In this research we have improved the backup and disaster recovery system, for SAP HANA by utilizing the NetApp SnapCenter plug in. This plug in allows us to perform storage based Snapshot backups ensuring consistency through the use of SAP HANA databases application programming interfaces (APIs). The backups are stored in the SAP HANA catalog. Can be easily accessed through the SAP HANA studio or cockpit. Users have the option to choose these backups for data restoration and recovery purposes. Using SnapCenter, which manages NetApp Snap Mirror technology we can duplicate copies from storage to secondary backup storage. Backup retention policies can be customized for both primary and secondary storage locations. The SnapCenter Plug In takes care of managing Snapshot copy based data backups, log backups and the backup catalog for SAP HANA. Additionally it facilitates file based backups to ensure block integrity checks, on the SAP HANA database are performed accurately.
To create a backup, to a location we rely on Snapshot copies that are generated on the storage. This means that we can retrieve the data directly from the storage system without putting any strain on the SAP database server. The primary storage system is immediately connected to the storage. It transfers the backup data to its destination using a NetApp Snap Vault disk to disk backup solution. After the transfer of all data from the source to the destination future backups only replicate the modified blocks to the storage. This significantly reduces both the load, on the storage system and the time required for a backup. This efficient backup process not reduces strain on our storage but also speeds up overall performance by optimizing data transmission and ensuring prompt execution of backups
The illustration above shows an example of a Recovery Time Objective (RTO), for a 1 terabyte (TB) database using Snapshot backups. When using Storage based Snapshot backups the RTO is determined solely by the time it takes for the database to start and recover. This means that regardless of the size of the database the restore process can be completed within seconds. The timing of the restoration and recovery processes also affects the recovery time. However if backups are performed frequently such as every six hours it helps organizations by limiting the forward recovery time to a minimum.
There are two methods, for carrying out disaster recovery for SAP HANA; replicating the database layer using SAP system replication or replicating the storage layer using storage replication technologies. In this research we conducted tests on disaster recovery solutions that utilize both asynchronous storage replication. To ensure data transmission the sites main database is duplicated to the disaster recovery site using Snap Mirror. In storage replication data is replicated immediately to the disaster recovery site ensuring no data loss but potentially causing some latency in the performance of the site. On the hand asynchronous storage replication allows for a delay in data transmission reducing the impact, on the primary sites performance but potentially resulting in minimal data loss during a disaster. By testing both replication methods this study aimed to assess their effectiveness and determine which approach suits an organizations needs and priorities.
The image above shows a setup, with three sites, where the secondary data center is located near the center. This setup allows real time duplication of data ensuring a Recovery Point Objective (RPO) of zero. Additionally the data is asynchronously copied to a distant data center as a precaution against incidents that could disrupt operations in both the primary center and local disaster recovery centers. The minimum achievable Recovery Point Objective (RPO) depends on how data replication occurs, which is limited by the bandwidth between the primary and remote disaster recovery centers.
The implementation and evaluation of SAP HANA, in data centers highlight its impact on data management and processing. This study showcases how SAP HANA excels at analyzing datasets in real time confirming its effectiveness in datacenter settings. The testing method shows improvements in the efficiency and reliability of data processing emphasizing the importance of having a backup and disaster recovery plan in place. Integrating SAP HANA with existing IT systems brings both challenges and opportunities so it's crucial to approach its implementation for a transition. Future research should focus on enhancing the scalability and compatibility of SAP HANA with data sources to develop efficient data management solutions, for corporate environments [13-15].
