After an SAP HANA instance is registered, you can view the installation status of the Hybrid Backup Recovery (HBR) client for Elastic Compute Service (ECS) on each node of the SAP HANA instance. You must make sure that an HBR client is installed on each node that you want to back up. After the HBR client is installed, you can upgrade, reinstall, uninstall, or delete the HBR client based on your business requirements. You can upgrade multiple HBR clients at the same time.

Prerequisites

An SAP HANA instance is registered. For more information about the backup methods, see Register an SAP HANA instance.

Background information

  • If the version of an HBR client for ECS is outdated, you can upgrade the client to the latest version.
  • If an HBR client for ECS fails to be activated or upgraded, you must uninstall the client and install it again.
  • If you no longer need the backup data in an HBR client for ECS, you can delete the HBR client.

Manage an HBR client

  1. Log on to the HBR console.
  2. In the left-side navigation pane, choose Backup > SAP HANA Backup.
  3. In the top navigation bar, select the region where the SAP HANA instance that you want to back up resides.
  4. Click the SAP HANA Instances tab.
  5. Find the SAP HANA instance that you want to manage, and choose More > View Details in the Actions column.
  6. On the SAP HANA Instance Details page, click the SAP HANA Nodes tab. On the tab that appears, view the installation status of the HBR client for ECS on each node. If the node status is Activated, an HBR client is installed. You can perform the following operations on an HBR client:
    • Upgrade an HBR client

      To upgrade an HBR client on a node, find the node and click Upgrade in the Client Type column.

      Before you upgrade the HBR client, you must disable the backup feature of SAP HANA. For more information, see SAP Note 2009486.

    • Reinstall an HBR client

      To reinstall an HBR client on a node, choose More > Uninstall Client in the Actions column of the node. After the client is uninstalled, choose More > Reinstall Client in the Actions column of the node.

    • Uninstall an HBR client

      To uninstall an HBR client from a node, choose More > Uninstall Client in the Actions column of the node.

    • Delete an HBR client

      To delete an HBR client from a node and delete the node from the instance, click Delete in the Actions column of the node.

      Notice After you delete an HBR client from an SAP HANA node, the existing backup data is still retained.

      To delete the SAP HANA instance after the HBR client is deleted, perform the following steps:

      1. On the SAP HANA Backup tab, click the SAP HANA Instances tab.
      2. Find the SAP HANA instance that you want to delete, choose More > Delete.
        Notice After you delete an SAP HANA instance, the existing backup data is also deleted and the running backup and restore jobs fail to be completed. Before you delete the SAP HANA instance, make sure that you no longer need the data in the HBR client of the instance and no backup or restore jobs are running for the instance. To delete an SAP HANA instance, you must enter the security identifier (SID) of the instance. The SID is three characters in length and starts with a letter. For more information, see How to find sid user and instance number of HANA db?

Upgrade multiple HBR clients at the same time

  1. Log on to the HBR console.
  2. In the left-side navigation pane, choose Backup > SAP HANA Backup.
  3. In the top navigation bar, select the region where the SAP HANA instance that you want to back up resides.
  4. Click Update HANA Clients.
  5. In the Update HANA Clients panel, select the clients that you want to upgrade and click OK.
  6. In the dialog box that appears, confirm the latest version to which you want to upgrade your HANA clients and the client list. Click OK.
    The Client Status changes to Upgrading. After the upgrade, the HANA clients are in the latest version and the Activated state.
