Is Your Disaster Recovery Plan Tested for Real Emergencies?
Your organization has backups. There is a disaster recovery document somewhere. The IT team knows which systems are critical.
Then, at 9:17 on a Monday morning, a core server becomes unavailable.
Employees cannot access an essential application. Customers are waiting. Management wants to know when services will return. The backup exists—but nobody has performed a full restoration recently.
Suddenly, the question is no longer “Do we have a disaster recovery plan?”
It is: “Does our disaster recovery plan actually work?”
For Ethiopian organizations becoming increasingly dependent on digital infrastructure, having a written disaster recovery plan is only the beginning. A plan that has never been tested contains assumptions, and emergencies have a habit of exposing them.
A Backup Is Not the Same as Recovery
This distinction is critical.
A backup means data has been copied somewhere. Disaster recovery means the organization can restore the required systems, applications, configurations, and data within an acceptable period.
A dashboard showing “Backup Successful” does not prove that the files are usable.
Can the backup actually be restored? Are application dependencies included? Does the team have the required credentials? How long would restoration take?
These questions should be answered during testing—not during an outage.
The 30-Minute Recovery That Takes Six Hours
Recovery estimates often look excellent on paper.
A team might assume a particular server can be restored within 30 minutes. During an actual test, however, they discover the backup takes 90 minutes to retrieve, configuration files are stored elsewhere, DNS changes are required, and nobody documented one application dependency.
Thirty minutes becomes six hours.
This is why organizations should define and test their Recovery Time Objective (RTO)—how quickly a service needs to return—and Recovery Point Objective (RPO)—how much recent data the business can tolerate losing.
Real testing reveals whether those targets are achievable.
Test the People, Not Just the Technology
Disaster recovery is also a human process.
Imagine the primary system administrator is unreachable when an incident occurs.
Can another engineer initiate recovery?
Does someone know where emergency credentials are stored? Who authorizes failover? Who contacts management? Who communicates with customers? Who works with an internet provider or technology vendor if external assistance is required?
A strong business continuity and disaster recovery strategy should remain usable even when key individuals are unavailable.
If recovery depends entirely on one employee's memory, the organization has another single point of failure.
Simulate Something Uncomfortable
A useful disaster recovery test should create realistic pressure without endangering production operations.
Instead of simply asking whether backups exist, simulate scenarios.
What happens if a critical virtual machine becomes unavailable?
Can operations continue if the primary internet connection fails?
What if ransomware makes production data inaccessible?
What if a server room experiences an extended power incident?
What if the primary site itself cannot be used?
Tabletop exercises can test decision-making, while controlled technical recovery exercises can verify that systems and data can actually be restored.
Every test should produce findings.
Watch the Clock
During a recovery exercise, record timestamps.
When was the incident identified? How long did escalation take? When did restoration begin? When did the application become accessible? When was normal operation confirmed?
This converts disaster recovery from assumptions into measurable performance.
If a business requires a system back within two hours but testing shows recovery takes five, management now has valuable information for improving infrastructure, procedures, redundancy, or backup architecture.
Your DR Plan Has an Expiration Date
Infrastructure changes constantly.
Servers are replaced. Applications move to the cloud. Employees leave. Passwords change. Vendors change. New systems become business-critical.
A disaster recovery plan written two years ago may describe an environment that no longer exists.
Organizations should therefore review and test recovery procedures regularly and after significant infrastructure changes.
