For international companies operating in Greater China, designing backup solutions within China is often not as straightforward as it initially appears. Restore speed, cross-border cloud access, and local data requirements all play a direct role in determining the effectiveness of a backup plan in real-world operations.
The real question is not whether data should be backed up, but where those backups should be kept and how quickly systems need to be restored to keep the business running.
Key Takeaways
- Start with the business: map each application to clear RTO and RPO targets before choosing tools or locations.
- For most international companies, a hybrid model works best: a fast local copy for restores plus an encrypted offsite copy for DR and retention.
- Match the backup method to the workload: replication or logs for databases, image backups for servers, versioned sync for files and endpoints.
- Protect recoverability with at least one immutable or air-gapped copy and prove it through regular restore testing with measured RTO/RPO.
- Localize designs for China network and compliance constraints, and validate restore speed and cost before relying on cloud-only models.
- JET IT Services supports assessment, pilot testing and ongoing operation of backup solutions in China, with local execution and multilingual engineers.
Backup Solutions Overview
This guide explains practical and commonly used backup solutions for international companies in China, including: what to protect, where to store copies, who should run backups, and how to keep operations auditable.
Term definitions:
- RTO (Recovery Time Objective): how long the business can tolerate downtime.
- RPO (Recovery Point Objective): how much data loss/time is acceptable.
- Disaster Recovery (DR): the processes and systems used to recover services after a major outage.
- Software-as-a-Service (SaaS): cloud apps like Microsoft 365 (M365).
What to Back up
Asset class | What to include | Baseline strategy |
End-user files & devices | Laptops, desktops, user home folders, Microsoft 365 | Continuous file sync or agent backups with versioning; |
Servers & virtual machines (VMs) | Hyper-V/VMware VMs, middleware, application hosts | Image-based backups (weekly fulls + daily incrementals), local |
Databases & transactional systems | SQL Server, MySQL, Oracle, Enterprise Resource Planning | Full + frequent transaction log backups or continuous replication |
SaaS (Microsoft 365) | Exchange mailboxes, OneDrive, SharePoint, Teams | Third-party API-driven backup scheduled daily (or more often for |
(These are baseline recommendations —always tune to business RTO/RPO.)
Where Data is Stored
Match each application’s RTO, RPO, and legal/compliance constraints to a storage tier:
On-premises (local primary copy)
- Network Attached Storage (NAS) or Storage Area Network (SAN) with snapshots — fastest restores and predictable behavior. Keep at least one short-term local copy to avoid cross-border restore delays.
Cloud (offsite secondary / DR / archive)
- Good for long retention and geographic resilience. Important: validate restore speeds over China links before relying on cloud for tight RTOs.
Hybrid
- Local primary + encrypted cloud secondary
- Recommended for most international operations in China.
Regulatory note: China has tightened rules on cross-border transfers of personal data and introduced certification/assessment mechanisms for exports. If your backup plan moves personal information or “important data” outside the mainland, factor in certification, contractual or security assessment requirements. These rules are actively evolving; treat cross-border transfer as a compliance question as well as a technical one.
Who Manages Backups
Self-managed (in-house)
- Pros: direct control and visibility.
- Cons: requires local 24×7 runbooks and IT staff.
- Choose this if you have local operations and audit capability.
Managed backup service (outsourced)
- Pros: local execution, Service Level Agreements (SLAs), predictable staffing.
- Cons: less direct control; choose IT partners with proven local presence and escalation processes.
Hybrid (policy in-house, execution outsourced)
- Pros: governance stays internal while local partners handle operations; often the best fit for international companies wanting oversight and local delivery.
Decision tip: If you cannot validate a restore within your RTO over local network links, favour managed or hybrid options with a local escalation path.
Backup Methods & Strategies for IT Teams
- Full backups: a complete copy; baseline for retention.
- Incremental backups: capture changes since the last backup; reduce backup window and storage.
- Differential backups: capture changes since last full; simpler restore chain than many incrementals.
- Snapshots: fast point-in-time images on storage for quick local rollback — not a substitute for long-term backups.
- Image-based backups: full system/VM images for bare-metal recovery.
- Transaction log capture / continuous replication: required for databases needing tight RPO and point-in-time recovery.
For SaaS such as Microsoft 365, use purpose-built API-based backup tools and keep an independent copy — don’t rely solely on vendor retention windows. See Microsoft guidance for its backup solutions.
Practical Frequency Checklist for IT Teams
This checklist is intended for IT teams implementing and operating backup policies.
Always define RPO and RTO per application first. The table below provides a pragmatic baseline commonly used by international operations in China and should be validated through restoring testing.
App criticality | Example RPO target (time-based) | Example schedule |
Mission-critical DB (ERP / finance) | Near-zero to 15 minutes | Continuous replication or transaction log backups every 5–15 minutes; nightly full if required |
Server VMs (application hosts) | 4 to 24 hours | Weekly full image + daily incrementals; snapshots every 4–12 hours when supported |
File shares / team drives | 1 to 24 hours | Continuous or hourly incrementals with nightly full baseline |
End-user files | Minutes to 24 hours | Continuous file sync or versioned backups, plus nightly backups |
SaaS (Microsoft 365) | Up to 1 day (shorter for critical sites) | Daily full snapshots with more frequent incrementals for critical mailboxes or sites |
Pre-deployment checklist
- Map RTO/RPO and get stakeholder sign-off.
- Validate China network bandwidth and test restore speeds.
- Ensure immutability or offline copies for ransomware protection (Write Once Read Many — WORM).
- Confirm key management and any legal restrictions (Bring Your Own Key — BYOK options where needed).
Restore verification schedule
- Monthly: automated verification and quick application-level checks.
- Quarterly: full restore drill for at least one critical system.
- Annually: end-to-end DR test with stakeholders.
Common Mistakes to Avoid in Deployments
- Designing for cloud only, assuming fast restores in China.
How to avoid: Test restores over your China network paths and validate RTO/RPO under realistic load.
- Buying backup software without restore verification or runbook drills.
How to avoid: Enable automated restore checks, run monthly quick restores and keep an updated runbook.
- No immutable or air-gapped copy against ransomware and unauthorized access.
How to avoid: Keep an immutable/offline copy, enforce least-privilege and MFA for backup ops, and test restores from that copy.
- Applying global templates without local adjustments.
How to avoid: Localize schedules/retention for bandwidth and compliance; run an in-region pilot before roll-out.

FAQ
- What are the best backup solutions in China for foreign companies?
Hybrid deployments that keep local primary copies for fast restores and an encrypted offsite secondary (for DR and long retention) are the most practical approach. Always keep at least one immutable or offline copy.
2. How often should I back up my database?
Decide RPO first. For transactional databases, use frequent transaction log backups or continuous replication (e.g., logs every 5–15 minutes) to enable point-in-time recovery, plus regular full backups as appropriate.
3. Is pure cloud backup practical?
Cloud is practical for DR and long-term archives, but you must test restores over China links if you need tight RTOs. For fast restores, retain a local copy or cache.
4. Which vendors support backup in China well?
Choose vendors with a strong partner ecosystem and proven in-region restore workflows. Examples frequently used by international firms include Veeam and Commvault, combined with local partner delivery and major cloud providers.
5. What is the 3-2-1 rule and should I follow it?
Keep three copies of data, on two different media, with one copy offsite. Yes, it is a solid baseline and fits well with hybrid strategies.
6. How do I protect backups from ransomware?
Use immutability/WORM, air-gapped or offline copies, least-privilege access controls for backup systems, periodic verification, and segregated credentials for restore operations.
7. How do I test if backups are recoverable?
Run scheduled restore drills, document steps, test application-level restores, and measure the measured RTO/RPO against targets. Include both automated verification and periodic full restores.
8. What retention policy should I use?
Retention depends on compliance and business needs. Typical patterns: short-term (daily/weekly), medium-term (monthly), and long-term (yearly) archives. Tune to legal retention requirements and cost models.
9. Can I keep encryption keys outside China?
Key management depends on vendor capability and legal constraints. Some providers support BYOK; always check contractual terms and compliance impacts before placing keys offshore.
10. What hidden costs appear in backup contracts?
Watch for egress and restore charges, API call costs, cold-storage transition fees and fees for large-scale restores. Get a realistic cost estimate for your expected restore profile.
11. How do I back up Microsoft 365 data?
Use a third-party API-driven backup tool to keep an independent copy, and retain backups beyond vendor default retention windows for critical mailboxes and sites.
12. Do I need a backup audit?
Yes. Regular audits validate configuration and restoreability; they are recommended for regulated industries and enterprises with cross-border data flows.
