5Protecting SAP HANA with EMC NetWorker
White Paper
Executive summary
When adding SAP HANA to the data center portfolio, a key concern is the need fornew procedures and tools for its effective implementation. This concern is justified,as experienced IT professionals know that dispersion of technology stacks, tools, andprocesses can entail a greater risk of IT failure, more difficulty when implementing
change, and higher operational cost and complexity.
In many organizations, IT processes are organized so that a central tool is used toprotect and recover data within the data center, along with consistent processes tomanage backup and restore. These tools and processes are usually operated by ateam implementing a company-wide data protection strategy based on the keyservice-level objectivesRecovery Time Objective (RTO) and Recovery Point Objective(RPO).
With earlier versions of SAP HANA, organizations usually had to add yet more tools,processes, and skillsets to back up and restore SAP HANA, since the built-in optionswere quite limited.
With SAP HANA SPS05 came the HANA BACKINT interface, which enables integrationwith third-party backup tools. This allowed EMC to develop that integration into EMCNetWorker, enabling customers to keep their data center practices consistent byusing a single tool to protect SAP HANA and other data center applications, acrossboth physical and virtualized environments.
EMC NetWorker Module for SAP (NMSAP) is an add-on module for the NetWorkerserver and client that provides backup and recovery services for SAP HANA. Databaseadministrators can continue to use existing, familiar workflows to protect virtual SAPHANA with NMSAP. The solution described in this paper covers NMSAP configuration,and automatic backup and test validation including virtual SAP HANA migration,
backups, and recovery.
This solution shows that the NMSAP delivers:
Easy migration of SAP HANA from a physical to a virtualized environment
Compatibility between the NMSAP backup solution and the virtual HANAdatabase
Easy scheduling of routine backups by the NetWorker console

Introduction
This White Paper demonstrates the functionality of EMC NetWorker for backup andrestore of SAP HANA applications on both physical and virtualized environments,using SAP HANA Studio or SAP NetWeaver DBA Cockpit, and NetWorkers GUI. Thepaper aims to show that EMC NetWorker Module for SAP (NMSAP) can enable
organizations to consolidate scheduling, management, and reporting of backup andrecovery across the data center, using a single tool that also backs up SAP HANAdatabases.
This document provides test validation of migration, backup, and recovery of virtualSAP HANA with NMSAP and serves the following purposes:
Introducing the key solution technologies
Describing the key business benefits of using NMSAP with virtual SAP HANA
Describing how to configure NMSAP for virtual SAP HANA migration andbackup
Describing how to recover virtual SAP HANA with NMSAP
SAP does not currently support incremental or differential data backups. For moreinformation on SAP HANA backup and recovery, refer to the SAP HANA AdministrationGuideand SAP Note 1642148.
To refresh or repurpose a SAP application running on HANA (with SID changed), SAP
does not currently support backint.
This document is intended for data center architects who define backup and recoverystandards for the data center (including SAP HANA systems), as well as for SAP
system administrators who wish to integrate SAP HANA with EMC NetWorker. Thisdocument may also be useful to architects and administrators responsible forimplementing backup and recovery strategies for SAP HANA across physical andvirtualized environments.

backup and restore interfaces, the NetWorker server, and the NetWorker ManagementConsole (NMC).
A SAP HANA database holds most of the data in memory but also uses persistentstorage on disk. During normal database operations, the data is automatically savedfrom memory to the disk at regular intervals. All data changes are also captured in theredo log on disk, which is updated after each committed database transaction. Thedata on disk must be backed up to ensure protection against disk failure. NMSAP is
integrated with the SAP HANA BACKINT interface program, hdbbackint, to provide thebackup, deletion, inquiry, and recovery services for SAP HANA database data andredo logs. Based on the features that SAP HANA supports, NMSAP supports thefollowing SAP HANA data operations:
Manual and scheduled backups
Online backups
Full database backups
Redo log backups
Recovery of a database to its most recent state, a specific point in time, aspecific data backup, or a log position
Recovery to the original host or an alternate host
Deduplication backups and restores with a Data Domain system
Client Direct backups to an advanced file-type device (AFTD)
Configuration with the Backup Configuration Wizard
NMSAP works with the following SAP HANA interfaces on the database server toperform backup and restore operations:
SAP HANA command line interface (CLI) with the hdbsqlcommand SAP HANA Studio GUI
SAP DBA Cockpit in the Computing Center Management System (CCMS) GUI
SAP HANA is an in-memory database that combines transactional data processing,analytical data processing, and application logic processing in memory. This designenables real-time online application processing (OLAP) analysis on an onlinetransaction processing (OLTP) data structure.
SAP HANA can be delivered as an appliance with factory-installed hardware,operating system, and SAP HANA database software. This configuration can be based
on either a single node or a multi-node cluster, using certified hardware provided bySAPs hardware partners. It can also be delivered under SAPs Enterprise SharedStorage and Tailored Data center Integration program, which allows customers to usetheir existing infrastructure.

As shown inFigure 2,the SAP HANA architecture can be deployed in two basicconfigurations:
Single-host (scale-up)
Multi-node cluster (scale-out)
Figure 2.
SAP HANA system architecture
Single-host configuration (scale-up)
In an SAP HANA single-host configuration, all SAP HANA components run on a singleserver. The persistence layer resides on server internal flash and SAS disks. Thescalability of the database is limited by the amount of RAM that can be installed inthe server. A single-host configuration does not provide High Availability (HA)functionality.
Multi-node cluster configuration (scale-out)
In a multi-node cluster configuration, the SAP HANA database is distributed acrossmultiple servers. The scalability of the database is achieved by adding servers to thecluster. Shared storage is required for a multi-node cluster configuration to provideHA functionality. Each node uses its own persistent devices on the shared storagelayer. In case of a node failure, the SAP HANA HA feature reassigns the storage
persistence to a standby node, which recreates the in-memory database part from thestorage persistence.
In a distributed scale-out environment, one node (usually the first one installed) isthe master node. It handles the workload of the NetWeaver stack, the statistics andthe tables located in the row store. For a HANA scale-out database, it is a requirementto have at least three nodes. In a two-node landscape, the table distribution and thedegree of parallel processing do not usually provide worthwhile benefits over asingle-node configuration.

The SAP HANA in-memory database holds the bulk of its data in memory for maximumperformance but still uses persistent storage to provide for startup and recovery incase of a failure. The SAP HANA persistence uses two volumes, Data and Log, asshown inFigure 3.
Figure 3.
The SAP HANA persistence layer
Data and log information are automatically saved to disk at regular savepoints asshown inFigure 4 and described in the following sections.
Figure 4.
Persistence mechanism
Data Volume
Data in memory is asynchronously written to the persistence mechanism as asavepoint every five minutes by default. This data volume capture method uses alocking mechanism to prevent modification of pages while copying modified pagesand capturing open transactions before finally increasing the savepoint version andreleasing the lock.

Log Volume
The log file system captures all database transactions since the last savepoint. It issaved to disk continuously and synchronously after each database transactioncommit at the end of the disk write operation, or if the internal log buffer (1 MB) isfull. This information allows the database to be rolled back to any point in time, aswell as to back out of, or redo, individual transactions. In case of failure, the logvolume allows the database to be restored from the last savepoint onwards.
SAP HANA now runs in production on vSphere, the foundation of the VMware vCloudSuite. You can combine the power of the SAP HANA in-memory platform with vSphereto achieve faster time-to-value, better service levels and lower TCO for yourproduction environments, and take the next step to the software-defined data center.
As shown inFigure 5,the benefits include:
Faster Time-to-ValueAccelerate and automate provisioning and reducedeployment time to hours rather than days. Use template provisioning toensure consistency and scalability across environments.
Better Service LevelsWith vSphere vMotion, live-migrate SAP HANA acrosshosts in minutes with zero downtime and zero data loss. Ensure 99.9% highavailability and maximize uptime by automatically restarting SAP HANA virtualmachines with vSphere High Availability. Automatically manage peak analyticworkloads.
Lower TCOReduce capital expenditure (CapEx) by 70% and operationalexpenditure (OpEx) by 56% through greater utilization of existing resourcesand infrastructure. Unify and manage SAP HANA with the rest of yourvirtualized data center. Improve resource utilization through simplifiedoperations management.

Testing and validation
This section provides the detailed information on test scenarios and results. Weperformed the testing of a single-node HANA backup and restore on a virtualizedenvironment. The test scenarios included:
NMSAP for HANA configuration
Migration from a physical to a virtualized environment using NMSAP
On-demand virtual HANA backup and recovery with NMSAP
Automated backup through the NetWorker console and SAP GUI
NMSAP is an add-on module for the NetWorker server and client software. In thissolution, we use the followings steps to configure the NMSAP for SAP HANA afterinstalling the NetWorker client and NMSAP software on the SAP HANA node.
1. Create a SAP HANA user key and set the credential parameters. The SAP HANAuser key takes the higher precedence because it is more secure than thestandard username/password combination, as a password can be leakedthrough the process list.
Create a user key BACKUP with the hdbuserstorecommand, as shown inFigure 6.This key is then used in step 3.
Figure 6.

4. Create a new group for the new client in the wizard.
5.
On the HANA node, manually create the /usr/sap//SYS/global/hdb/optsubdirectory if it does not already exist.
6. Copy the /usr/sbin/hdbbackint file to that directory or create a symbolic linkthat points from /usr/sap//SYS/global/hdb/opt/hdbbackint to theexecutable file.
7. Modify the parameter settings of the /etc/init_hana_nmsap.utl file, which isthe NMSAP for SAP HANA template configuration file. In this solution, we setthe parameters as shown inTable 3.
Table 3.
Parameter settings of NMSAP for SAP HANA configuration file
Parameter Value Comments

Enable the hdbbackintparameter file in SAP HANA Studio. As shown inFigure9,the location of the parameter file /etc/init_hana_nmsap.utl is specified on
the Configurationtab of the HANA Studio Backup console. Select Use thesame parameter file data backup and log backupto use thesameconfiguration file for both data and log backup.
Figure 9.
Specify the location of NMSAP configuration file in HANA Studio
For full SAP environment protection (including applications such as ERP, BI, and soon), we strongly recommend using NetWorker's powerful features to schedule regularVMware image and critical files backup. This can include the instance profile, thetransport domain configuration file, and other critical files under the /sapmnt,/usr/sap/, and /hana/shared file systems. Additional NetWorker clients can becreated for virtual machines for either traditional backup or VMware ConsolidatedBackup (VCB).
For detailed configuration information, refer to the documents EMC NetWorkerModule for SAP Administration Guideand EMC NetWorker Administration Guide
Release 8.2.
This test scenario validates that NMSAP can be used for migrating SAP HANA from aphysical to a virtual platform with a different OS patch level. Beyond that particularvalidation, this scenario can also be used to restore the backup to a different host forrepurposefor example, using the restored SAP system as a TEST system with thesame SID but using a different hostname.
In this solution, we restore to a virtual SAP HANA database from the backup of aphysical HANA saved on Data Domain using NMSAP. The OS patch of the virtual SAPHANA database upgrades from SUSE Linux 11 SP2 to SP3 by migration.
Before you perform a physical-to-virtual SAP HANA migration, the followingprerequisites must be met:
A virtual SAP HANA database with the same SID, UID (User ID), and GID (GroupID) as the physical HANA has been installed.
Note: Follow the SAP HANA Server Installation and Update Guideand Best Practicesand Recommendations for Scale-up Deployments of SAP HANA on VMware vSpheredocuments to install SAP HANA on vSphere.

Validation results
We verified the table records count and OS version from the recovered virtual HANAdatabase.Figure 13 shows the table records count matching the values recorded onthe physical HANA with the OS patch upgraded. The HANA database is migrated to avirtual machine with a different OS version using NMSAP for HANA and the data isvalidated.
Figure 13.
Validate table records count and OS version on virtual HANA
This test scenario validates that NMSAP integrated with the SAP HANA BACKINTbackup solution is compatible with a virtual HANA database. The testing includes:
Recovering virtual HANA to its most recent state
Recovering virtual HANA to a specific point-in-time
Recovering virtual HANA to its most recent state
Recovery of virtual HANA to its most recent state is required when database data orlog areas become unusable. This can happen if data or log files are damaged by afalse operation, a vSphere data store failure, and so on. In this solution, we validatevirtual HANA recovery to its most recent state with HANA Studio and NMSAP bysimulating data file corruption.

Recovering virtual HANA to a specific point in time
Recovery of virtual HANA to a specific point in time is required when a logical erroroccurs such as accidental deletion of table records or a dropped table. In thissolution, we delete one table to simulate a database logic error. Using HANA Studioand NMSAP, we then recover the virtual HANA to the point in time before the tablewas dropped.
Test procedure
1. Query the current table records count and timestamp, as shown inFigure 17.
