A Guide to Planning for Disaster Recovery

Could your organisation quickly and safely recover data and operations in the event of a system failure? There’s no mistaking that most businesses would be in pretty deep trouble should their technology fail. Whether the interruption is caused by a cyber-attack, hardware failure, or even a natural disaster, digital infrastructure is integral to almost every aspect of almost any organisations’ operations.  

However, with the rise of technology, the risk of these type of disruptions has also increased; cyber threats, political unease, and even simple human error can all play a part in causing unexpected disturbances (or even monumental disasters) when it comes to technology – and this is where backup and recovery planning comes into play.

What is disaster recovery?

Disaster Recovery (DR) is a set of policies, tools, and procedures designed to enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster.

Effective DR planning, therefore, ensures that an organisation can quickly resume critical functions, minimising downtime and data loss, while also mitigating any damage along the way, e.g., through restoring customer trust or preserving data integrity.

Remember, disaster recovery isn’t just about backing up data – it’s about ensuring that the entire infrastructure can be restored. To this end, plans typically include:

• Backup strategies: including how data is backed up, where it’s stored, and how often backups are made. On this note, customers of Microsoft might also be interested in learning more about the Microsoft shared responsibility model which states that, while Microsoft is responsible for securing underlying infrastructure, it is not responsible for data loss prevention – that’s on you.
• Maximum tolerable outage (MTO): this means thinking ahead to the worst possible outcome and deciding the maximum time allowed for an outage before the business, essentially, becomes unviable. Whilst this might feel defeatist, knowing the MTO actually helps in setting realistic recovery objectives (see below) and keeps recovery time planning on track.
• Recovery time objectives (RTO): pointing to the amount of acceptable downtime for critical systems or applications. Usually decided via a Business Impact Analysis (BIA), RTOs involve a combination of determining factors including the potential impact of system downtime on business operations, financial losses, customer satisfaction, regulatory compliance, reputational damage, and the feasibility of achieving a specific recovery time.
• Recovery point objectives (RPO): this is an agreed-upon acceptable amount of data loss, typically measured in time (e.g., three hours of data). RPOs are usually decided in advance by evaluating the maximum amount of data loss a business is willing to tolerate in the event of a system failure. This decision takes into consideration multiple factors such as business impact, data sensitivity, and the cost of recovery.
• Communication strategies: denoting how employees, customers, and stakeholders will be kept informed in the event of a disaster. Your organisation may wish to set-up a crisis communication team to coordinate comms during an emergency, ensuring all messages are consistent and accurate. Effective communication during system failure helps minimise confusion and frustration, returning vital trust and promoting a sense of teamwork.
• Testing procedures: disaster recovery plans should be tested regularly to ensure they are effective and up to date. The frequency of testing can vary depending on the organisation’s size, industry, and specific needs, but most organisations conduct a comprehensive test of their disaster recovery plan at least once a year.

Why is disaster recovery so important?

It’s easy to fall into the trap of thinking that disaster recovery is only necessary for huge corporations with more on the line, but this is false. No company, regardless of size or type, is immune to the impact of disruptions.

Moreover (and not to sound cliché), but the world today is inextricably interconnected by technology. This means that the ripple effect of digital disasters has the potential to extend far beyond their own immediate impact on the organisation in question. Remember, customers, suppliers, and partners all rely on the stability and continuity of your operations. A well-prepared disaster recovery plan ensures that you can maintain trust and reliability, even in the face of unexpected challenges, this includes:

Minimising downtime

The longer your systems are down, the more it costs. Downtime can result in lost revenue, decreased productivity, and damaged customer trust. Having a solid disaster recovery plan in place allows your organisation to get back up and running faster, minimising the financial and operational impact.

Protecting customer trust

Customers expect businesses to be reliable – after all, they’re usually parting with their cash for your services. If your organisation experiences prolonged downtime or a data breach, you risk losing your customers’ trust. A disaster recovery plan helps maintain this trust by ensuring that you can respond quickly to such events and continue delivering services with minimal interruption.

Compliance and legal obligations

For many industries, disaster recovery is not just a best practice—it’s a requirement. Regulations such as GDPR and HIPAA mandate that businesses take appropriate measures to protect customer data and ensure business continuity. Failing to implement disaster recovery procedures can result in hefty fines and legal repercussions.

Data protection

One of the main objectives of any disaster recovery plan is to protect critical data, ensuring that it can be recovered. This involves implementing measures to ensure that, in the event of a disaster, essential information remains intact and can be restored promptly.

Building a disaster recovery plan

While I always recommend consulting the professionals when it comes to something as important as this (to ensure no critical steps are missed and that products are monitored for vulnerabilities, etc.), there are common steps and best practices to follow when creating your disaster recovery plan:

Conduct a business impact analysis (BIA)

To begin with, a BIA helps identify critical business functions and the potential impact of any disruption to them. This analysis allows organisations to prioritise resources and recovery efforts with more accuracy.

Develop a comprehensive business continuity plan (BCP)

A BCP outlines procedures for maintaining essential functions during and after a disaster. It should include detailed steps for responding to various types of disruptions.

Implement redundant systems and infrastructure

Investing in redundant systems, such as backup servers and network infrastructure, ensures that critical operations can continue even if primary systems fail, minimising downtime and data loss.

Regularly test and update

Regular testing of the BCP through drills and simulations helps identify weaknesses and areas for improvement. Updating the plan to reflect changes in the business environment and emerging threats also ensures its ongoing effectiveness

Train employees

Providing training and awareness programs for employees ensures they understand their roles and responsibilities in the event of a disaster. Remember, well-trained staff can respond more effectively, reducing the impact of a disruption.

Establish communication protocols

As mentioned, effective communication is crucial during a disaster. Establishing clear communication protocols ensures that all stakeholders, including employees, customers, and partners, are informed and updated throughout the recovery process.

Utilise cloud-based solutions

Cloud-based solutions offer scalable and flexible options for data backup and recovery. They provide offsite storage, reducing the risk of data loss due to physical disasters, and enable rapid restoration of services.

Implement cyber security measures

Integrating cyber security measures into your BCP helps protect against threats like malware and ransomware and cloud-based solutions such as Entra ID for identity management ensures that only authorised users can access critical systems and data. During a disaster, maintaining this access is crucial for business continuity.

Monitor and review 

Continuously monitoring and reviewing continuity measures ensures they remain effective. This includes tracking performance metrics and making necessary adjustments based on recent experiences and emerging threats.

Final word

Unfortunately, disaster recovery planning is no longer optional. The potential disruptions caused by cyber-attacks, natural disasters, and other unforeseen events are simply too great to ignore.

However, by working in tandem with a trusted service provider to implement a robust disaster recovery strategy and leveraging services such as M365 backup and recovery, businesses can ensure that their operations remain secure and that data and, most importantly, people are protected.
