Last winter, an auto parts manufacturer in Shunyi, Beijing, ran into serious trouble. Ransomware infected their ERP server, locking down financial, inventory, and production scheduling data. Zhang, the IT manager, recalls that the most desperate moment was not the encryption itself, but the discovery that their only “backup” was a portable hard drive — last copied three months earlier. It took a full week to piece historical data back together from various departments, and the production line shutdown cost more than RMB 800,000. This client later came to Siwenlide and deployed the 3-2-1 backup solution we recommended. The following year, an employee accidentally deleted a core database — and a full recovery was completed within two hours. In this industry, backup always looks like a luxury until something goes wrong, and by then it is too late for regret.

Why Beijing Enterprises Choose Siwenlide for Enterprise Data Backup

After fourteen years in data backup, I have seen far too many companies treat it as “copy it when I remember, skip it when I don’t.” What Siwenlide does is not sell equipment — it is help enterprises build a disaster recovery system that genuinely works. We follow the internationally established 3-2-1 backup strategy: at least 3 copies of data, on 2 different types of media, with 1 copy kept off-site. This is paired with high-speed recovery from local NAS, dual safeguards through cloud disaster recovery, and dedicated ransomware protection — encryption activity can be blocked right at the backup layer.

1. 3-2-1 three-tier architecture: local, off-site, and cloud: Local NAS guarantees recovery within 15 minutes, off-site disaster recovery nodes handle regional disasters, and cloud archiving preserves historical versions. Three layers in one, with no blind spots.
2. Dedicated ransomware protection: Backup data is immutable by default and cannot be altered. Even if an administrator account is compromised, ransomware cannot encrypt the backups. Combined with real-time behavior monitoring, anomalous access triggers alerts within seconds.
3. Quarterly recovery drill program: Completing a backup is not the end of the job — it must be proven usable. Siwenlide runs a full recovery drill every quarter, provides a written report, and keeps it on file.

What We Have Done in Beijing

That auto parts company in Shunyi, with annual revenue of more than RMB 300 million, is a typical case. When it suffered a ransomware attack in December 2023, its ERP, MES, and financial systems all went down. The first thing we did on site was not install software — it was map out their data assets. It turned out that their “backup” was a portable hard drive manually copied once a week, untouched for three months. Siwenlide deployed a local NAS for hourly incremental backups, leased a disaster recovery data center node in Changping, Beijing, and set up cloud archiving to Alibaba Cloud North China 2. Three months after implementation, they faced a real ransomware attempt — an employee clicked a phishing email that triggered the spread of the virus, but the backup system detected the anomalous behavior at 2 a.m. and triggered isolation. Three hours later, no data loss was confirmed. The client later told us this was the first time they felt that “backup really works.”

Core Deliverables of Enterprise Data Backup

1. 3-2-1 backup strategy planning and implementation: Based on the enterprise’s data types, data volume, and RTO/RPO requirements, we tailor a three-tier architecture of local NAS, off-site disaster recovery, and cloud archiving. We are not selling equipment; we are helping enterprises build a complete disaster recovery system.
2. Local NAS / all-flash array deployment: Hardware installation, system commissioning, backup software deployment, backup policy configuration, retention period settings, and monitoring and alerting configuration are all included in the scope of delivery.
3. Off-site disaster recovery center build-out: Siwenlide operates its own data center node in Changping, Beijing, enabling rapid activation of off-site backup channels. Data is transmitted encrypted and stored encrypted on arrival, with support for cross-region disaster recovery drills.
4. Cloud archiving services: We integrate with major providers such as Alibaba Cloud North China 2 and Tencent Cloud North China, supporting multiple policies including one-year retention, three-year retention, and permanent archiving. Archived data is read-only by default and cannot be deleted.
5. Dedicated ransomware protection: Backup data is protected by immutable read-only locks, so ransomware attacks cannot encrypt backup copies; anomalous access behavior triggers real-time alerts, and unusual calls to the backup system are notified within seconds.
6. Quarterly recovery drills: A full recovery drill is performed every quarter, covering three scenarios: file-level recovery, point-in-time database recovery, and disaster failover. The entire drill is recorded, and the recovery report is archived.

Pricing Reference (Beijing)

The cost of data backup depends mainly on two factors: company size and the complexity of the backup strategy. A 50-person company and a 300-person company may differ by more than tenfold in data volume, and their number of backup nodes, drill frequency, and compliance requirements all differ. Siwenlide’s pricing is packaged on a per-user annual basis — the more users, the lower the unit price.

Company Size	Typical Data Volume	Backup Nodes	Reference Monthly Fee Range
50-100 employees	3-5TB	2-3 nodes	RMB 3,000–5,000/month
100-300 employees	10-20TB	4-6 nodes	RMB 8,000–15,000/month
300+ employees / finance & healthcare	30TB and above	Custom solution	RMB 20,000+/month

Frequently Asked Questions

Q: Will backups affect the performance of our business systems?

I have been asked this question for over a decade. The answer is: it depends on how you do it. Siwenlide uses LAN-Free backup technology, in which the backup process runs on a dedicated network channel and does not compete with business traffic for bandwidth. Measured impact on the performance of core systems such as ERP and databases is kept within 5%, and everyday office work is essentially unaffected. The choice of backup window also matters — we usually recommend nights or weekends, avoiding peak business hours.

Q: If we really do get hit by ransomware, can the data be recovered? How long does recovery take?

Yes — provided the backup architecture is designed correctly. In Siwenlide’s solution, offsite backup and cloud archiving are isolated zones that ransomware cannot reach. Even if every local system is compromised, data can be pulled from the offsite node for recovery. Recovery time depends on data volume and architectural complexity: ordinary office systems can be back up and running within 2–4 hours, and core databases can be restored to the most recent point in time, typically within 8 hours. We commit to an SLA, with compensation terms if recovery exceeds the agreed time.

Q: Is our data safe with you? How do you ensure compliance?

Data security is the bottom line. All Siwenlide backup data is protected with AES-256 encryption in transit and at rest. Backup media are stored in the company’s own Changping data center or Alibaba Cloud’s North China nodes; there is no cross-border transfer. Our contracts explicitly include data confidentiality clauses, we provide annual compliance reports, and we support enterprises in meeting MLPS 2.0 (China’s Multi-Level Protection Scheme) or ISO 27001 requirements. For biopharmaceutical and financial clients, the compliance projects we have delivered are all backed by written case studies available for review.

Q: Once backups are in place, how do we know they can actually be restored?

Backups that are never tested are as good as no backups at all. Siwenlide runs a full recovery drill once every quarter, covering three scenarios: file-level recovery, point-in-time database recovery, and disaster failover. The entire drill is recorded on video, and recovery reports are archived for audit review. Some clients ask for an SLA clause in the contract that measures “recovery success rate”; we accommodate that as well. We have seen too many enterprises that ran backups for three to five years and only discovered on their first attempted restore that the paths had been configured incorrectly — all that time wasted on troubleshooting. Our goal is simple: whether backups are done well should be settled by the drill data.
