With HBR, you can integrate your SAP HANA database on Alibaba Cloud with cloud native backup systems for unified backup and management.
On November 15th, 2018, Alibaba Cloud's Hybrid Backup Recovery (HBR) service received an official SAP certification, making Alibaba Cloud one of the earliest cloud vendors to receive this certification, right after Google Cloud Platform (GCP). This means that if you deploy an application system supported by the SAP HANA database on Alibaba Cloud, you can integrate the SAP HANA database with cloud native backup systems for unified backup and management. You can also receive SAP official technical support.
Hybrid Backup Recovery (HBR) is a cost-effective, secure and reliable, and easy-to-expand cloud-based data backup service. The HBR client's built-in deduplication and compression functions can significantly reduce the amount of backup data transferred to the cloud, as well as the bandwidth and cloud storage cost.
HBR supports a very high data compression ratio by using Data Deduplication—a powerful technology independently developed by Alibaba Cloud. It reduces the required data storage through identifying and compressing redundant data. In the big data era, we have a lot of duplicate data. The use of the data deduplication technology can reduce the required physical storage space to meet the daily increasing data storage needs. The data deduplication technology provides a lot of practical benefits. For example, it reduces the required storage capacity and cost, as well as the network bandwidth.
It is a typical file-block-based duplicate data removal technology that divides files into multiple chunks. The simplest and most commonly used approach is to hash the value of the hash block, and then use the hash value to search for hash blocks with the same hash value. A Recipe file contains information about the relevant blocks that make up the file. With this Recipe, you can restore the complete file.
In addition, HBR makes full use of the multi-replica function of Alibaba Cloud's native cloud storage service to ensure the security and reliability of SAP customers' backup data on the cloud. This also enables easy backup management and remote disaster recovery of the backup data. Based on Alibaba Cloud's huge storage capacity, HBR provides users with backup and archiving services for data that need to be saved long-term. The backup space is ready-to-use and easy to expand. After integrating HBR (the backup device) with the SAP HANA database by using Backint for SAP HANA, SAP users can seamlessly use Hana Cockpit, Hana Studio, and DB13 on the HBR cloud console. SAP users can also easily back up and recover data from the HBR cloud console. In addition, HBR allows SAP users to back up data from offline physical machines and virtual machines, and Alibaba Cloud virtual machines. In the future, HBR will provide SAP users with more SAP product and scenario support.
Backup devices have been evolving with the SAP system since the day SAP was born—from primitive punch cards to drum memory, magnetic tape, virtual tape library, and today's cloud backup. Cloud backup is currently the peak of backup technologies. In comparison with traditional backup devices, it has the following advantages:
HBR uses Alibaba Cloud Object Storage Service (OSS) to store the backup data. OSS is designed with the cross-zone triplicate storage architecture, and supports data flow convergence validation. The integrated compression code and encryption code can ensure efficient, secure and consistent data storage, complying with the commercial SLA.
By using the high-compression-ratio data deduplication technology, HBR only requires between 1/30 to 1/4 the storage space of conventional backup devices.
HBR's user interface is designed based on human-machine Interaction engineering, and allows users to complete backup scheduling within one minute. The display of query results is also very intuitive and clear.
This document introduces how to configure SAP HANA cluster with SUSE HAE (High Availability Extension) on Alibaba Cloud.
SAP HANA is robust and has its own S/W failover feature, but if a hardware failure occurs on the infrastructure such as an H/W fault or N/W error, the data needs to be protected by an OS level HA mechanism. This document introduces how to configure SAP HANA cluster with SUSE HAE (High Availability Extension) on Alibaba Cloud.
Alibaba Cloud Enterprise-level Elastic Compute Service (ECS) instances are certified for SAP HANA. Most customers expect to configure their SAP HANA system as clustered. It works like below.
1) The two instances communicate each other via a 'Shared Block Storage'
2) SAP request goes through HAVIP
3) The request will be processed on DB1 node
4) In abnormal status of DB1 node
The instance type used in this example is 'Memory Enhanced', which is certified on SAP HANA.
The OS is SUSE Linux Enterprise Service Pack 2. There is no public image, so a custom image is needed.
Alternatively, you can use the Marketplace image on domestic account and international account. At the time of writing, if you are using international account, the region is limited to EU Frankfurt.
In this tutorial, we'll deploy an SAP HANA high availability cross-zone solution on Alibaba Cloud with SUSE Linux Enterprise Server for SAP Applications.
SUSE Linux Enterprise Server for SAP Applications is optimized in various ways for SAP* applications. This document explains how to deploy an SAP HANA High Availability solution cross different Zones on Alibaba Cloud. It is based on SUSE Linux Enterprise Server for SAP Applications 12 SP2. The concept however can also be used with SUSE Linux Enterprise Server for SAP Applications 12 SP3 or newer.
SAP HANA provides a feature called System Replication which is available in every SAP HANA installation. It offers an inherent disaster recovery support.
For details, refer to the SAP Help Portal, HANA system replication:
The SUSE High Availability Extension is a high availability solution based on Corosync and Pacemaker. With SUSE Linux Enterprise Server for SAP Applications, SUSE provides SAP specific Resource Agents (SAPHana, SAPHanaTopology etc.) used by Pacemaker. This helps you to build your SAP HANA HA solution up more effectively.
For details, refer to the latest version of the document SAP HANA SR Performance Optimized Scenario at the SUSE documentation web page:
This document guides you on how to deploy an SAP HANA High Availability (HA) solution cross different Zones. The following list contains a brief architecture overview:
Simple Application Server is a new generation computing service for stand-alone application scenarios. It provides one-click application deployment and supports all-in-one services such as domain name resolution, website publishing, security, O&M, and application management.

This guide provides an overview of how SAP Business One works on the Alibaba cloud platform, and provides details that you can use when planning the implementation of a new SAP Business One system.
Alibaba Cloud and SAP have worked together to test and certify the SAP Business One solution on the Alibaba cloud. SAP Business One, version for SAP HANA has been certified on the Alibaba cloud platform. For more information about how to deploy SAP Business One on Alibaba Cloud, see the SAP Business One deployment guide.
SAP Business One is business management software designed for small and medium-sized enterprises. It was designed with the idea that smaller companies need ERP software to help manage their business, but not the kind of ERP that large and complex organizations need. It has functional modules for finance, customer relationship management (CRM), warehousing and production management, purchasing and procurement, and reporting and analytics.
SAP HANA is an in-memory, column-oriented, relational database management system developed and marketed by SAP. Its primary function as database server is to store and retrieve data as requested by the applications. In addition, it performs high-performance analytics and real-time data processing to address customer’s rapid growing business analysis needs.
This part provides information about how to manage the running state of your ECS instance.
ECS Instance Automatic Recovery is a feature of Alibaba Cloud. It is designed to increase instance availability. If an ECS instance becomes impaired or terminated due to its underlying hardware problem or failure, an identical instance with the same instance ID, private IP address, Elastic IP address and all instance metadata, will be recovered on a different piece of hardware. Users will receive an email during the recovery procedure. Please check more details from here.
