A machining factory in Chengdu’s Shuangliu District, run by an owner who had been in business for twelve years, was hit by ransomware last summer. When the engineers powered up their machines that morning, the drawings would not open, and the ERP and CRM on the server were locked. The attackers demanded 150,000 — more than the company’s profit for the month. With no offline backup of any kind, the team had no choice but to re-enter everything from the last manually exported Excel file from before the crash. The production schedule slipped by two weeks and the loss came to nearly 400,000. This is not a story; it is a lesson that actually happened to one of Beijing Siwenlide’s customers in Chengdu. Data is invisible and intangible in normal times — you only learn its weight when something goes wrong.

Why Chengdu Enterprises Choose Siwenlide for Enterprise Data Backup

Siwenlide has delivered IT operations services in Beijing for fourteen years, serving 1,000+ enterprise clients, with multiple partner enterprises in Chengdu and Southwest China as well. We have built a complete methodology around data backup, centered on the internationally recognized 3-2-1 backup strategy — 3 copies, 2 media types, 1 offsite. This architecture addresses disk failure, accidental deletion, ransomware attacks, and regional power outages at the same time. Combined with local NAS, offsite disaster recovery nodes, and cloud archiving, we build a multi-layered protection framework for Chengdu enterprises.

In Chengdu we do more than backup — we also provide full IT operations outsourcing.

1. 3-2-1 architecture, a textbook-grade backup strategy: real-time snapshots on local NAS + weekly synchronization to an offsite data center + cloud archival storage — three lines of defense. Even if ransomware encrypts your local files, the attacker cannot reach your offsite backups.
2. Integrated ransomware protection, more than backup: backup is the last line of defense, but the best defense is to act first. We integrate the sTrust zero trust solution (Learn more) to restrict the execution of suspicious processes and contain lateral movement inside the network, so ransomware cannot get in or spread.
3. Local team support, fast response: partner engineers are based in Chengdu and arrive on site within 2 hours for network issues. With two recovery drills every year, you know who to call when something goes wrong.

What We Have Done in Chengdu

When an import-export trading company in Chengdu’s Qingbaijiang District came to us, it had around 80 employees, its core business ran on Kingdee K3 and a self-developed order system, and it processed more than 500 orders a day. Their “backup plan” at the time consisted of manually copying a drive to an external hard disk before leaving work each day — a textbook single point of failure.

We did three things for them:

First, we deployed a Synology RS1221RP NAS in their server room with six 4TB enterprise drives in RAID6, running incremental backups of the core business database every six hours with a 30-day retention window. Second, we set up archival storage on Alibaba Cloud OSS connected to their order database for cross-region disaster recovery. Third, we placed a low-power small server at their Pidu branch, running a full synchronization once a week on Friday night — physically isolated, out of ransomware’s reach. Last year an employee accidentally deleted three months of order records, and recovery from the cloud took just fifteen minutes. On another occasion the power module in the local server burned out, and the Pidu machine took over the core business directly, keeping downtime under two hours. The owner said afterwards that the whole setup cost him less than a single outage.

Another client is a software company in Chengdu’s Tianfu New Area with an R&D team of more than 120 people, whose core assets are code and documentation. They had been through an incident before — their code repository server blue-screened and R&D stopped for half a day — so they take backup very seriously.

Our solution was highly targeted: full backups of the GitLab server every night, hourly incremental pushes during the day, and real-time reception at an offsite storage node. The code review platform database is backed up separately, and all R&D documents are archived to the cloud. In addition, we applied sTrust zero trust policies to their R&D network segment, blocking external USB drives on R&D computers to prevent attackers from penetrating through employee endpoints. Three months after implementation, their code recovery time objective is within 30 minutes, and the head of R&D finally sleeps well at night.

Core Deliverables of Enterprise Data Backup

1. Local NAS storage nodes: we recommend brands such as Synology, QNAP, or Huawei OceanStor based on company size and budget, configured with enterprise-grade drives under RAID protection. Local backup is the fastest recovery path, typically completing a full restore within 30 minutes.
2. Offsite disaster recovery nodes: beyond the local Chengdu data center, we deploy backup nodes in other cities in Sichuan or in partner data centers outside the province, so that a regional disaster (such as a data center power failure or flooding) does not wipe out all data at once.
3. Cloud disaster recovery archiving: integrated with Alibaba Cloud OSS or Tencent Cloud COS, with daily incremental uploads of core data and configurable retention (30 days / 90 days / one year). Cloud backups are inherently ransomware-resistant and out of the attacker’s reach.
4. Backup strategy configuration and drills: backup schedules are set according to the 3-2-1 principle, with a recovery drill every quarter and a drill report including remediation recommendations. A backup that has never been drilled is as good as no backup.
5. Ransomware protection integration: built on the sTrust zero trust solution, restricting the execution of suspicious processes and the connection of external devices, cutting off ransomware’s propagation paths inside the network. Backup is the last line of defense, but the best defense is keeping attackers out of the door.
6. Monitoring, alerting, and emergency response: backup jobs are monitored in real time, with automatic alerts on failure. We provide 7×8 technical support and on-site response within 2 hours in emergencies. Two backup health reports are issued each year.

Frequently Asked Questions

Q: What happens if a backup fails? Can you catch it for me?

A: Yes. Our monitoring system checks backup job status in real time and sends an alert to your administrator within 15 minutes of a failure, while logging the details for our engineers to diagnose. Common causes include insufficient storage space, network instability, or misconfigured backup software. Once we spot a problem, we reach out to you proactively — we do not wait for you to discover that data is gone before we respond.

Q: Can backups hold up against a ransomware attack?

A: That depends on how your backup architecture is designed. If the backup files sit on the same server with no offline copy, ransomware will most likely encrypt them too. Our recommended approach is offsite backup plus immutable snapshots, so backup data cannot be overwritten or deleted during the retention period. In addition, the sTrust zero trust solution blocks lateral ransomware spread at the endpoint level — a more proactive approach than backup alone.

Q: Is data in cloud backups secure? Could it leak?

A: Cloud transmission is encrypted with AES-256 throughout, and on the storage side the cloud service provider guarantees physical and network-level redundancy. As the service provider, Siwenlide retains the right to inspect data integrity and to perform recovery. You may also choose a privately deployed backup solution, keeping all data in your own data center. We support both models; it comes down to your requirements for data sovereignty.

Q: How long does recovery usually take?

A: Local NAS recovery is typically completed within 30 minutes. Cloud recovery depends on data volume and bandwidth, and usually takes 2-4 hours. For business-critical systems we recommend dual-server hot standby, which can keep failover within 15 minutes. Before signing the contract, we issue a detailed RPO/RTO assessment report, with explicit commitments for every metric.

Chengdu is home to a huge number of manufacturers, trading companies and technology firms, for whom data assets matter no less than a precision machine tool. With 14 years in IT operations and 1,000+ enterprise clients served, Siwenlide knows well how backup needs differ from industry to industry.
