As the first heavy machinery manufacturer independently designed and built in New China, Taiyuan Heavy Machinery Group Co., Ltd. (TZ Group), founded in 1950, is known as a “pioneer of the national economy.” After more than 70 years of development, TZ Group has grown into a large state-owned enterprise covering heavy machinery manufacturing, rail transit equipment, hydraulic industries, and more—creating over 500 “firsts” in China and worldwide, and holding a core position in major national equipment manufacturing.
With deepening digital transformation, the Group’s business systems have become increasingly complex, and the value of core data has grown significantly. Data security and business continuity have become fundamental pillars supporting high-quality development.
The Urgent Need for Disaster Recovery in Digital Transformation
Key subsidiaries, including Taiyuan Heavy Industry Co., Ltd. and Taiyuan Heavy Industry Rail Transit Equipment Co., Ltd., have implemented digital systems across finance, office collaboration, and workshop production. Core databases run on SAP HANA deployed on physical servers, while other business systems operate across multiple virtualization platforms such as VMware, Sangfor HCI, and H3C CAS.
As production scale expanded and data volumes surged, TZ Group faced multiple data security challenges:
-
Core business data—especially SAP HANA databases—supports production scheduling and financial accounting. Any loss or corruption would result in severe consequences.
-
Business systems running on diverse virtualization platforms lacked unified backup protection, leaving them vulnerable to single-point failures, human errors, and ransomware threats.
-
As a state-owned enterprise, TZ Group must comply with China’s Data Security Law and national disaster recovery standards, requiring a compliant and reliable DR framework.
Against this backdrop, TZ Group urgently needed a comprehensive, efficient, and flexible disaster recovery solution to safeguard its digital transformation journey.
Layered Protection + Unified Management: Building a Full-Scenario DR System
Based on TZ Group’s business characteristics and DR requirements, Info2soft delivered a phased, customized solution built on:
-
Real-time protection for core data
-
Agentless VM backup
-
Unified disaster recovery management
This architecture ensures full lifecycle data protection and rapid business restoration.
Real-Time Protection for Core Data, Near-Zero RPO
For mission-critical databases such as SAP HANA, Info2soft’s i2CDP Continuous Data Protection technology enables real-time data replication and recovery to any point in time.
Two Info2soft backup appliances were deployed in an active-standby cluster with shared storage to provide high availability. Production data changes are transmitted to the DR site in real time, with every modification logged for precise recovery.
Key advantages include:
-
Byte-level incremental capture, transmitting only changed data blocks to reduce bandwidth consumption
-
Flexible CDP policies supporting:
-
Any point-in-time recovery within 7 days
-
Daily recovery within 30 days
-
Monthly recovery within 180 days
-
-
Rapid rollback in the event of ransomware or logical errors
This ensures data loss risk approaches zero.
Agentless VM Backup for Simplified Operations
For nearly 500 virtual machines across VMware, H3C CAS, and other platforms, Info2soft’s i2VP virtualization backup software provides agentless full-machine protection.
Without installing agents inside VMs, backups are executed at the host layer, supporting full, differential, and incremental backup strategies.
Highlights include:
-
LAN-Free high-speed transmission to reduce production network load
-
Concurrent backup of multiple VMs within minutes in 10Gb NAS environments
-
Flexible recovery options:
-
Standard recovery
-
Instant recovery (TB-level VMs can start within minutes)
-
Cross-platform restoration
-
These capabilities significantly shorten Recovery Time Objectives (RTO) and enable rapid business takeover.
Unified DR Management Platform: Full Visibility and Control
Info2soft deployed the i2UP unified DR management platform to centrally manage real-time database backup and agentless VM backup.
Through a fully graphical web interface, administrators can:
-
Monitor backup task status
-
Track synchronization progress
-
View device health in real time
The platform supports cross-domain resource management, role-based access control, template-based backup policies, remote agent deployment, and automated email alerts.
It also supports migration modes such as P2P, P2V, and V2V, laying the foundation for future cross-data-center DR (metro-level DR) expansion and sustainable system upgrades.
High-Availability Architecture for DR System Reliability
The backup appliance cluster adopts an active-standby HA model with shared NAS storage.
If the primary node fails, services automatically switch to the standby node without interrupting backup tasks. This design eliminates single points of failure within the DR system itself, further strengthening overall reliability.
Technical Innovation and Practical Value
1. Layered Backup Strategy
Real-time backup for core data, scheduled backup for non-core systems, and agentless full-VM backup ensure optimized resource allocation and cost efficiency.
2. Multi-Platform Compatibility
Supports SAP HANA, Oracle, MySQL, VMware, H3C CAS, and more—perfectly adapting to TZ Group’s heterogeneous IT environment without requiring system restructuring.
3. Simplified Operations
Agentless backup reduces maintenance overhead, while centralized management enables one-stop DR control, allowing IT teams to focus on strategic business initiatives.
From “Passive Backup” to “Proactive Protection”
Comprehensive Data Security:
CDP ensures precise point-in-time recovery for SAP HANA core data, while full-VM backup protects all business systems against hardware failure, human error, and ransomware.
Significantly Enhanced Business Continuity:
Instant VM recovery and rapid database restoration reduce downtime to minutes, ensuring uninterrupted production scheduling, financial accounting, and collaboration.
Improved Operational Efficiency:
Unified management and automation reduce manual intervention, lowering costs while improving reliability.
Solid Foundation for Digital Transformation:
A compliant and reliable DR system supports current operations and future expansion, including cross-data-center disaster recovery initiatives.
As a professional vendor specializing in data replication and disaster recovery, Info2soft has delivered reliable DR solutions to numerous large state-owned enterprises.
The successful collaboration with Taiyuan Heavy Machinery Group Co., Ltd. marks another benchmark case in the SOE sector, demonstrating Info2soft’s technical adaptability and customization capabilities in complex IT environments.
Looking ahead, Info2soft will continue advancing DR innovation and building stronger security foundations for enterprise digital transformation worldwide.
