Introduction
Most businesses have some form of backup in place. Far fewer have an actual disaster recovery plan — a tested, documented process for getting critical systems back online within an acceptable timeframe after an outage, cyberattack, or hardware failure. The difference between the two often only becomes clear during an actual incident, which is the worst possible time to discover the gap.
Backup vs Disaster Recovery: Not the Same Thing
| Backup | Disaster Recovery |
| Copies of data stored for retrieval | A complete plan for restoring systems and operations |
| Answers: “Can we get the data back?” | Answers: “How fast can we be fully operational again?” |
| Necessary but not sufficient on its own | Includes backups plus infrastructure, roles, and tested procedures |
Key Concepts: RTO and RPO
Recovery Time Objective (RTO): How long the business can tolerate a system being down before serious harm occurs. This determines how much investment in redundancy and fast-recovery infrastructure is justified.
Recovery Point Objective (RPO): How much data loss is acceptable, measured in time — for example, an RPO of 1 hour means backups need to run at least hourly to meet that target.
Building a Disaster Recovery Plan
- Identify critical systems and set RTO/RPO for each. Not every system needs the same level of protection — prioritize based on business impact.
- Document step-by-step recovery procedures. Specific enough that someone other than the usual expert could follow them under pressure.
- Define roles and communication plans. Who does what, and how the team and customers are communicated with during an incident.
- Store backups off-site and offline where possible. Protects against scenarios like ransomware that specifically target connected backups.
- Test the plan regularly. A disaster recovery plan that has never been tested is a document, not a real capability.
Common Disaster Recovery Gaps
- Backups exist but have never been tested for successful restoration
- No documented plan beyond “IT will handle it” — with no specifics if that person is unavailable
- Recovery plan doesn’t account for ransomware specifically targeting connected backup systems
- No defined communication plan for customers or stakeholders during an extended outage
A Simple Readiness Checklist
- Critical systems identified with RTO/RPO defined for each
- Backups automated, stored off-site, and tested for successful restoration
- Written, specific recovery procedures exist for critical systems
- Roles and communication plan documented for incident response
- Disaster recovery plan has been tested within the last 12 months
Final Thoughts
Disaster recovery planning is one of those investments that’s easy to deprioritize until the moment it’s the only thing that matters. A tested plan, built around clear recovery targets, is what separates a serious outage from a business-ending one.
