Most organizations that think about disaster recovery think about data. Backups run, copies exist offsite, and there is a general confidence that files could be restored. That confidence addresses one failure mode and leaves several others entirely unexamined.
Data is recoverable. The question that determines whether an organization continues operating is broader: where do people work, how do they reach customers, which processes must continue immediately and which can pause, who decides what, and how does anyone know what is happening. An organization with perfect backups and no answer to those questions is not prepared.
That broader discipline is what distinguishes business continuity from Backup Solutions & Data Protection alone, and the planning work is more about the operation than about the technology.
Working Out What Actually Matters
The foundation is understanding which functions are critical and how quickly each must resume, which requires business input rather than technical judgment.
List the functions the organization performs, in business terms rather than system terms.
For each, establish the consequence of interruption over time. Some functions can pause for a week with minor inconvenience. Others cause contractual, regulatory, or reputational damage within hours.
Identify dependencies, meaning what each function requires: systems, data, people with specific knowledge, facilities, suppliers, and connectivity.
Note the constraints that are not technological, including staff who are the only ones who know how something works, and suppliers whose absence stops the process regardless of your own readiness.
Establish peak periods, since the impact of an interruption varies enormously by timing for many organizations.
The output is a prioritized list, and it invariably differs from what the technical team assumed. Functions that consume most of the IT budget are sometimes less time-critical than ones that receive little attention.
The Scenarios Worth Planning For
Different disruptions require different responses, and planning for one does not cover the others.
Facility loss, whether through fire, flood, or damage, means the building is unavailable and the plan needs an answer about where work happens.
Extended power or connectivity failure affects operations even where systems are intact.
Cyber incident, particularly ransomware, differs from other scenarios because systems may be intact but untrustworthy, and recovery involves rebuilding rather than restarting.
Key supplier failure, including a cloud service provider outage, affects organizations that have concentrated dependencies.
Personnel unavailability, whether from illness affecting many staff simultaneously or from the departure of someone holding critical knowledge.
Regional events, which in some areas are seasonal and predictable enough to plan for specifically.
The plan does not need a separate document for each. It needs to have considered whether the response would differ, and where it would.
Continuity Rather Than Recovery
The distinction matters because the objectives are different.
Recovery restores what was lost. Continuity keeps the organization functioning during the interruption, which may involve doing things differently rather than restoring the normal arrangement.
Alternative working arrangements need thinking through: whether staff can work remotely, what they need to do so, and whether the necessary access and equipment exist before they are needed.
Manual processes for critical functions are worth documenting, since an organization that can take orders on paper for two days is in a different position from one that cannot operate at all.
Communication arrangements, meaning how staff, customers, and suppliers are informed, need to work when normal systems do not. Contact information stored only in an inaccessible system is a common and avoidable failure.
Authority and decision-making should be clear in advance, including who has authority to invoke the plan and to make expenditure decisions during a disruption.
Alternate facilities, whether a second location, a reciprocal arrangement, or a plan for distributed working, answer the where question.
The Technical Foundation
The data protection layer supports all of this and its design should follow the requirements rather than preceding them.
Recovery objectives per system, derived from the business analysis rather than applied uniformly, determine backup frequency and recovery method.
Geographic separation of copies, since a backup in the same building as the primary system does not survive a building-level event.
Immutable copies that cannot be altered or deleted, which is the specific control that addresses ransomware.
System recovery capability rather than only file recovery, since restoring documents does not restore an application.
Documented restoration procedures, accessible without the systems being recovered, and current rather than describing an environment from three years ago.
Tested restoration, with the time taken measured against the requirement, because an untested recovery is a hypothesis.
Testing the Plan Rather Than Filing It
Plans that are written and never exercised fail predictably when used.
Tabletop exercises, where relevant people talk through a scenario, surface gaps cheaply and reveal the assumptions nobody stated.
Technical recovery testing verifies that systems can actually be restored within the required time.
Full exercises, where the organization operates under simulated conditions, are more disruptive and considerably more revealing.
Testing after changes matters, since new systems and modified environments break assumptions quietly.
Involving the people who would actually respond, rather than only those who wrote the plan, identifies the knowledge that exists only in one person’s head.
Documenting what was learned and updating the plan accordingly is the step that converts an exercise into an improvement.

Keeping It Alive
Continuity planning decays faster than most documentation.
Assign ownership, since a plan nobody maintains becomes inaccurate within a year.
Review on a schedule, and after significant changes to systems, premises, staffing, or suppliers.
Keep contact information current, which is the element that goes stale fastest and matters most during an incident.
Maintain accessible copies, including outside the systems and premises the plan covers.
Brief new staff, particularly anyone with a role in the plan.
And keep it proportionate. A small organization does not need the documentation of a large one, and a short plan that is current and understood is worth considerably more than a comprehensive one nobody has read since it was written.
