Creating a Backup Task

Scenarios

Create a data backup so that it can be used to restore SAP HANA if an error occurs, thereby ensuring SAP HANA reliability.

This section uses an SAP HANA system with SAP HANA Studio installed on a Windows ECS as an example to describe how to completely back up SAP HANA data.

For details about operation requirements and notes, see SAP HANA Database Backup and Recovery released by SAP.

Procedure

  1. On the SAP HANA Studio web page, right-click the SAP HANA system to be backed up and choose Backup and Recovery > Back Up System from the shortcut menu.

    Figure 1 Backup entry

  2. On the Specify Backup Settings page, configure backup parameters.

    The parameters are as follows:

    • Backup Type: specifies the type of the backup. In this section, select Complete Data Backup, indicating that the backup contains all data required for restoring SAP HANA.
    • Destination Type: specifies the target backup type. In this section, select File, indicating that the backup data is stored in a file.
    • Backup Destination: specifies the target backup path. The default backup path, /hana/backup, is the path you have specified.

      For file backup, ensure that the target backup path has sufficient space to store the backup file. You can change the target backup path as needed.

    • Backup Prefix: specifies the backup file prefix. Time or date is recommended, for example, COMPLETE_DATA_BACKUP_20170622.
      Figure 2 Specify Backup Settings page

  3. Click Next.

    Brief information about the backup configuration is displayed.

  4. Confirm the information and click Finish.

    The system starts the backup.

  5. After the backup is complete, click Close.
  6. Log in to the SAP HANA node as user root, switch to /hana/backup, and run the following command:

    ls -l | grep COM

    In the preceding command, COM indicates that the files with prefix COM are to be displayed.

    Displayed backup files are as follows:
