DR vs Business Continuity
Defining Disaster Recovery and Business Continuity
Disaster recovery vs business continuity comes down to scope. Disaster recovery restores an organisation's IT systems and data after a disruption, such as a failed server, lost data or a cyberattack. Business continuity is the wider planning effort that keeps essential operations running during and after a disruption, covering people, premises, suppliers and communication.
The two overlap, but they answer different questions. Disaster recovery asks how the systems come back. Business continuity asks how the business keeps serving customers while they are down, and what it does about payments, deliveries and reputation in the meantime.
How the Two Plans Fit Together
Disaster recovery is usually one part of a business continuity plan. The continuity plan sets priorities: which services matter most, how long each can be unavailable and what the business does in the meantime. The disaster recovery plan provides the technical route to bring those services back.
For a website, the disaster recovery plan restores the shop from backup, while the continuity plan decides whether to show a holding page, accept orders by email or pause marketing until the site is back. Each plan needs the other to be useful. The technical side is covered in more detail in a disaster recovery plan for a website.
Why Recovery Targets Connect the Two
Recovery targets link the two plans. The data loss and downtime a business can tolerate shape the backup frequency and the restore process. If a business cannot lose a day of orders, the continuity plan demands a backup approach that supports that, and the disaster recovery plan must deliver it. The measures for this are explained in RPO vs RTO.
The reverse also holds. If the technical team finds that a restore takes longer than the business expects, that finding should flow back into the continuity plan. The business may need a temporary alternative, such as a simpler sales page or a manual order process, to cover the gap.
An Online Shop During an Outage
A clothing shop goes offline because its hosting account is suspended in error. The disaster recovery plan calls for restoring the site on a new host from the latest backup, which takes most of a day. Meanwhile the continuity plan directs staff to post a notice on social media, take orders by email from existing customers and tell the payment provider and couriers what is happening.
When the site returns, the team checks the orders taken by email against the restored data before resuming normal operations.
Frequently asked questions
Do small websites need business continuity planning?
Most small sites do not need a formal document, but they benefit from the same questions. What happens to sales if the site is down for a day? Who tells customers? Which supplier or service must be contacted first? Answering these in a short note gives a small business a basic continuity plan without the overhead of a large organisation.
Which plan should I write first?
For most website owners, a disaster recovery plan comes first, because the technical restore is what every other response depends on. Once it exists, a continuity view can be added to decide how the business operates during the gap. Both are worth writing, and each makes the other easier to maintain.
