1.2 HyperBDR's Core Value in This Project
AWS Agentless Migration: Adopting an agentless method to directly read underlying storage, avoiding Agent installation on production SAP hosts, ensuring business stability, and reducing operational complexity.
Boot in Cloud: Using object storage as an intermediate layer to enable one-click cloud startup, significantly reducing target-side storage costs while supporting rapid business recovery, meeting RTO < 5 hours requirement.
Policy-Based Synchronization: Based on RPO < 24 hours requirement, flexibly configuring synchronization strategies, supporting regular backup and manual synchronization, ensuring data consistency.
2. Business Challenges & HyperBDR's Response
SAP core business system cross-cloud disaster recovery scenarios often face the following challenges. This project provides solutions through through HyperBDR:
| Challenge | Description | HyperBDR's Response |
|---|---|---|
| Critical Business Continuity Requirements | SAP system is a core production system, unable to perform production system stop-write, shutdown, or active-standby switch operations during drills, placing extremely high requirements on low-intrusiveness of disaster recovery solution. | HyperBDR adopts an agentless architecture, deploying an independent Agentless conversion node in AWS to directly read underlying storage, achieving business-unaware backup without modifying production environment host configurations, supporting drill zero business interruption. |
| Cross-Cloud Heterogeneous Environment Adaptation | From AWS to Alibaba Cloud, need to ensure SAP system (ABAP + HANA) runs normally in Alibaba Cloud environment, including driver adaptation, network configuration, system parameters, etc. | HyperBDR's automated driver adaptation capability automatically identifies source instance specifications and injects drivers adapted to Alibaba Cloud architecture, ensuring driver compatibility across cloud environments, supporting one-click startup of SAP systems. |
| Data Consistency Assurance | Adopting file-level synchronization (EFS → NAS) and host-level disaster recovery replication two methods, need to ensure data integrity and consistency of both synchronization mechanisms, avoiding data loss or corruption. | HyperBDR adopts object storage as an intermediate medium, combined with policy-based synchronization capabilities, supporting regular backup and manual synchronization, ensuring integrity and consistency of data synchronization, while forming dual-layer data protection with file-level synchronization (EFS → NAS). |
These challenges are common in most SAP core business system disaster recovery scenarios, so the HyperBDR capabilities demonstrated in this project have reusable best practice value.
3. HyperBDR Solution & Architecture
3.1 Overall Approach
This project adopts a dual-layer data synchronization architecture, combining file-level synchronization (EFS → NAS) and host-level disaster recovery replication (HyperBDR object storage), ensuring data integrity and consistency. The HyperBDR console is deployed on the Alibaba Cloud side, responsible for global scheduling, policy configuration, and disaster recovery drill command. The core advantage of this solution is that no Agent needs to be installed on production SAP hosts, significantly reducing deployment and maintenance complexity, while utilizing the low-cost characteristics of object storage to achieve cost-effective long-term data retention. The network layer adopts a dedicated line + VPN dual-link design, ensuring reliability of cross-cloud network connectivity.
3.2 Architecture Key Points
Production (AWS China): Deploy production environment (PRD) 4 hosts (2 ABAP APP + 2 SAP HANA DB), adopting high-availability architecture with application layer active-active and database layer active-active. Also deploy non-production environments (ECC, QAS) 4 hosts. Deploy independent Agentless conversion node, directly reading underlying storage via agentless method, avoiding impact on production environment.
DR (Alibaba Cloud China): Deploy HyperBDR console, responsible for global scheduling, policy configuration, and disaster recovery drill command. Target environment supports startup of SAP systems (ABAP + HANA), ensuring compatibility with source system. Deploy object storage (OSS) as disaster recovery storage for host-level data, deploy file storage (NAS) as disaster recovery storage for file-level data.
Storage Layer: Adopt dual-layer data synchronization architecture, host-level data synchronized through object storage (OSS), file-level data synchronized through file storage (NAS). Object storage as intermediate medium, significantly reducing storage costs, supporting long-term retention of SAP system data.
Replication: Configure policy-based synchronization, supporting regular backup and manual synchronization. RPO < 24 hours, RTO < 5 hours. Data replication process is continuous, providing data foundation for subsequent drills and takeover.
Network Layer: Connect local data center, AWS and Alibaba Cloud through dedicated line, achieving cross-cloud network connectivity. Reserve VPN as backup link when dedicated line is abnormal, ensuring network reliability.

4. Implementation & DR Drill Best Practices
4.1 Data Replication Phase
In the data replication phase before drills, this project adopts a dual-layer data synchronization architecture:
File-Level Synchronization (EFS → NAS): File data of each system (PRD/ECC/QAS) on AWS side synchronizes to EFS, synchronizes EFS data to Alibaba Cloud NAS through dedicated line. NAS serves as disaster recovery storage for file-level data, ensuring integrity and consistency of file data.
Host-Level Disaster Recovery Replication (Agentless → OSS): Agentless node reads underlying storage of each host, synchronizes data to Alibaba Cloud object storage OSS through dedicated line. OSS serves as disaster recovery storage for host-level data, supporting long-term retention of SAP system data.
Policy-Based Synchronization: Based on RPO < 24 hours requirement, flexibly configuring synchronization strategies, supporting regular backup and manual synchronization. Data replication process is continuous, providing data foundation for subsequent drills and takeover.
