This topic describes how to use Hybrid Backup Recovery (HBR) to back up data from on-premises SAP HANA.

Notice Before the backup, you must disable the backup policy of SAP HANA.

Prerequisites

You have completed the preparations.

Step 1: Create a file named workflow.env

  1. Go to the installation directory of the HBR backup client and create a file named workflow.env in the client subdirectory.
    Note The workflow.env file must be stored in the same directory as the hybridebackup and ids executable files.
  2. In the workflow.env file, enter the username and password of a backup source in the following format: 
        USERNAME=root
    PASSWORD=****

Step 2: Configure backup scripts

Pre-backup script
  1. Download the pre-backup script for SAP HANA.
  2. Configure and save the pre-backup script. The following section describes the parameters that need to be configured in the pre-backup script for SAP HANA. You can configure these parameters as required.
    Parameter Description
    HDB_SQL=/usr/sap/<SID>/HDB01/exe/hdbsql The path of the SQL client for SAP HANA.
    INSTANCE_ID The ID of the database.
    HANA_HOST The host name of the master node.


Post-backup script

Download the post-backup script for SAP HANA and change the path in the script to the local backup path of SAP HANA. Save the script.

Step 3: Create a backup workflow

  1. Log on to the HBR backup client and click Create Backup Workflow in the upper-right corner.
  2. On the Backup Jobs/Create Backup Workflow page, click Pre-backup Script.

  3. In the Script Path field of the Pre-backup Script dialog box, enter the file path of the pre-backup script configured in Step 2.
    Note The script path must be a maximum of 250 characters in length.
  4. Click Preview to check the details of the pre-backup script and click OK.
  5. On the Backup Jobs/Create Backup Workflow page, click Running Plan.
  6. In the Running Plan dialog box, configure the following settings and click OK.
    • If you have a regular backup plan, click Scheduled. In the Backup Policy drop-down list, select a backup policy.
    • If you have no regular backup plan, click Instant.
  7. On the Backup Jobs/Create Backup Workflow page, click Backup Source.
  8. In the Backup Source dialog box, configure the following settings. Then, click OK.
    Parameter Description
    Source
    • Enter the path of a backup source. You can enter a maximum of eight paths, which means that you can back up data from eight directories at a time.
    • The path is dedicated to storing workflow-based backups. The path must be directed to an empty directory.
    • In the configuration of SAP HANA, set the backup path to this path.
    • You can enter a Universal Naming Convention (UNC) path as a source path.
    • Separate multiple paths with carriage returns.
    Use VSS for backup (Windows only) SAP HANA does not support the Volume Shadow Copy Service (VSS).
  9. (Optional) On the Backup Jobs/Create Backup Workflow page, click Network Flow Control.
    Note You can use throttling to set bandwidth limits for backing up data during peak hours to ensure business continuity. If you do not need to configure throttling, you can skip this step and the next step.
  10. (Optional) In the Network Flow Control dialog box, set a period in Work Hours and a maximum bandwidth in Throttling, and then click Add. Confirm the configuration and click OK.
    Note You can use throttling to set bandwidth limits for backing up data during peak hours to ensure business continuity. If you do not need to configure throttling, you can skip this step.
  11. On the Backup Jobs/Create Backup Workflow page, click Post-backup Script. In the Script Path field of the Post-backup Script dialog box, enter the file path of the post-backup script configured in Step 2. Click OK.
    Note The script path must be a maximum of 250 characters in length.
  12. On the Backup Jobs/Create Backup Workflow page, click Submit to start a backup job.
Note
  • If you need to cancel a backup job, locate the running backup job on the Backup Jobs page and click Cancel next to the backup job.
  • If a backup job fails, you can locate the running job on the Backup Job page and click Retry next to the backup job. You can also click the Download icon next to the number of errors to download and view the error report.
