applications. Remote Backup & Restore Spoke applications do not show up on the Hub cluster. To view Spoke applications, go to Backup & Restore > Backed up applications > Protect apps view.

Application list

The Applications page lists all your OpenShift® applications with their backup details, such as Name, Used, Capacity, DR status, Backup status, Last backup on, Success rate, and Policies. 
Note: The DR status is available only for disaster recovery setup.

Application list The Applications page lists all your OpenShift applications with their backup details, such as Name, Used, Capacity, Backup status, Last backup on, and Policies. 
Note: In the Applications page, if you continue to see applications that got deleted from OpenShift, check whether associated backups are available. If you no longer need to restore those backups, delete the Application CR instance of that application from the CRD.

Assign backup policy

Select applications with no policy assigned:
  1. Select one or more application(s) and click Assign backup policy. Alternatively, for an application, click Assign backup policy from the ellipsis menu.

    The Assign a backup policy slide out pane gets displayed.

  2. Select one or more backup policies. You can select Run backup now to initiate a backup. 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.
  3. Click Assign .
Select multiple applications having a mix of policies:
  1. Select one or more application(s) and click Assign backup policy. Alternatively, for an application, click Assign backup policy from the ellipsis menu.

    The Assign a backup policy slide out pane gets displayed.

  2. In the Policy provider section, select which service you want to use as a policy provider.
  3. Select one or more backup policies. You can select Run backup now to initiate a backup. 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.
  4. Click Assign .
  5. In the Confirm assignment confirmation page, go through the information about the number of applications that cannot be assigned as they use policies that are provided by another backup service.

Manage disaster recovery

For disaster recovery setup in IBM Storage Fusion HCI System, you can do the following actions:
Disaster recovery
Disaster recovery for applications in Metro-DR or Regional DRsetup:
  1. You can select one or more applications and click Manage 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 Manage disaster recovery.
  2. In the Manage disaster recovery window, select your disaster recovery tile (Metro or Regional based on your setup) and click Save.

    Disaster recovery is enabled for the selected application. After you register your applications, go to Disaster recovery > Replicated applications to view the list of applications that are protected by this disaster recovery.

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-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 do the following steps:
  1. In the Applications page, search for your application.
  2. Search for the application and click the ellipsis overflow menu of of the record and click Manage disaster recovery.
  3. In the Manage disaster recovery window, select No disaster recovery tile.
  4. Click Save.
Alternatively, you can do this action from the Replicated applications page.
