What is an IT disaster recovery plan?
Most business owners, if asked whether they have a disaster recovery plan, will say something like "yes, we back everything up." And while backups are a critical part of disaster recovery, they are not the whole plan. Backups tell you where your data is. A disaster recovery plan tells you what to do when something goes seriously wrong, and who does it, in what order, and how quickly.
According to UK government data, only around a third of businesses have a formal incident response plan. That means the majority are effectively improvising when a crisis hits, which is exactly when improvisation is most expensive.
What is an IT disaster recovery plan?
An IT disaster recovery plan (often abbreviated to DR plan or DRP) is a documented set of procedures that tells your business how to respond to, and recover from, a significant IT incident. The incident could be anything from a ransomware attack to a server failure, a flooded office, a key member of staff being unavailable, or a major software failure.
The plan is not a technical document for IT specialists. Its purpose is to give everyone involved, from senior management down to individual staff, clarity about what to do when something goes wrong, so that the response is structured rather than panicked.
A disaster recovery plan is related to, but distinct from, a business continuity plan. Business continuity covers how the whole organisation keeps operating during a disruption. Disaster recovery focuses specifically on restoring IT systems and data.
What should a DR plan cover?
A practical disaster recovery plan for a small or medium sized business does not need to be a hundred page document. It does need to cover these core areas:
A list of your critical systems Every application, piece of software, and data source that your business could not function without. For most SMEs this includes email, file storage, accounting software, and any customer or operational databases. The list needs to include where each system is hosted, who manages it, and what the dependencies between systems are.
Recovery time and recovery point objectives Recovery Time Objective (RTO) is how quickly a system needs to be restored before the impact becomes unacceptable. Recovery Point Objective (RPO) is how much data loss you can tolerate, in other words, how old can the most recent backup be? These are commercial decisions as much as technical ones, and they determine how sophisticated your backup and recovery setup needs to be.
Contact lists Who to call when something goes wrong. This should include your IT provider's emergency contact details, your cyber insurer, relevant software vendors, and key internal staff. Critically, this list needs to be accessible when systems are down, which means a printed copy kept somewhere accessible, not just a document saved on the server that has just failed.
Response procedures for likely scenarios A ransomware attack looks different to a server failure, which looks different to a flood. Your plan should include specific steps for the most likely scenarios your business might face: what to isolate, what to shut down, what to restore first, and who makes those decisions.
A backup and restore process Where are your backups? How do you restore from them? Who has access? How long does a full restore take? These questions need answers before you need them, not during the crisis itself.
Communication guidance Who needs to be told what has happened, in what order? Staff, clients, suppliers, insurers, regulators: each may need different information at different stages of an incident. Knowing this in advance prevents both over-communication that creates panic and under-communication that creates legal or regulatory problems.
What are realistic recovery targets for a small business?
This depends on your business, but here are some practical reference points.
For most small businesses, an RTO of four to eight hours is achievable with a well configured cloud setup and a tested restore process. That means being substantially operational within a working day of a serious incident. An RTO of 24 to 48 hours is more typical for businesses that rely on on site infrastructure without a cloud failover option.
For RPO, the age of the most recent backup you could restore from, daily backups are the minimum sensible standard for most SMEs. For businesses where losing a full day's work would be particularly damaging, more frequent backups (every few hours, or continuous replication) are worth considering.
The test that most businesses skip
The single most common weakness in disaster recovery planning is that the plan has never been tested. A backup that has never been restored from is not a reliable backup. A plan that has never been rehearsed is not a reliable plan.
Testing does not have to be dramatic. A tabletop exercise, sitting key people around a table and walking through what would happen if a particular scenario occurred, takes an hour or two and surfaces gaps that would otherwise only become visible during an actual incident. Testing a backup restore from a recent backup takes a few hours and confirms that the process actually works.
Both of these things should happen at least annually, and whenever there is a significant change to your IT setup.
Does your business have a plan?
If the honest answer is no, or "we have something but it has never been properly written down or tested", you are in good company, but that is worth changing.
