The Infrastructure Mistakes Almost Everyone Makes First Time Round
Business continuity and disaster recovery are often mentioned together, and for good reason. Both are designed to help organisations continue operating when something goes wrong.
Yet despite being closely connected, they aren’t the same thing at all.
After working in the infrastructure space for over twenty years, one of the questions I’m probably asked more than any other is where the line sits between business continuity and disaster recovery. Many organisations use the terms interchangeably, whilst others invest heavily in one and overlook the other altogether.
The reality is that both are essential.
Business continuity focuses on keeping your organisation operating during disruption, whilst disaster recovery focuses on restoring the technology that enables those operations.
One supports the business, the other restores the systems, and together they form the foundation of organisational resilience.
Understanding the difference helps organisations make better decisions, invest in the right areas and build a more effective response when disruption inevitably occurs.
At first glance, it’s easy to understand why the two concepts become blurred. Both deal with disruption, both involve planning ahead and both aim to minimise downtime.
In practice, however, they answer different questions.
Business continuity asks:
“How do we keep operating?”
Whilst disaster recovery asks:
“How do we restore the technology that allows us to operate?”
They work towards the same objective, but they’re both approach it from different directions.
Whether the disruption is caused by a cyber-attack, hardware failure, flooding, human error or a power outage, every organisation wants the same outcome.
They want to continue serving customers, supporting employees and protecting critical operations with as little interruption as possible. That shared objective is why business continuity and disaster recovery are often planned together.
Business continuity looks at the organisation as a whole. Disaster recovery focuses on restoring the systems that support that organisation. Neither is more important than the other. They’re simply responsible for different parts of the same challenge.
Business continuity is the wider strategy for ensuring an organisation can continue delivering its most important services during disruption. Technology plays a role, but it’s only one piece of the puzzle. A business continuity plan considers people, communication, suppliers, locations, critical processes and operational priorities alongside IT.
If an office becomes inaccessible, can staff work elsewhere? If a supplier fails, is there an alternative? If customers can’t access normal services, how will they be kept informed?
These are business continuity questions.
The objective isn’t necessarily to return to normal immediately. It’s to maintain essential operations whilst the organisation responds to the situation.
Technology underpins almost every modern organisation, but it isn’t the only dependency.
Buildings, third-party suppliers, utilities, key personnel and documented processes all contribute to whether an organisation can continue operating. Business continuity brings all of these elements together into a coordinated response.
Disaster recovery sits within the wider business continuity strategy and focuses specifically on restoring technology after disruption. That includes applications, servers, cloud services, networks, data, identity platforms and the infrastructure that supports them.
The objective is simple. Restore systems safely, efficiently and in a predictable way.
When systems become unavailable, disaster recovery determines how they’re recovered.
That might involve restoring backups, failing over to secondary environments, rebuilding infrastructure or recovering cloud services.
The exact approach depends on the organisation, but the goal remains the same.
Reduce downtime whilst protecting data and maintaining service availability.
Traditional disaster recovery often relied on lengthy documentation and manual recovery processes. Today’s environments look very different.
Cloud platforms such as Microsoft Azure, automation and Infrastructure as Code allow organisations to recover systems faster and with greater consistency than was previously possible.
Technologies such as Puppet, Ansible and Chef can automate configuration, whilst modern cloud services help reduce the manual effort involved in rebuilding infrastructure after an incident.
Disaster recovery has become far more than simply restoring servers. It’s about designing resilient platforms that are prepared for failure from the outset.
One of the biggest misconceptions I still encounter is that organisations can prioritise one without investing in the other.
In reality, doing so creates far too much risk, all of it unnecessary.
Imagine an organisation that has an excellent business continuity plan. Everyone understands their responsibilities. Communication plans are in place. Alternative working arrangements have been agreed.
But the organisation’s core systems remain unavailable for days because there’s no effective disaster recovery capability.
The business knows what it needs to do, but the technology can’t support it.
Now imagine the opposite.
Infrastructure is recovered quickly, yet nobody knows which services should be restored first, how customers should be updated or how staff should adapt whilst systems are unavailable.
Technology alone doesn’t keep an organisation operating.
Both disciplines depend on one another.
The strongest organisations don’t treat business continuity and disaster recovery as separate projects owned by different teams.
They recognise that technology and business operations have become increasingly connected.
Infrastructure decisions influence operational resilience, whilst business priorities shape how recovery strategies are designed. That means planning both together creates a far more resilient organisation than addressing either in isolation.
Consider a ransomware attack affecting a customer relationship management system.
From a business continuity perspective, the focus is on maintaining customer service.
Both responses happen alongside each other. Neither succeeds without the other.
Business continuity and disaster recovery are closely connected, but they shouldn’t be confused.
Business continuity keeps the organisation functioning during disruption.
Disaster recovery restores the technology that allows it to function.
As organisations continue adopting cloud platforms, automation and modern infrastructure, the relationship between the two has become even stronger. Technology can no longer be viewed in isolation from the business it supports.
In my experience, the organisations that recover most effectively are those that plan both together. They understand that resilience isn’t created by documentation alone or by technology alone. It’s created when business strategy and technical recovery are designed to support one another from the very beginning.

What Is IAC (Infrastructure-As-Code)?
A business continuity plan should identify critical business processes, key personnel, communication procedures, alternative working arrangements, supplier dependencies and the actions needed to maintain essential services during disruption.
Business continuity plans should be reviewed at least annually, or whenever there are significant organisational changes such as new systems, office locations, acquisitions or changes to critical business processes.
Whilst there is no single law requiring every organisation to have a business continuity plan, many industries are subject to regulatory or contractual requirements that expect organisations to demonstrate resilience and continuity planning.
Business continuity is typically led by senior management because it affects the entire organisation, whilst disaster recovery is often managed by the IT or infrastructure team. The most successful organisations ensure both teams work closely together.
Modern business continuity planning must consider cyber threats such as ransomware and data breaches alongside traditional risks like hardware failures and natural disasters. Response plans should cover both operational and technical recovery.

Yes. Cloud platforms such as Microsoft Azure can improve resilience through features like geographic redundancy, automated failover, scalable infrastructure and cloud-based backups. However, organisations still need appropriate planning, testing and governance to make effective use of these capabilities.
Testing can range from simple tabletop exercises and scenario discussions through to full operational simulations involving staff, suppliers and IT teams. Regular testing helps identify weaknesses before a real incident occurs and ensures plans remain relevant as the organisation evolves.
