When a disaster strikes — whether it's ransomware, a fire, a flood, or a server failure — the businesses that survive are the ones that had a plan. Those without one often close within a year.
What Is a Disaster Recovery Plan?
A disaster recovery (DR) plan is a documented process for restoring IT systems and data after a disruptive event. It answers the question: "What do we do when everything stops working?"
Key Metrics
Every DR plan should define two critical numbers:
- **Recovery Time Objective (RTO)** — How long can you afford to be without each system? For email, it might be 1 hour. For your archive server, 24 hours.
- **Recovery Point Objective (RPO)** — How much data can you afford to lose? If your RPO is 1 hour, you need backups at least every hour.
Building Your Plan
Step 1: Inventory Your Systems
List every system, application, and data store in your business. Rank them by priority:
- **Critical** — Must be restored within hours (email, CRM, financial system)
- **Important** — Can wait 24-48 hours (project files, internal tools)
- **Non-essential** — Can wait days (archives, old records)
Step 2: Document Recovery Procedures
For each critical system, document exactly how to restore it. Include:
- Software versions and configuration
- Where backups are stored
- Step-by-step restoration instructions
- Who is responsible for each step
Step 3: Test Regularly
A plan that's never been tested is a fantasy. Schedule disaster recovery tests at least twice a year. Simulate different scenarios:
- Server hardware failure
- Ransomware attack
- Building inaccessibility
- Cloud provider outage
Step 4: Keep It Updated
Your business changes. New software, new staff, new processes. Update your DR plan whenever significant changes happen. Review it annually at minimum.
Common Mistakes
- **No off-site backups** — If your office floods, your backup server in the server room goes too
- **Untested backups** — The worst time to discover your backup is corrupt is during a disaster
- **No contact list** — Who do you call? Document your IT provider, vendors, and emergency contacts
- **Assuming the cloud solves everything** — Cloud services can fail too. Plan for it.
South Africa-Specific Disaster Scenarios
South African businesses face some unique disaster scenarios that a generic DR plan won't cover. Load-shedding can knock out critical systems if you don't have adequate battery backup and generator coverage. Civil unrest or protests near your office might prevent staff from accessing the building for days. Water outages in certain municipal areas can damage server rooms if cooling systems fail. Your DR plan should specifically address these South Africa-specific risks.
DR Planning FAQ
Q: What's the difference between disaster recovery and business continuity?
A: Disaster recovery focuses specifically on restoring IT systems and data after an incident. Business continuity is broader — it covers how your entire business continues to operate, including manual workarounds, alternate locations, and communication plans. Ideally, you should have both.

Q: How much does a disaster recovery plan cost?
A: The planning itself can be done at minimal cost if you have the expertise in-house. For most SMBs, having a managed IT provider develop the plan as part of your service agreement is most cost-effective. The real costs come from the infrastructure needed to support recovery — off-site backups, redundant hardware, cloud failover — which typically add 15–25% to your IT infrastructure budget.
