Running SAP HANA Backup Job

This chapter provides a comprehensive guide on how to perform backups for SAP HANA applications using the Catalogic DPX plugin. The Catalogic DPX plugin is easily installed and configured on the SAP HANA system using a script named dpxhdbinst. This script is available in the /opt/DPX/misc/ directory after the Catalogic DPX Client is installed on the SAP HANA system.

Prerequisites

Before running the installation and configuration script, ensure that you have the following information available from your environment:

  • The hostname or IP of the DPX Master Server.

  • The username of the DPX administrator account (default: dpxadmin).

  • The password of the DPX administrator account (default: dpxadmin).

  • The fully qualified path to the DPX root directory.

  • The logical hostname of the SAP HANA node.

  • The name of the DPX media pool that will be used.

  • The name of the DPX device cluster that will be used as a backup target.

  • The name of the DPX device that will be used as a backup target.

  • The System ID (SID) of the SAP HANA database being installed and configured.

Installing and Configuring the DPX Plugin

To install and configure the DPX plugin, follow these steps:

  1. Using the secure shell protocol (SSH), log in to the SAP HANA node host.

  2. At the command line, navigate to the misc directory, using:

cd /opt/DPX/misc

  1. Run the installation and configuration script to install the DPX plugin, using:

./dpxhdbinst

  1. When prompted, enter the following information:

  • The hostname or IP address of the DPX Master Server.

  • The DPX administrator account username.

  • The DPX administrator account password.

  • The DPX root directory (default: /opt/DPX/).

  1. Enter the System ID (SID) of the SAP HANA database. This will set the HDBbackint directory to /usr/sap/<xxx>/SYS/global/hdb/opt/, where <xxx> represents the SID of the SAP HANA database to be protected.

  2. Proceed with installation of the DPX plugin, press 1. Installation will create a link and change permissions of three files and one directory as indicated on the screen.

  3. To continue with configuration, press 2.

  4. Enter the configuration information. When prompted, enter the following:

    • The logical name of the SAP HANA node.

    • The DPX tape pool to use with the SAP HANA database.

    • The DPX device pool to use with the SAP HANA database.

    • The DPX device to use with the SAP HANA database. During configuration, a template file is edited and copied to /opt/DPX/bin/dpxhdb.utl, a link is created, and the file /usr/sap/<SID>/SYS/global/hdb/custom/config/global.ini is updated, where <SID> is the System ID.

  5. Press 3 to exit the script.
