Introduction and Overview

Business Challenge SAP HANA is an in-memory data platform that you can deploy as an on-premise appliance, or in the cloud. SAP HANA is a ground-breaking platform that is best suited to the performance of real-time analytics, and the development and deployment of real-time applications. At the core of this real-time data platform is the SAP HANA database that is fundamentally different than any other database engine in the market today. Many IT organizations perform SAP HANA database backups on a nightly basis to meet their th eir backup and recovery window requirements. Most businesses store these backups for thirty days or more. Unfortunately, this leads to rapid growth in backup storage, which has resulted in the continued contin ued use of legacy tape systems as the default solution for database backups. This reliance on tape for backup storage can limit the number  of backups that a business can perform and negatively impact recovery point objectives (RPOs). Additionally, organizations constantly challenge SAP HANA administrators to improve recovery time objectives (RTOs). The process of recovering SAP HANA databases from a previous backup, then rolling a large number of archive/redo logs forward is time consuming and complex. However, recovering the database in the shortest possible time is essential to business operations.

Introducing EMC Data Domain Boost for SAP EMC Data Domain deduplication storage systems continue to revolutionize disk backup, archiving, and disaster  recovery with high-speed, inline deduplication. EMC first offered DBAs the ability to use RMAN integration with DD Boost to backup and recover Oracle databases. EMC has now taken the next step in DBA empowerment by integrating  SAP HANA BACKINT Interface with Data Domain systems. The result of this integration is the DD Boost for Databases and Applications product. SAP HANA only supports full database backups. When you use Data Domain deduplication systems as the backup device for SAP HANA data, the deduplication process stores only unique data on the backup device and streamlines the backup process. The efficiency of a Data Domain system combined with the benefits of DD Boost, dramatically reduces the amount of data transferred to and stored on the Data Domain system. DBAs and application owners can continue to seamlessly use existing, familiar workflows offered by SAP HANA Studio and Command Line Interface (CLI) scripts. This allows the backup process to store the backup in a format that a centralized backup application can understand and use for operations such as centralized cataloging, cloning, retention, and tape-out. This unique and powerful integration gives DBAs and application owners the ability to control their own backup and recovery procedures and write the data directly to Protection Storage. The results are simplicity, improved performance, lower capital expenditure, and lower operational expenditure for the line of business owners. DD Boost for SAP HANA integrates with the S AP HANA BACKINT interface to backup and recover SAP HANA databases and redo log files. The SAP HANA BACKINT agent enables DD Boost for SAP HANA to directly connect to the HANA database. When a backup starts, the following actions occur: • The SAP HANA database server invokes invokes the backint agent. The backint agent implements implements the BACKINT BACKINT API for  SAP HANA through the hdbbackint process. • The database database server server creates creates named named pipes pipes to send data data to the backint backint agent. agent. • The backint backint agent reads reads the data from from named pipes pipes and transfe transfers rs the backup backup data to the Data Domain Domain systems. SAP fully certifies the integration of DD Boost for SAP HANA with BACKINT. The following figure provides a high level overview of the components in an SAP HANA environment that uses DD Boost for SAP HANA.

vLab Backup Environment Overview This Lab contains a small SAP Hana server and two Data Domain servers. Certain configuration tasks may be required during the course of this exercise in order to access the resources involved. The goals for this lab are to demonstrate the use of the SAP Hana tools to t o perform backups and recoveries. These tools are as follows. • SAP SAP Hana Hana Stud Studio io • Hana Hana HDBSQL HDBSQL comm command and Line Line lang languag uage. e. The ddbda suite is already installed and pre-configured.  You will perform most of the tasks using the Hana Studio.
