Using Backup Software to Back Up Local Data to OBS

Application Scenarios

In traditional backup and restore solutions, data needs to be first written to storage devices (like tapes) and then transported to a data center. In this process, data security and integrity are subject to many factors, such as hardware performance and personnel. In addition, data center deployment and maintenance result in complex management and high costs.

Cloud storage is easy-to-use, secure, efficient, and cost-effective, making it an attractive substitute for traditional storage devices such as tapes. OBS is such a cloud storage service that is scalable and stores a massive amount of data. The service and storage nodes of OBS are deployed in distributed clusters, greatly improving its scalability. Data redundancy and consistency check make data stored on OBS secure and reliable. With OBS, you pay for what you use so that costs are easy to estimate.

Third-party backup software, such as Commvault and AnyBackup Cloud, can be connected to OBS for data backup. With such backup software, you can customize backup policies for secure and efficient backups.

Using Commvault to Back Up Local Data in SAP HANA

SAP HANA is a high-performance real-time data computing platform based on in-memory computing. It is commonly used in enterprises that have large amounts of real-time business data to process. Commvault is seamlessly integrated with SAP HANA and OBS to support backups for online databases and logs. If your SAP HANA system becomes faulty or data 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

In the following example, Commvault is used to back up the SAP HANA locally deployed on a single node. 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	Stores backup data in OBS buckets.

A CommCell is a backup management domain and a logical grouping of all software components that obtain, move, and manage data and information.

Backup Process

Install and pre-configure the backup software.
Install and configure the backup server (CommServe), backup media (MediaAgent), and SAP HANA backup client agent (iDataAgent).
Create backup storage space (an OBS bucket).
1. Log in to OBS Console and create a bucket for storing backup data. 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.
Create a Commvault backup policy.
Create a backup policy on CommCell Console and specify the backup period, time, and encryption method.
Check the backup execution status.
During the execution of a backup policy, view the backup execution status on CommCell Console.
(Optional) Restore data.
Restore data to the SAP HANA source host.
