1. Overview: Why use mirroring and backup on the Vietnam node

• Alibaba Cloud offers local ECS and snapshot mirroring services in Vietnam (VN), suitable for business deployment targeting users in Vietnam and Southeast Asia.
• Images are used for rapid deployment of a consistent environment, while backups are used for long-term data protection and compliance archiving.
• Combining CDN with Anti-DDoS can reduce impact during attacks and improve availability.
• Common targets: RPO ≤ 15 minutes, RTO ≤ 30 minutes to ensure e-commerce/media business.
• Cost and performance must be balanced: Coexisting local cold backup with cross-regional hot backup can achieve optimal cost.

2. Mirroring and snapshot strategy design

• It is recommended to use a timed snapshot (incremental) + daily full mirroring strategy for the main instance: incremental snapshots every 15 minutes, full mirroring once daily at midnight.
• Snapshots are taken separately from the system disk and data disk; the system disk is retained for 30 days, and the data disk for 90 days.
• Snapshot storage uses Alibaba Cloud OSS archiving or standard storage for tiered management, saving long-term costs.
• For databases, use dual-track logical backup + physical snapshots to ensure consistency.
• Automation: Trigger snapshots and write backup logs using API/SDK to support audit and recovery drills.

3. Recovery drills and Recovery Time Objectives (RTO/RPO) practices

• Example of goal setting: RPO = 15 minutes, RTO = 30 minutes.
• Recovery steps include: quickly creating ECS from the image→ recovering additional data disk snapshots→ switching load balancing and DNS.
• Practical Exercises: Conduct a full recovery drill once a month during non-business hours, recording average RTO for optimization.
• Using Alibaba Cloud image acceleration can reduce image import and export times, with typical recovery rates increasing by 30%-50%.
• Integrates with CDN and Anti-DDoS to maintain user access experience through edge caching during switchovers.

4. Real-life case: Recovery process for a Vietnamese e-commerce platform failure

• Background: A Vietnamese e-commerce company experienced a server failure and a DDoS attack during the Double 11 shopping festival.
• Original configuration: Prod ECS ecs.c6.large (2 vCPU, 8GB), system disk 40GB, data disk 200GB, public bandwidth 100Mbps.
• Solution: Real-time incremental snapshots + cross-region cold standby, CDN caching enabled and Anti-DDoS Pro protection enabled.
• Recovery results: RPO reached 10 minutes, RTO averaged 22 minutes, and business resumed after peak traffic mitigated to 60% of normal.
• Cost comparison: During peak periods, additional protection and snapshot costs for this solution account for about 6%~8% of total operating expenses.

5. Configuration example table and cost/performance comparison

environment instance model CPU memory system disk public network bandwidth
production (VN). ecs.c6.large 2 vCPU 8 GB 40 GB SSD 100 Mbps
Hot standby (adjacent area). ecs.g6.large 2 vCPU 8 GB 40 GB SSD 50 Mbps
cold standby (cross-region OSS + snapshot). storage scheme -- -- snapshot 200 GB (increments). archive/restore on demand
• Instances in the table are configured as examples and can scale vertically according to concurrency and business types.
• It is recommended to enable both Alibaba Cloud CDN and Anti-DDoS Pro, with an SLA typically reaching 99.95%.
• Cost estimate: Scheduled incremental snapshots + daily mirroring + Anti-DDoS increase overall costs by about 5%~10% per month during peak periods.
• Recommendation: Automatically trigger failover and record recovery metrics using basic monitoring (CloudMonitor).
• Summary: By combining mirroring, snapshots, cross-zone cold/hot standby, and edge protection, quantifiable RPO/RTO targets can be achieved at the Vietnam node, significantly enhancing business recovery capabilities.
