The Importance of Data Backup in New Zealand

New Zealand businesses face unique risks—earthquakes, floods, and other natural disasters can strike without warning. Add cyber threats like ransomware, and the need for robust data backup and disaster recovery becomes crystal clear. Can your business survive if you lost all your data today?

Common Causes of Data Loss

  • Hardware Failure: Hard drives fail, servers crash, and equipment malfunctions
  • Human Error: Accidental deletion, overwriting files, or configuration mistakes
  • Ransomware: Malicious software that encrypts your data and demands payment
  • Natural Disasters: Earthquakes, floods, fires, or storms damaging physical infrastructure
  • Theft: Stolen devices containing sensitive business data
  • Software Corruption: Bugs, conflicts, or failed updates corrupting data

The 3-2-1 Backup Rule

This industry-standard approach provides comprehensive protection:

  • 3 Copies: Maintain three copies of your data—the original plus two backups
  • 2 Different Media: Store backups on two different types of media (e.g., disk and cloud)
  • 1 Off-Site: Keep at least one backup copy off-site or in the cloud

Backup Strategies for NZ Businesses

Cloud Backup

Cloud-based backup services automatically copy your data to secure data centres. Benefits include:

  • Automatic, scheduled backups requiring minimal management
  • Geographic redundancy—data stored in multiple locations
  • Easy scalability as your data grows
  • Access from anywhere for disaster recovery

NZ Consideration: Choose providers with data centres in New Zealand or Australia to maintain data sovereignty and reduce latency.

Local Backup

On-site backups using external hard drives or network-attached storage (NAS) offer fast recovery times for routine restores. However, they're vulnerable to the same physical threats as your primary systems.

Hybrid Approach

Many businesses combine local and cloud backups—local for quick daily restores, cloud for disaster recovery and long-term retention.

Disaster Recovery Planning

A backup is only useful if you can restore from it when needed. A comprehensive disaster recovery plan includes:

1. Recovery Time Objective (RTO)

How quickly must you restore operations? A retailer during the holiday season might need systems back within hours, while a consulting firm might tolerate a day or two.

2. Recovery Point Objective (RPO)

How much data can you afford to lose? This determines backup frequency. If you can only accept one hour of lost data, you need more frequent backups than if a day's loss is acceptable.

3. Testing and Documentation

Regularly test your restore process. Document step-by-step procedures so anyone on the team can execute recovery if needed. Many businesses discover their backups don't work only when disaster strikes.

4. Communication Plan

Define who to contact, how to inform customers and staff, and how to coordinate recovery efforts during a crisis.

What to Back Up

Ensure you're capturing all critical data:

  • Customer and financial databases
  • Email and communications
  • Documents, contracts, and intellectual property
  • Application configurations and customisations
  • Operating system settings and application software
  • Website content and e-commerce data

Retention Policies

Balance storage costs with compliance and business needs:

  • Daily backups: Retain for 30 days for recent file recovery
  • Weekly backups: Retain for 3 months for medium-term needs
  • Monthly backups: Retain for 1-7 years for compliance and long-term reference

Compliance and Legal Requirements

New Zealand businesses must comply with the Privacy Act 2020, which includes requirements for data protection and retention. Industry-specific regulations may impose additional obligations. Ensure your backup strategy meets these requirements.

Ransomware Considerations

Ransomware can encrypt backups too if they're accessible to infected systems. Protect against this by:

  • Using immutable backups that can't be modified or deleted
  • Storing backups offline or air-gapped from your network
  • Implementing strict access controls for backup systems
  • Maintaining multiple versions so you can restore from before infection

Costs and ROI

Backup and disaster recovery isn't free, but it's far cheaper than losing your business. Consider the cost of downtime—lost revenue, damaged reputation, and potentially permanent closure. For most businesses, comprehensive backup is a bargain.

Managed Backup Services

Many NZ businesses outsource backup management to ensure it's done properly without burdening internal IT staff. Managed services providers monitor backups, perform test restores, and manage retention policies—giving you peace of mind.
