For financial services firms, IT disaster recovery is not a compliance exercise—it is a critical control that underpins operational resilience, client trust, and regulatory standing.
Yet in practice, many organisations operate with disaster recovery plans that look robust on paper but fail under real-world conditions. For firms managing sensitive data, time-critical transactions, and regulatory obligations, that gap presents a material risk.
This article outlines what an effective IT disaster recovery approach should include, why many plans fail, and how financial services organisations can build a strategy that performs when it matters.
What is IT Disaster Recovery?
IT disaster recovery refers to the processes and technologies used to restore systems, data, and infrastructure following a disruption. This could include cyber attacks such as ransomware, infrastructure failure, human error, or outages from third-party providers.
For regulated firms, IT disaster recovery sits within a broader operational resilience framework. It is not just about restoring systems, but ensuring the business can continue delivering important services within defined impact tolerances, as outlined by the Financial Conduct Authority in its operational resilience guidance.
What Should an IT Disaster Recovery Plan Include?
An effective IT disaster recovery plan should focus on how the organisation actually recovers under pressure, rather than simply documenting intentions.
At its core, the plan must define how quickly systems are restored and how much data loss is acceptable. This is typically structured around Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs).
These objectives should be aligned to business priorities rather than technical assumptions.
It should also clearly identify critical systems and map them to business services, ensuring that recovery efforts are focused where they have the greatest operational impact. Alongside this, defined failover processes, roles and responsibilities, and a consistent approach to testing are essential.
For financial services firms, the plan must also align with regulatory expectations, ensuring that recovery capabilities are both practical and demonstrable.
Why Most IT Disaster Recovery Plans Fail
Despite having documentation in place, many organisations encounter failure at the point of execution. The causes are rarely technical alone—they are structural.
1. Plans Are Built for Compliance, Not Reality
Many firms develop IT disaster recovery plans to satisfy audit requirements rather than operational needs. Over time, these documents become outdated or too generic to be effective.
As environments evolve, systems change, and dependencies increase, the plan no longer reflects reality. When an incident occurs, teams are left working from assumptions rather than a reliable, up-to-date framework.
2. Overconfidence in Backups
Backups are often treated as the foundation of IT disaster recovery, but they are only one component of a broader strategy.
In many cases, organisations discover during an incident that backups are not as recent as expected, recovery processes are slower than required, or data integrity has not been fully validated.
Guidance from the National Cyber Security Centre highlights the importance of secure, tested backups as part of a wider resilience strategy.
Without a defined and tested recovery process, backups alone do not ensure continuity.
3. Lack of Regular Testing
A disaster recovery plan that is not regularly tested cannot be relied upon in a live scenario. Many organisations carry out limited testing, often focusing on isolated systems rather than the full recovery process.
Effective testing should replicate realistic scenarios, including cyber incidents and full system outages.
It should also involve both IT and operational stakeholders, ensuring that recovery procedures are understood and aligned with business priorities.
4. Misalignment With Business Priorities
IT disaster recovery is often approached from a technical perspective, which can lead to a disconnect between system recovery and business impact.
This can result in non-critical systems being restored ahead of those that support revenue generation or client services. To be effective, recovery priorities must be driven by business requirements, ensuring that the most important services are restored first.
5. Third-Party Risk Is Not Fully Considered
Financial services firms depend heavily on third-party platforms and providers. However, these dependencies are not always fully reflected in IT disaster recovery planning.
- Vendor recovery capabilities may not be independently verified
- Service level agreements may not align with internal recovery objectives
- Interdependencies between systems can be unclear
This creates a situation where an external failure can quickly become an internal operational issue, with limited control over resolution.
How to Build an IT Disaster Recovery Strategy That Works
To move from documentation to operational resilience, IT disaster recovery must be treated as a live capability rather than a static plan.
1. Start With Business Impact, Not Technology
An effective approach begins by identifying critical business services and understanding the impact of disruption. This includes defining acceptable downtime and assessing regulatory and client implications.
Systems can then be mapped to these services, ensuring recovery priorities reflect real business risk rather than technical preference.
2. Define Clear, Achievable Recovery Objectives
Recovery objectives must be realistic and aligned with operational needs. Setting overly ambitious targets without the supporting infrastructure often leads to failure in practice.
Organisations should ensure that both RTOs and RPOs are achievable and validated through testing.
3. Implement Layered Recovery Strategies
A resilient IT disaster recovery strategy should incorporate multiple layers of protection rather than relying on a single method.
This typically includes:
- Secure, immutable backups to protect against data loss or corruption
- Cloud-based failover environments to enable rapid recovery
- Segregated infrastructure to limit the spread of incidents
This layered approach reduces risk and improves overall recovery capability.
4. Test Against Realistic Scenarios
Testing should go beyond basic validation and reflect real-world disruption. This includes simulating ransomware attacks, infrastructure failure, and third-party outages.
Involving both technical and business stakeholders ensures that recovery processes are practical, effective, and aligned with operational requirements.
5. Continuously Review and Update
IT environments are constantly evolving, and disaster recovery strategies must evolve with them. New systems, integrations, and regulatory expectations all impact recovery planning.
A structured review cycle ensures the plan remains relevant, accurate, and capable of supporting the organisation during an incident.
IT Disaster Recovery for Financial Services Firms
For organisations in investment management, private equity, and financial advisory, IT disaster recovery is closely tied to regulatory expectations around operational resilience.
Firms must demonstrate that they can continue delivering important business services during disruption, not just recover systems.
This requires clear identification of those services, defined impact tolerances, and the ability to operate within them under stress.
For firms in the 20–200 employee range, the challenge is delivering this level of resilience without the scale of larger enterprises. This often requires a structured approach that combines internal oversight with external expertise, ensuring both compliance and operational effectiveness.
From Plan to Confidence
IT disaster recovery should not exist purely as documentation—it should provide confidence that your organisation can operate through disruption.
For senior stakeholders, the focus should be on proven recovery capability, alignment with business risk, and clear governance.
This includes regular testing, defined responsibilities, and a consistent approach to improvement.
Organisations that take this approach are better positioned to protect client trust, meet regulatory expectations, and maintain continuity in the face of disruption.
Next Steps
If your current IT disaster recovery plan has not been tested against realistic scenarios, there is a risk it will not perform when required.
A structured review can help identify gaps in recovery capability, highlight misalignment with business priorities, and provide a clear path to strengthening resilience.
For mid-size financial services firms, this is an essential step in building a dependable, audit-ready IT disaster recovery strategy.
