Hangzhou Enterprise Data Backup | Siwenlide: 14 Years, 1000+ Clients

A Hangzhou Tech Company’s Worst-Case Scenario

Last October, a software outsourcing firm in Hangzhou’s Binjiang District that had been in business for six years had an IT administrator who routinely kept the code repository on a RAID 5 server. At three in the morning the server raised an alert: two drives had failed at the same time. The vendor said data recovery would take two weeks and start at RMB 150,000. Worse still, three projects were right at their delivery deadlines, and the client contracts stated in black and white that the contractor bears full responsibility for delays.

By the time this company came to us, the whole team had gone three days without sleep, trying every method they could think of to recover the original data. I asked them, “Have you ever run a recovery drill?” They shook their heads with a bitter smile. This kind of “running naked” situation is not uncommon among our clients in Wangjing and Changping either — most owners simply assume bad luck will never land on them.

Hangzhou’s industrial base is dominated by e-commerce, cloud computing, and manufacturing, and data assets are often the single most critical thing a company owns. Source code, design files, production formulas, customer records — lose any of these and you either pay a fortune to recover them or shut the doors. Siwenlide has provided fully managed IT Operations Outsourcing in Beijing for 12 years and has served Hangzhou clients formally since 2019. We currently have 23 enterprises in Hangzhou on long-term contracts, and data backup is one of our most frequently requested services. Our solutions avoid flashy features and focus instead on making “recovery when something goes wrong” 99.9% available.

Why Choose Siwenlide for Data Backup

Data backup products on the market are countless, from free open-source scripts to storage arrays costing hundreds of thousands of yuan. For small and mid-sized businesses in Hangzhou, the core question is not which software to buy, but who takes charge when something goes wrong.

We use the industry-recognized 3-2-1 backup strategy: three copies of the data, on two different types of media, with one copy stored off-site. The principle is simple to state but full of pitfalls in practice — when drives in the local NAS should be replaced, whether off-site bandwidth is enough to finish the overnight sync, who holds the encryption keys for cloud data, and whether ransomware that encrypts the NAS can be detected. There are no standard answers; the right design depends on each company’s business continuity requirements and budget.

Data backup is not a one-off project but a long-term commitment. Many clients buy a NAS and enable cloud storage but never verify whether they could actually get their data back if it were lost. We make backup verification a standard part of quarterly inspections, and each drill produces a report sent to the client’s technical lead. For several Hangzhou clients, this practice has become a point in their favor during internal audits.

In addition, our solutions can extend sTrust Zero Trust Security capabilities to stop ransomware from spreading laterally across the internal network. If you are interested, see the zero trust protection case study we delivered for a manufacturing client.

What We Did: Two Real Solutions for Hangzhou Clients

A fashion e-commerce company in Yuhang, Hangzhou, with a team of 30, whose core assets are its ERP system and product image library. They had been using a single Synology NAS plus manual copying to external drives. A drive had already failed once, though fortunately it did not die completely. Their pain point: the image library grows quickly (about 200 GB per month), and manual backups became harder and harder to sustain — during busy stretches a full week would go by without one.

We designed a solution with automatic local NAS synchronization and incremental archiving to cloud object storage, paired with a scheduled snapshot policy and a recovery point objective of four hours. Backup jobs now complete automatically every month, and the owner no longer has to worry about whether today’s backup was done.

Another client is a manufacturer in Xiaoshan with more than 50 employees. Its core business system runs on a local server holding a large volume of CAD drawings and production process documents. The biggest hidden risks: the server had only RAID 1, and the equipment room relied on ordinary residential air conditioning, with summer temperatures easily hitting 35°C. What worried them more was that the ERP vendor had become unreachable three years earlier — meaning the system had been running unsupported for three years.

Core Deliverables: What You Get

What we deliver to every data backup client is not a pile of equipment and accounts, but protection that actually works. Specifically:

1. Backup strategy design and implementation: tier systems by business criticality, set RPO and RTO targets, and configure the complete chain of local NAS, off-site backup, and cloud archiving.
2. Hardware supply and maintenance: we provide the NAS or backup appliance; failures during the contract term are replaced with new units at no extra cost.
3. Daily monitoring and alerting: backup job status, storage capacity, and drive health are brought under monitoring, with automatic notification to our engineers when anomalies appear.
4. Quarterly backup drills: each quarter we restore selected critical data in a test, produce a drill report, and confirm the backups really work.
5. Emergency response and disaster recovery: when data loss occurs, our engineers help assess the situation, define a recovery plan, and carry it out to reduce business downtime.

If your business demands higher continuity, you can bundle network equipment and security into a single package; we provide end-to-end service from design and implementation through operations. Learn more about our Network Equipment Package

Pricing Guide

The cost of a data backup service depends mainly on data volume, backup frequency, and recovery time requirements. Below are reference price ranges for several common scenarios; the final solution requires an assessment on our side:

※ The quotes above include hardware rental and IT operations service fees, and exclude emergency data recovery costs. Contract terms are typically 1-3 years; longer commitments qualify for a discount.

Frequently Asked Questions

Q: Our data is already in the cloud — does that mean we don’t need local backups?

Cloud platforms are designed for high availability, but regional outages do happen. Last year a major provider’s cloud storage went down for more than 24 hours, and throughout the recovery every business depending on that system was at a standstill. More common still is human error — data deleted in the cloud, recycle bins emptied, and sometimes nothing can be recovered. A local backup provides a “last usable copy” that complements the cloud. My recommendation: even if your business runs entirely in the cloud, keep a local snapshot.

Q: We bought a NAS and set up backups — are we fully covered?

Not necessarily. The NAS itself can fail, hard drives have a limited lifespan, and today’s ransomware specifically targets network storage. I have seen several clients whose NAS was locked down and data encrypted, backups included. Keep the NAS off the public internet, tighten access permissions, and where possible add multi-version snapshots and offline copies. Siwenlide’s solutions take all of this into account — if you have specific questions, you can contact our engineers directly.

Q: If we really lose data, can you guarantee a full recovery?

No solution can promise 100% recovery, but a 3-2-1 strategy reduces risk to a minimum. If the backups themselves are intact, the recovery success rate depends on why the data was lost — accidental deletion is usually recoverable in full, while hardware failure depends on the extent of the damage. On recovery time, a local NAS can take as little as a few hours, while off-site cloud may take one to two days. We will spell out the realistic recovery expectations for each data set in the drill report — no inflated promises.
