Restoring SAP HANA applications

HYCU for Google Cloud enables you to restore either a whole application or only individual application items to a specific point in time.

Prerequisites

  • The instance to which you are restoring application data is up and running.

  • Only if you plan to restore applications running on instances that use Shared VPC networks. Your user account or the HYCU Managed Service Account (HMSA) must be granted the following permissions in the Shared VPC host project: compute.firewalls.list, compute.networks.list, compute.networks.get, compute.subnetworks.list, compute.subnetworks.use, and compute.subnetworks.get.

  • Only if you are restoring SAP HANA tenant databases without a system database.

    • Tenant databases that you want to restore exist.

    • A system database is online and tenant databases are stopped. For details on how to stop the tenant databases, see SAP HANA documentation.

Limitation

You can restore application data only to an instance that belongs to the currently selected protection set and on which an SAP HANA application has already been discovered.

Considerations

  • When restoring data, the automatic backup of backup catalogs using the Backint agent is disabled until the next backup task.

  • Only if you plan to enable the Clear logs option for the selected restore point. Any subsequent restore using a restore point belonging to the same backup chain will also require the Clear logs option to be enabled.

  • After restoring only a system database, make sure to start all the tenant databases.

Recommendation

After restoring data, it is recommended to perform a full backup of data.

To access the Applications panel, in the navigation pane, click  Applications.

Procedure

  1. In the Applications panel, click the application that you want to restore to open the Details section.

    n Note  The Details section appears only if you click an application. Selecting the check box before the name of the application will not open the Details section.

  2. In the Details section that appears at the bottom of the screen, select the desired restore point, and then click Restore. The Application Restore dialog box opens.

  3. From the Project drop-down menu, select the project that contains the instance to which you want to restore application data. By default, the original project of the instance on which the application is running is selected.

  4. From the Zone drop-down menu, select the zone that contains the instance to which you want to restore application data. By default, the original zone of the instance on which the application is running is selected.
  5. From the Instances drop-down menu, select the instance to which you want to restore application data.

  6. Select the All databases check box if you want to restore the whole application or, from the list of databases that are available for the restore, select the ones that you want to restore.

  7. Specify a point in time to which you want to restore application data. The databases will be restored to the state they were in at the specified time.

  8. Enable the Clear logs switch if you want to initialize the log area. This option is by default disabled if you are restoring application data to the same instance and enabled if you are restoring application data to a different instance.

  9. Click Restore.
