What is Business Continuity and Disaster Recovery?
Business Continuity and Disaster Recovery (BCDR) is the combined discipline of keeping a company operating during a serious disruption and restoring its technology afterward. Business continuity covers the operational side: how staff keep working and how customers are served when the office or the network is unavailable, and who makes decisions while it is. Disaster recovery covers the technical side: how servers, data, network gear, and cloud services are restored, in what order, and how quickly. The two are written together because neither works alone.
A BCDR plan starts with a business impact analysis that lists each process, the systems it depends on, how long it can be interrupted, and what the interruption would cost. From that come two figures for every system: a recovery time objective, which sets how fast it must be back, and a recovery point objective, which sets how much data may be lost. The plan then describes the backup and replication methods that meet those figures, the alternate ways of working while systems are down (paper forms, a phone tree, laptops on home connections, a forwarded main number), the order in which systems are restored, and the names and phone numbers of the people responsible. It also covers events that are not cyberattacks: a burst pipe above the server closet, a regional power failure, a hurricane, or a vendor outage that takes a cloud service offline.
For a small or mid-sized business, the plan does not need to be long, but it does need to be tested. A tabletop exercise, where the owner and a few staff walk through a scenario for an hour, finds most of the gaps: the one person who knows the backup password, or the customer list that only exists on a laptop. Insurers and larger customers now ask whether such a plan exists and when it was last exercised.
NetSys includes disaster recovery planning in every managed agreement instead of selling it as a separate project, and the plan is written with the business continuity side in view, so the client knows how to operate while systems are restored. Over three years NetSys has handled more than 30 ransomware incidents with full recovery in every case, and the clients who had a disaster recovery plan in place were back within 24 hours.
Why it matters for a small business
A disruption hurts a business twice: once when the systems fail and again for every hour the company cannot serve its customers. BCDR planning decides in advance how you will take orders and pay people while the technology is being rebuilt, and it makes the rebuild itself a checklist rather than an improvisation. For a small company the exercise is a few hours of the owner's time. The payoff is a known recovery time and a known amount of data at risk, plus written answers for the insurer or a large customer when they ask how prepared you are.
Business Continuity and Disaster Recovery (BCDR): FAQs
What is the difference between business continuity and disaster recovery?
Business continuity is about keeping the company operating during a disruption: alternate ways to serve customers and reach staff while normal systems are unavailable, and who decides what in the meantime. Disaster recovery is about restoring the technology itself, meaning servers, data, network, and cloud services, within the time the business can tolerate. Disaster recovery is one component of business continuity. A company can restore every server perfectly and still fail its customers if nobody planned how to work during the two days that took.
Does a small business need a BCDR plan?
Yes, and it can be short. Any company that depends on email or a line-of-business application to earn money has something to lose when those stop, and most insurers and larger customers now ask whether a written plan exists. A practical small-business plan fits in a few pages: the systems that matter, the recovery targets for each, where the backups are and who can restore them, how staff will work in the meantime, and the phone numbers to call. Test it once a year.
How often should a business continuity plan be tested?
At least once a year, and again whenever something important changes, such as a new server or a change in who holds the administrator credentials. A test does not have to be a full failover. A tabletop walk-through with the owner and key staff takes an hour and finds the gaps that matter most. A technical restore test of the most important system should happen more often than the full exercise, because backups fail quietly.
