Disaster Recovery vs Business Continuity: What's the Difference?
Disaster Recovery vs Business Continuity: What's the Difference?
Disaster recovery vs business continuity comes down to two jobs. Disaster recovery restores your IT systems and data after a serious incident. Business continuity keeps the organisation running in the meantime, including people, premises, suppliers and how you talk to customers.
You need both. They should point at each other, be tested, and stay short enough to use. A backup on its own is not a continuity plan, and moving to the cloud does not remove the need for either.
What disaster recovery covers
Disaster recovery is the IT side of an incident. The aim is to restore systems and data, in a sensible order, within a timescale the business can live with.
A useful disaster recovery plan usually answers four questions:
- What do we need to bring back first? Email, files, accounts software and line-of-business systems are often at the top of that list.
- How long can we manage without each one?
- How much data can we afford to lose, measured in time? That decision drives how often you back up.
- Who does the restore, and where are the backups?
It also has to deal with the causes you are most likely to face. In the businesses we support, that is usually ransomware or another cyber attack, a server or drive failing, accidental deletion, a power cut or flood, or a cloud service or internet connection going down. The plan should say how you restore from those events, not only from a tidy practice run.
Backups sit at the centre of this. A copy in one place is not enough if the same incident can reach it. You also need to know that Microsoft 365, or any other cloud service, will not necessarily restore deleted or encrypted data for you. Keeping the service online is not the same as being able to get your mail and files back.
What business continuity covers
Business continuity looks at the whole organisation. IT is part of it, but so are people, premises, suppliers and the way you talk to customers.
A continuity plan is there for the first hours and days of a disruption, when the question is "how do we keep trading?" rather than "how do we rebuild the server?" It might cover:
- Where staff will work if the office cannot be used
- How you will take calls and payments if the usual systems are down
- Which suppliers you depend on, and what you will do if one of them cannot deliver
- Who speaks to staff, customers and insurers, and how, if email is unavailable
- Local risks that matter to you, such as flooding, a long power cut, or a problem with the building
On our business continuity page we describe this as identifying the threats worth preparing for, setting out the first steps, and keeping the plan current. A short document that people can actually follow is more use than a long one that is out of date.
How the two plans work together
Business continuity is the wider plan, and disaster recovery is the IT chapter inside it. You need both, and they should point at each other.
Continuity decisions shape the IT work. If the business cannot go a morning without email, the recovery plan has to meet that timescale. If staff can work from home on cloud services for a few days, you may be able to restore some office systems more slowly. Those are commercial choices, not technical ones, and they should be written down before an incident, not made in a panic.
Recovery work also feeds the continuity plan. If a restore will take a day, the continuity plan has to say how the team will operate during that day. If your files live in Microsoft 365, the continuity plan should include how you will handle a tenant-level problem, and the recovery plan should include extra protection for that data. Our page on protecting your cloud data covers more of that ground.
The two plans should also be tested together from time to time. A successful file restore is only half the picture if nobody knows how to tell customers what is going on.
Common mix-ups
The most frequent mix-up is treating a backup product as a continuity plan. A backup is a tool. It does not tell you who is in charge, how you will communicate, or what the business will do while systems are down.
Another is assuming that moving to the cloud removes the need for either plan. It changes the work, because you may no longer be rebuilding a server in the office, but you still need a way to restore data, a way to work if the internet is down, and a named person to make decisions.
People also confuse the two acronyms. A disaster recovery plan (DRP) is the IT restore plan. A business continuity plan (BCP) is the wider organisational plan. If a contract, insurer or auditor asks for one, check which they mean, because handing over the wrong document wastes time.
What this means for a small or medium sized business
Two short, tested documents that match how you actually work will do more than a thick binder.
For most of the organisations we support, a sensible starting point is:
- A one-page or few-page continuity plan covering people, premises, communication and the first day of a disruption
- A disaster recovery plan that lists critical systems, backup arrangements, restore order and named contacts
- An agreed review, at least once a year or when you change systems, suppliers or office arrangements
Insurers, larger customers and many public sector contracts now expect to see this, often alongside Cyber Essentials. Smaller teams usually have less spare capacity when systems are down, so the plans matter at least as much as they do in a larger company.
How Bluespires can help
Bluespires has been supporting businesses since 2010. Today we look after more than 170 businesses, including over 40 charities, from our base in Witney.
We can help you put backups and disaster recovery in place, and write and maintain the wider continuity plan. That includes looking at where your data is held, how quickly each system needs to come back, and whether your current backups would actually restore.
If you are not sure whether you have a recovery plan, a continuity plan, or just a backup you have never tested, book a free consultation or call 01865 959160.
