Introduction
Standard Background and Financial Industry Value
With the acceleration of the transformation of distributed architecture in the financial industry, the proportion of distributed database applications in core business systems has increased from 12% in 2018 to 43% in 2022 (Central Bank Technology Department 2022 Annual Report). As one of the three major components of the distributed database technology financial application series standards, this specification, together with technical architecture and security requirements, constitutes a financial-grade distributed database technology standard system.
Disaster Recovery Capability Grading System
| Disaster Recovery Level | Applicable Scenarios | RTO Requirements | Data Copy Requirements |
|---|---|---|---|
| Level 4 | Impact on Financial Equity Business | ≤30 minutes | 1 copy in the same city/different location |
| Level 5 | Important Payment and Clearing System | ≤15 minutes | 2 copies in the same city + 1 copy in different location |
| Level 6 | National Financial Infrastructure | ≤1 minute | Six replicas in three locations |
Typical application cases
A national commercial bank adopted a 5-level disaster recovery standard in the transformation of its core accounting system:
1. The active-active center in the same city deploys a GoldenDB cluster with RPO=0
2. The remote disaster recovery center maintains data synchronization through logical replication
3. Quarterly practical exercises verify the 15-minute switching capability
Analysis of key technical requirements
Seven core control points
- Data synchronization mechanism: Level 4 and above require at least one synchronous replication copy
- Network bandwidth: The backup channel must be greater than the peak bandwidth of the business
- System compatibility: The hardware configuration of the disaster recovery center is 100% compatible with the production environment
- Monitoring system: A unified monitoring platform for the three centers must be implemented
- Drill frequency: Annual full-link drill + quarterly special drill
- Audit requirements: Disaster recovery plans must be filed annually and fully audited every three years
- Data verification: Establish an MD5+SHA256 dual verification mechanism
Implementation suggestions
Four-stage promotion path
| Phase | Key tasks | Cycle |
|---|---|---|
| Gap analysis | Conduct current status assessment against standards | 2-4 weeks |
| Scheme design | Develop disaster recovery level mapping table | 4-8 weeks |
| Construction implementation | Subsystem transformation and testing | 3-6 months |
| Continuous operation | Establish a normalized drill mechanism | Continuous |
Special note: For institutions using distributed databases such as TiDB and OceanBase, it is necessary to focus on the verification of the matching degree between the multi-copy consistency protocol and the standard requirements.
