Using Commvault to Back Up Local Data in SAP HANA

SAP HANA is a high-performance real-time data computing platform based on the memory computing technology. Enterprises that need to process a large amount of real-time service data may use SAP HANA. The backup software Commvault is seamlessly integrated with SAP HANA and OBS and supports backup for online databases and logs. When a fault occurs in the SAP HANA system or service migration is required, Commvault can help you quickly and easily restore data, thereby providing enterprise-level data protection for SAP HANA.

Commvault V11 is recommended in this scenario.

Logical Architecture

The following uses Commvault as an example to describe how to back up the SAP HANA deployed on a local single-node system. Figure 1 shows the logical architecture.

Figure 1 Logical architecture

Table 1 describes the components in the logical architecture.

Table 1 Component description

Component

Description

iDataAgent (iDA)

Backup client agent, which is deployed on the SAP HANA node to obtain data to be backed up from SAP HANA.

CommServe (CS)

Backup server, which is deployed on the backup management node and is responsible for formulating global backup policies and scheduling backup services.

MediaAgent (MA)

Backup media, which is deployed on the backup service node and stores backup data to OBS.

OBS

In backup scenarios, OBS stores backup data. Buckets are containers on OBS and data is stored in OBS buckets.

A CommCell is a backup management domain and a logical grouping of software components. Such software components obtain, transmit, store, and manage data and information.

Backup Process

  1. Installing and pre-configuring the backup software

    When backing up SAP HANA, you need to install and configure the backup server (CommServer), backup media (MediaAgent), and SAP HANA backup client agent (iDataAgent).

  2. Creating backup storage space (OBS bucket)
    1. Log in to OBS Console and create a bucket as the backup data storage space. For details about how to create a bucket, see Creating a Bucket.
    2. Create a cloud repository on CommCell Console. Enter the OBS endpoint address, access keys, and the bucket name to associate the MediaAgent of Commvault with OBS.

      CommCell Console is a graphical user interface for managing CommCell environments, monitoring and controlling activity jobs, and viewing activity-related events.

  3. Creating a Commvault backup policy

    Create a backup policy on Commcell Console and specify the backup period, time, and encryption mode.

  4. Checking the backup execution status

    During the execution of a backup policy, you can view the backup execution status on Commcell Console.

  5. (Optional) Restoring data

    Restore data to the SAP HANA source host.
