The Essential Guide to Business Data Backup

In recent Singapore news, a ransomware attack on a third-party service provider exposed customer data, including personal details and financial information, for thousands of individuals. While core systems remained secure, the incident underscores that third-party weaknesses and inadequate backup or recovery plans can quickly escalate into a reputational and financial crisis.

1. The High Cost of Data Loss

According to Singapore’s PDPC Data Breach Landscape 2023–24, reported large-scale data breaches rose by 41% in one year, with ransomware accounting for 62% of enforcement cases.

Meanwhile, the IBM Cost of a Data Breach Report 2024 (via ComputerWeekly) revealed that the average cost of a data breach in the ASEAN region is S$4.34 million, factoring in lost business, recovery expenses, regulatory fines, and reputational repair.

But the impact isn’t just financial. Downtime, missed contracts, and loss of customer trust often leave long-term scars. As highlighted in Nucleo’s article, Why Data Backup is Important for Businesses, SMEs are especially vulnerable—every corrupted record or deleted file can directly disrupt continuity.

2. Different Types of Backup Solutions

Choosing the right backup method depends on your business operations, compliance requirements, and budget.

Approach	What It Is	Pros	Cons
Local / On-Premise Backups	Data stored in physical devices within your office or data centre	Fast recovery; complete control; good for large files	Vulnerable to theft, hardware failure, or disasters like fire/flood
Cloud-Based Backups	Data stored securely in cloud infrastructure	Off-site safety; scalability; automatic redundancy	Ongoing subscription cost; internet dependency; compliance considerations
Hybrid Approach	Combination of local and cloud storage	Combines speed + safety; redundancy across platforms	Slightly more complex to manage; potentially higher cost

A simple but powerful rule to follow is the 3-2-1 Backup Rule: keep three copies of your data, on two different media, with at least one stored offsite. Nucleo explains this in detail in Master the 3-2-1 Backup Rule: Essential Cybersecurity Tips You Need to Know.

3. Creating and Testing a Reliable Backup Strategy

Having a backup is only half the battle—you need to ensure it can be recovered when disaster strikes.

Backup & Recovery Plan Checklist:

Inventory all data sources – from servers and laptops to SaaS apps and cloud storage.
Set frequency & retention policies – daily, weekly, or according to PDPA requirements.
Ensure redundancy & offsite copies – avoid relying on a single location or medium.
Encrypt backups & secure access – protect against unauthorised breaches.
Assign clear responsibilities – specify who manages, tests, and restores backups.
Test regularly – run restore drills to validate recovery time and data integrity.
Review & update – revise plans after IT changes or annually.

Many businesses assume cloud services alone are enough, but as Nucleo notes in Shared Responsibility in Cloud Services, providers secure infrastructure, while the responsibility for safeguarding data remains with the business itself.
