2019: IT Disaster Recovery explained

The terms business continuity, IT resilience, Backup and Disaster Recovery can often be discussed but do we really understand their meaning? A business can often be left unsure of what to look for to adequately protect their business. This means that often the decision not to protect your business at all can be the simplest one.

Here we clarify the meaning of the terms as simply as we can. Each of these terms relates to IT systems. All act however in slightly different measures to keep your systems up and running.

Business Continuity.

This term refers to the business as a whole being able to function. It goes beyond just the IT systems within an organisation. A business continuity manager will be looking after the well-being of the building, the staff, any equipment required to fulfil contractual obligations, the environment and the IT systems. The role requires one to consider what the plan would be during an act of terrorism, natural disaster, economic disaster or a smaller break in communications. Business Continuity planning therefore covers a wide scope of detail and can be a very complex project. It will encompass many scenarios and include many different methods of how to deal with these – a bit like a risk assessment.

IT Resilience.

Resilience refers to the ability to quickly recover or spring back from difficulties. IT resilience therefore refers to the ability to restore a working IT environment following any incident that may mean usual function is impeded. Whether this is communications related, a hardware/software failure, or a fire that has taken hold of the server room. IT resilience will look at the process of getting everything back up and running as it was prior to the incident. This should also include the working environment e.g. desktops with which to access the IT systems.

Disaster Recovery.

Disaster Recovery is similar to IT resilience. It stops at the IT systems level though and doesn’t extend to the working environment e.g. desktop services. It is the process of restoring servers and infrastructure to deliver a fully working set of systems that the users can log into. This is providing that they have a computer and an internet connection.


Backup relates to data, or files and sometimes even individual servers. It typically means taking a copy of your data/files/server and storing it in a secure location. Should you accidentally delete a file or overwrite it then you can go to your backup archive and restore the data. It won’t help you in the event that multiple servers fail though and relies on your systems to be available in order to restore your data effectively.
