In September 2023, a precision-parts export manufacturer in Shajing, Shenzhen, lost three months of ERP data through an employee error, and its production line was forced to halt. The owner ran the numbers: every day of downtime cost more than RMB 80,000. He called at midnight. We urgently dispatched engineers from Beijing, coordinated with our local Shenzhen partner, applied a 3-2-1 backup strategy, and had the data recovered and systems back online within 6 hours. That incident made one thing clear to me: many manufacturing companies in Shenzhen do not lack backup awareness — their backup plans are simply sloppy. Either the backup drive sits in the same cabinet as the source drive, or the backup schedule is “whenever someone remembers to do it.” This article is written for Shenzhen business owners and IT managers, to set out clearly what enterprise data backup really involves.

Why Shenzhen Companies Choose Siwenlide for Enterprise Data Backup

We have delivered 14 years of IT services in Beijing, serving 1000+ enterprise clients, and began formally serving the Shenzhen market in 2019. Not because we expanded slowly, but because in the early years we were focused on refining our products and standardizing our processes. The backup solutions we now provide to Shenzhen companies use the same system as those we provide to Beijing clients. The difference is that we have local partners in Shenzhen for on-site support, so our response speed is no slower than that of a local company.

There are just three core reasons Shenzhen companies choose us:

1. Localized rapid response: Beijing handles solution design, our Shenzhen partner handles on-site implementation, and we respond to Shenzhen clients within 2 hours. We have run this cadence for 4 years and it is now mature.
2. The 3-2-1 backup strategy, genuinely implemented: buying a NAS and plugging it in is not a backup. What we deliver is real-time local NAS synchronization + an off-site backup appliance + cloud archiving — three copies of data on three different media, so that if any one fails, recovery is still possible.
3. Proactive ransomware defense: in 2023 we helped two Shenzhen companies avoid ransomware attacks. The ransomware group encrypted their file servers, but the backup side was locked down — because we had implemented network isolation and access control, the backup data was untouched. We have since turned that experience into a product.

What We Have Done in Shenzhen

Two specific cases — not benchmark customers from a slide deck, but projects we genuinely delivered.

Case 1: a cross-border e-commerce company with 200 employees in Longhua. When this company came to us in 2022, their backup situation looked like this: they had bought a Synology NAS, their backup strategy was “manually back up once a week,” and the backup drive sat in the same cabinet as the source drive. I asked whether they had ever run a recovery drill, and the IT manager paused, then said, “I don’t think so.” That situation is actually very dangerous — a backup that has never been used is as good as no backup at all. After we came on board, we redesigned the solution: added an off-site backup appliance, deployed automated daily incremental backups, set up email alerting, and ran a recovery drill every quarter. In March 2023, a newly hired operations employee accidentally deleted 20,000 product main images. Because the backups were incremental, the previous day’s data was fully preserved, and everything was restored within 4 hours. Later, the owner told me that receiving a monthly backup status report now gives him real peace of mind. This client subsequently handed us their Network Equipment Package and IT Operations Outsourcing as well, and the scope of our work together keeps widening.

Case 2: a law firm with more than 80 people in Futian. A law firm’s data is highly sensitive — client trade secrets, case materials, contract documents — all of it must not leak. Their requirements were clear: data must not be lost, must not be accessible to unauthorized people, and must be recoverable quickly if something goes wrong. The solution we gave them was encrypted local storage + off-site disaster recovery + strict access permission management. There was an episode at the end of 2023: one of their partners wanted to test the team’s security awareness, deliberately sent a phishing email to employees, and then used the harvested account to try to delete core case files. The system triggered an alert immediately, the abnormal operation was blocked within 15 minutes, and the deleted files were automatically restored from backup. After that, the whole firm ran a company-wide security training session. You see, a backup solution is not just a technical matter — it also involves management processes and staff awareness.

Core Deliverables of Enterprise Data Backup

The deliverables list may vary slightly from project to project, but the following items are the standard configuration of our backup solutions:

1. 3-2-1 backup strategy planning and implementation: this is the core of the entire solution. One copy of the data is kept on the local NAS for real-time synchronization, one copy is placed on an off-site backup appliance to guard against local disaster, and one copy is uploaded to the cloud for archiving. Three copies, three media types, two geographic locations — a failure of any one does not affect overall recovery.
2. Local NAS storage deployment and tuning: we select models according to the company’s data volume and growth expectations — Synology, QNAP, Lenovo or Huawei all work; the key is that the configuration must be sound. RAID setup, backup software deployment, backup job scheduling — these are technical tasks, and doing them poorly causes a pile of trouble later.
3. Off-site disaster recovery design and implementation: where the off-site backup appliance is placed, how data is transmitted, whether transmission is encrypted, and how recovery proceeds after a disaster all need to be planned in advance. One of our Futian clients placed their backup appliance in another data center in Nanshan; the two sites are network-connected but physically isolated, and that configuration took considerable thought.
4. Cloud archiving and long-term retention: using Alibaba Cloud or Tencent Cloud object storage for compliance-driven data retention. Data such as financial ledgers and contract documents carries a 7-10 year retention requirement, and cloud archiving is the most reliable option. Data is encrypted before upload, you hold the keys yourself, and even the cloud provider cannot see your content.
5. Ransomware protection mechanisms: this is a module we added in recent years. The backup system must be able to identify abnormal file behavior — a normal backup does not encrypt files at scale, so any such activity triggers an immediate alert and block. We also isolate the backup appliance on the network. Ransomware trying to spread over the network to the backup side? No way.
6. Recovery drills and operations reports: a recovery drill every quarter, and an operations report every quarter. The report covers backup success rates, recovery test results, storage capacity trends, and a summary of abnormal events. Many clients do not care about this report at first, but once they get used to it they find it valuable — it gives them material for reporting to the boss and evidence for security audits.

Pricing Reference (Shenzhen)

Backup solutions cannot be quoted at a flat price, because every company’s server count, data volume, and network environment differ. But I can give a reference range so Shenzhen business owners have a sense of the numbers. The quotes below exclude cloud archiving fees; cloud storage is billed separately based on actual usage.

Company Size	Solution Tier	What’s Included	First-Year Cost Reference
50–100 employees 1–2 servers	Standard	3-2-1 strategy · local NAS · offsite backup · quarterly drills	From RMB 38,000/year
100–300 employees 3–5 servers	Professional	Standard + cloud archiving + ransomware protection + monthly drill reports	From RMB 68,000/year
300+ employees 5+ servers	Flagship	Professional + dedicated database backup + dedicated operations support + real-time monitoring dashboard	Custom quote

Actual projects are quoted after a combined assessment of the number of servers, database types, data volume, network architecture, and whether cloud archiving is required. These prices are only a starting reference. If your company runs a particularly large number of servers, or has a more complex database environment (such as Oracle or a SQL Server cluster), the cost will increase accordingly. We don’t play the low-bid game — a low quote means reduced service, and in the end it’s the business that pays for it.

Frequently Asked Questions

Q: How often should data be backed up?
There’s no standard answer — it depends on what your business systems actually need. For core systems such as ERP and finance software, we recommend real-time synchronization or hourly incremental backups. General file servers and code repositories can be backed up once a day. Employee workstations can use daily or weekly incremental backups. What matters isn’t how high the frequency is, but whether the backup data is regularly tested for restorability. I’ve seen clients who kept backing up for two years, only to find during a restore test that the backup files were corrupt. That kind of false sense of security is more dangerous than having no backup at all.

Q: How should data be backed up during a server migration?
Take a full backup before the migration, then synchronize data within a downtime window during the migration to keep downtime as short as possible. Our usual recommendation is: run a full backup before migrating; during the migration, stop writes, back up, migrate, verify, then resume writes. If you’re on a virtualization platform, you can take snapshots, which makes rollback easy. After the migration is complete, run a full data validation to confirm data integrity.

Q: What’s the relationship between backup and moving to the cloud? Which should we choose?
These are two different concepts. Backup means keeping a copy of your data so it can be restored if it’s lost; moving to the cloud means deploying your business systems on cloud servers — essentially a change of infrastructure. The two can certainly be combined: use cloud servers as a backup target, or back up on-premises data to the cloud for offsite disaster recovery. Which one to choose depends on your actual needs — if your local server room is limited, cloud-based offsite backup is a good option; if you have data sovereignty requirements, on-premises backup plus cloud archiving may be more suitable. Talk to us about your specific case and we’ll help you work out which combination fits best.

Q: After a ransomware attack, can the data still be recovered?
It depends. If the backup data was also encrypted or deleted by the ransomware, recovery is very difficult. If the backup data is network-isolated and the backup side was not infected, recovery is relatively straightforward. Our solution applies multiple layers of protection: the backup system monitors file changes and immediately alerts and blocks when abnormal encryption is detected; backup devices are network-isolated and do not communicate directly with the office network; and backup versions from multiple points in time are retained, so even if the latest backup is infected, you can still restore from an earlier clean version. Over the past two years we have handled ransomware incidents for 11 companies in Shenzhen, with a data recovery success rate of 100% — because their backup solutions were designed by us, with particularly solid network isolation.

As companies in Shenzhen pursue digital transformation, their data assets keep growing in value — yet many owners still treat data backup as nothing more than “buy a NAS and stick it in the office.” That’s understandable: backup is the kind of work whose value you can’t see when nothing goes wrong, and only appreciate once something does. What we can do is build the solution solidly, run the drills for real, and make sure recovery actually works. Shenzhen runs high volumes at a fast pace, and the bar for data security will only keep rising. If your company needs backup, we’d welcome a conversation — it doesn’t have to be a project; trading ideas is fine too.
