Disaster Recovery Test Plan

1. Purpose

The Disaster Recovery Test Plan defines how the organization will plan, conduct, evaluate, and document tests of its disaster recovery capabilities.

The objective is to demonstrate that critical technology services, information, infrastructure, security controls, and supporting dependencies can be recovered within defined recovery requirements.

A DR test should demonstrate actual capability—not simply confirm that a recovery document exists.

Core principle:

Plan → Test → Measure → Evidence → Identify Gaps → Correct → Retest → Improve

2. Scope

This plan may cover:

Cloud infrastructure
Production applications
Databases
Storage
Networks
DNS
IAM and authentication
Security controls
Backup and restore
Monitoring and logging
Source code
CI/CD
Infrastructure as Code
Secrets and encryption keys
Critical SaaS services
Third-party technology dependencies
Suppliers
Recovery personnel
Business validation
Customer communication
Incident response integration

The exact scope should be determined based on business criticality, risk, RTO/RPO, dependencies, and the type of test.

3. Test Objectives

Each DR test should have clearly defined objectives.

Typical objectives include:

Verify that critical systems can be recovered.
Verify that backups can actually be restored.
Measure actual recovery time.
Measure actual data recovery point.
Validate RTO and RPO requirements.
Validate recovery dependencies.
Validate emergency access.
Validate emergency change procedures.
Validate security controls during recovery.
Validate communication and escalation.
Identify single points of failure.
Identify gaps in recovery documentation.
Verify recovery personnel understand their responsibilities.
Validate supplier/cloud recovery capabilities.
Generate evidence for management and audit.
Identify corrective actions and improvements.

4. When to Perform a DR Test

A DR test should be planned based on risk and business requirements.

Testing may be triggered by:

Major infrastructure changes
Cloud architecture changes
New critical applications
Significant business changes
New suppliers
Major security changes
Changes to RTO/RPO
Significant incidents
Backup failures
Previous DR test findings
Major technology migrations
Regulatory or contractual requirements
Significant changes to recovery procedures

Testing frequency should be defined by the organization based on risk and criticality rather than assuming a universal frequency.

5. Types of DR Tests

Different tests provide different levels of assurance.

Test Type	Purpose
Document Review	Verify recovery documentation remains accurate
Walkthrough	Review recovery steps with responsible personnel
Tabletop Exercise	Test decisions and coordination using a scenario
Backup Restore Test	Demonstrate backup restoration
Technical Recovery Test	Recover selected technology components
Application Recovery Test	Recover and validate an application
Database Recovery Test	Restore and validate databases
Failover Test	Test switching to an alternate environment
Cloud Recovery Test	Recover cloud infrastructure/services
Supplier Recovery Test	Validate critical supplier recovery capability
Communication Test	Test emergency communication
Full DR Simulation	Test multiple recovery capabilities together
Live Failover	Perform controlled production failover where justified

A startup should normally begin with lower-risk tests and progressively increase test depth.

6. DR Test Identification

Each test should have a unique identifier.

Example:

DRT-2026-001

Field	Example
Test ID	DRT-2026-001
Test Name	Production SaaS Recovery Test
Test Date	15-Nov-2026
Test Owner	DR Coordinator
Test Type	Technical Recovery
Scenario	Primary cloud environment unavailable
Environment	Non-production recovery environment
Related BCP	BCP-2026-001
Related DR Plan	DRP-2026-001
Related RTO/RPO	RTO-2026-001
Status	Planned

7. Test Classification

The organization should define the level of testing.

Level 1 – Document Test

Verify:

Recovery documentation
Contact information
Dependencies
Recovery procedures
System information
RTO/RPO requirements

Level 2 – Tabletop Test

Participants discuss a disaster scenario and explain what they would do.

Level 3 – Component Recovery Test

Recover selected components such as:

Database
Storage
Application
IAM
Network
Backup

Level 4 – End-to-End Recovery Test

Recover multiple technology components and validate the complete service.

Level 5 – Full Simulation / Failover

Simulate or execute a significant recovery scenario involving multiple teams and dependencies.

8. Test Scenario

Every test should have a defined scenario.

Example

Scenario: Primary AWS Production Environment Unavailable

Assume that the organization’s primary production environment becomes unavailable due to a major infrastructure failure.

The test will determine whether the organization can:

Activate the DR process
Establish recovery ownership
Access required recovery accounts
Restore infrastructure
Restore database
Restore application
Restore storage
Configure networking
Restore secrets/configuration
Validate security controls
Validate application functionality
Validate data integrity
Resume critical customer service

The scenario should identify assumptions and limitations so that test results are not misunderstood.

9. Test Assumptions

Document assumptions before the test.

Examples:

Production will not be intentionally disrupted.
Recovery will be performed in a separate environment.
Test data will be used where appropriate.
Cloud provider services remain available.
Required personnel are available.
Recovery credentials are available.
Backups are available.
DNS changes will not affect production.
Customer communication will be simulated.

Any assumption that differs from real-world conditions should be documented as a test limitation.

10. Test Scope

Document exactly what will and will not be tested.

Component	In Scope	Validation
AWS Account	Yes	Access
IAM	Yes	Authentication/authorization
VPC	Yes	Network connectivity
Security Groups	Yes	Security
WAF	Yes	Traffic protection
S3	Yes	Data restoration
RDS	Yes	Database restoration
ECS	Yes	Application recovery
Secrets Manager	Yes	Secret recovery
KMS	Yes	Encryption
DNS	Yes	Service resolution
Monitoring	Yes	Logging/alerts
Customer Communication	Simulation	Communication
Production Traffic	No	Out of scope

11. Test Participants

Identify participants before the test.

Typical participants:

Executive Management
DR Coordinator
Incident Commander
Security Lead
Cloud/Infrastructure Lead
Application Lead
Database Administrator
DevOps Engineer
Business Owner
Supplier/Vendor Owner
Privacy/Legal
Customer Success/Communications
IT Support
Tester/Observer

For a startup, one person may perform multiple roles. The role assignments should still be explicitly documented.

12. Roles and Responsibilities

Role	Responsibility
DR Coordinator	Plans and coordinates the test
Test Owner	Owns test objectives and results
Cloud Lead	Performs cloud recovery
Application Lead	Validates application recovery
DB Owner	Performs database recovery
Security Lead	Validates security controls
Business Owner	Performs business validation
Communications	Tests stakeholder communication
Observer	Records actions and observations
Management	Reviews results and corrective actions

13. Pre-Test Preparation

Before starting the test:

Confirm test objectives.
Confirm scope.
Confirm participants.
Review RTO/RPO.
Review critical dependencies.
Confirm backups.
Confirm recovery environment.
Confirm recovery credentials.
Confirm emergency access.
Confirm required tools.
Confirm communication channels.
Review security requirements.
Review rollback arrangements.
Review test assumptions.
Confirm production protection.
Confirm evidence collection method.

14. Backup Validation Before Test

Before attempting recovery, verify that the selected recovery points are available.

Check:

Backup date/time
Backup status
Backup completeness
Encryption
Backup integrity
Retention status
Recovery point
Restoration method
Access permissions
Dependencies
Backup age

The test should not assume that a successful backup job automatically means successful recovery.

15. Recovery Environment

Define where recovery will occur.

Possible environments:

Alternate cloud region
Separate AWS account
Disaster recovery environment
Isolated recovery network
Non-production environment
Dedicated recovery infrastructure

The recovery environment should provide sufficient security controls for the test.

16. Recovery Sequence

Recovery should follow a controlled dependency sequence.

Example AWS SaaS recovery sequence

AWS Account

↓

IAM / Security

↓

VPC / Network

↓

Security Groups / WAF

↓

S3 / Storage

↓

RDS / Database

↓

ECS / EKS / EC2

↓

Secrets / KMS

↓

Load Balancer

↓

DNS

↓

Monitoring / Logging

↓

Application Validation

↓

Business Validation

The exact sequence should reflect the organization’s architecture.

17. Test Timeline

Record significant events during the exercise.

Time	Event	Owner	Evidence	Status
09:00	Test started	DR Coordinator	Test record	Completed
09:10	Recovery activated	DR Team	Decision log	Completed
09:20	Recovery environment prepared	Cloud Lead	Cloud evidence	Completed
09:40	Database restoration started	DB Owner	Backup record	Completed
10:15	Application restored	App Lead	Deployment record	Completed
10:40	Security validation	Security Lead	Checklist	Completed
11:00	Business validation	Business Owner	Validation record	Completed

Record actual times rather than planned times.

18. RTO Measurement

Measure the actual recovery time.

Example:

Recovery start: 09:10
Service available: 11:00

Actual recovery time = 1 hour 50 minutes

If the defined RTO is 4 hours:

Result: RTO achieved

However, the conclusion should be based on actual evidence from the test.

19. RPO Measurement

Measure how much data was lost or could not be recovered.

Example:

Last usable recovery point: 08:00
Disruption point: 08:45

Actual RPO = 45 minutes

If the defined RPO is 1 hour:

Result: RPO achieved

RPO should be measured from the actual recovery point rather than simply relying on the backup schedule.

20. Infrastructure Recovery Test

Validate:

Cloud account access
IAM
Network
VPC
Subnets
Security groups
WAF
Load balancers
Compute
Storage
DNS
Infrastructure as Code
Monitoring
Logging

Record:

Start time
Completion time
Errors
Manual interventions
Evidence
Recovery dependencies

21. Database Recovery Test

Validate:

Backup availability
Recovery point
Database restoration
Database connectivity
Schema integrity
Data integrity
Application connectivity
Security configuration
Encryption
User permissions
Performance where relevant

The test should confirm that the restored database is usable by the application.

22. Application Recovery Test

Validate:

Application deployment
Configuration
Dependencies
APIs
Database connectivity
Authentication
Authorization
Secrets
Certificates
Network connectivity
Application functionality
Monitoring
Logging

Perform defined functional tests after recovery.

23. Data Integrity Validation

Recovery should not be considered successful merely because systems are online.

Validate:

Expected records exist
No unexpected corruption
Database consistency
File/object availability
Application data accessibility
Referential integrity where applicable
Encryption
Access permissions
Expected transaction state

Document the validation performed and the evidence obtained.

24. Security Validation

Security controls must be validated after recovery.

Check:

IAM
MFA
Least privilege
Privileged access
Network controls
Security groups
WAF
Encryption
KMS
Secrets
Logging
Monitoring
Vulnerability controls
Endpoint/security tooling
Backup protection
Configuration baselines

Important:

A system being successfully restored does not prove that it has been securely restored.

25. Business Validation

The Business Owner should confirm that the recovered service can support the required business activity.

Examples:

User login works.
Customer application works.
Critical transactions work.
Required data is available.
Customer-facing functionality operates.
Business process can continue.
Security controls remain effective.

Technical recovery and business recovery should be recorded separately.

26. Emergency Access Test

Where emergency access is part of recovery, verify:

Emergency access request
Authorization
MFA
Least privilege
Time limitation
Activity logging
Monitoring
Access revocation
Post-test review

The test should confirm that emergency access does not become permanent access.

27. Emergency Change Test

Where emergency changes are required, verify:

Change identification
Risk assessment
Approval
Implementation
Backup/rollback
Testing
Security validation
Monitoring
Post-implementation review
Conversion to normal change management

28. Communication Test

Test communication to appropriate stakeholders.

Possible communication paths:

Incident Response Team
Management
Technology teams
Business owners
Suppliers
Cloud providers
Customers
Legal/Privacy
Regulators where applicable

For a tabletop or simulated communication test, clearly mark communications as TEST to avoid accidental external notification.

29. Supplier Dependency Test

Where critical suppliers are part of recovery, validate:

Supplier availability
Support contacts
Escalation path
Contractual commitments
Recovery commitments
Alternate arrangements
Dependency on supplier systems
Communication process

Examples:

AWS
Identity provider
Payment provider
DNS provider
Email provider
Critical SaaS provider

30. Test Observations

Record what actually happened.

Observation	Expected	Actual	Impact
Recovery credentials available	Yes	Yes	None
Database restore	<60 min	75 min	RTO risk
Application configuration	Automated	Manual	Improvement
Monitoring	Automatic	Partial	Gap
DNS recovery	<15 min	10 min	None

Observations should distinguish facts from assumptions.

31. Test Findings

Classify findings appropriately.

Examples:

Documentation gap
Configuration gap
Backup gap
Recovery capability gap
Security control gap
Dependency gap
Personnel gap
Supplier gap
RTO gap
RPO gap
Communication gap
Monitoring gap
Training gap

Each significant finding should be linked to a corrective action or risk decision.

32. Corrective Action Plan

Finding	Risk	Action	Owner	Target Date	Evidence	Status
DB recovery exceeded target	Medium	Optimize restore process	DB Owner	30-Nov	Test report	Open
Manual configuration required	Medium	Automate IaC recovery	Cloud Lead	15-Dec	Git commit	Open

Actions should be tracked in the organization’s Corrective Action Tracker.

33. Test Result Classification

A simple organizational classification can be used:

Successful

Objectives achieved and recovery requirements demonstrated.

Successful With Findings

Core recovery objectives achieved but improvement opportunities were identified.

Partially Successful

Some objectives were achieved but one or more significant recovery requirements were not demonstrated.

Unsuccessful

Critical recovery capability could not be demonstrated.

The classification should be supported by evidence rather than subjective assessment.

34. Test Limitations

Document limitations such as:

Production failover was not performed.
Customer traffic was simulated.
Certain suppliers were not involved.
Some infrastructure was manually recreated.
Recovery was performed using test data.
Full-scale disaster conditions were not simulated.
Certain external dependencies were assumed available.

A limitation should not be hidden; it defines what the test did not prove.

35. Test Evidence

Collect appropriate evidence such as:

Test plan
Test approval
Test scenario
Participant list
Timeline
Backup records
Restore logs
Cloud configuration
AWS console evidence
CloudTrail records
Deployment records
Infrastructure-as-Code records
Database validation
Application validation
Security validation
Screenshots where appropriate
Monitoring alerts
Communication records
Decision logs
RTO/RPO measurements
Findings
Corrective actions
Test report

Evidence should be stored according to the organization’s evidence-management requirements.

36. Retest Requirements

A retest should be considered when:

Critical recovery capability failed.
RTO/RPO requirements were not achieved.
Major findings were identified.
Recovery procedures were significantly changed.
Critical corrective actions were implemented.
Backup or restore capability was changed.
Significant architecture changes occurred.

The retest should verify that the identified weakness has actually been addressed.

37. Management Review

Management should review significant DR test results.

Management review may include:

Test objectives
Recovery performance
RTO/RPO results
Significant findings
Security issues
Business impact
Supplier issues
Corrective actions
Residual risks
Resource requirements
Recovery strategy changes
Retest requirements

Management decisions should be documented.

38. DR Test Record

Each completed test should retain a formal record containing:

Field	Description
Test ID	Unique identifier
Scenario	Disaster scenario
Scope	What was tested
Objectives	What the test intended to prove
Participants	People involved
Start Time	Actual start
End Time	Actual completion
RTO	Target and actual
RPO	Target and actual
Recovery Results	What was recovered
Security Results	Security validation
Business Results	Business validation
Findings	Identified gaps
Corrective Actions	Required improvements
Limitations	What was not proven
Evidence	Supporting records
Conclusion	Overall test result
Approval	Responsible management approval

39. Startup Implementation

A startup does not need to begin with a large-scale disaster simulation.

A practical approach is:

Stage 1

Review DR documentation.
Review critical dependencies.
Confirm RTO/RPO.
Verify backup availability.

Stage 2

Perform backup restoration.
Restore a database.
Restore an application.
Validate data.

Stage 3

Test AWS/cloud recovery.
Test IAM and emergency access.
Test application recovery.
Measure RTO/RPO.

Stage 4

Conduct an end-to-end DR exercise.
Include security validation.
Include business validation.
Test communication.

Stage 5

Correct findings.
Retest critical gaps.
Update DR documentation.
Report results to management.

40. Relationship With Other ISMS Records

The DR Test Plan should connect with:

Business Impact Assessment

↓

Critical Service Register

↓

RTO/RPO Assessment

↓

ICT Dependency Register

↓

Backup & Restore Procedure

↓

Disaster Recovery Plan

↓

DR Test Plan

↓

DR Test Report

↓

Findings / Corrective Action Tracker

↓

Risk Reassessment

↓

ISMS Improvement Log

This creates a traceable relationship between recovery requirements, recovery capability, testing, findings, and improvement.

41. ISO/IEC 27001 Alignment

The DR test process should be risk-based and integrated into the organization’s ISMS.

Relevant areas may include:

Information security continuity
ICT readiness for business continuity
Backup
Redundancy
Logging and monitoring
Access control
Authentication
Configuration management
Incident management
Supplier security
Change management
Risk treatment
Continual improvement

The exact controls and testing requirements should be determined based on the organization’s risk assessment, applicable requirements, Statement of Applicability, business continuity requirements, and contractual/regulatory obligations.

ISO/IEC 27001 does not prescribe one universal DR test scenario, RTO, RPO, or test frequency.

42. Audit Evidence

An auditor should be able to trace:

Recovery Requirement

→ RTO/RPO

→ Critical Service

→ Dependency

→ Recovery Strategy

→ DR Procedure

→ DR Test Plan

→ Actual Test

→ Evidence

→ Measured RTO/RPO

→ Findings

→ Corrective Actions

→ Retest

→ Risk Reassessment

→ Management Review

This demonstrates that the organization is not simply maintaining a DR document—it is testing whether the capability works.

43. Final Audit Trail

→ Management Review Completed

→ DR Capability Improved

44. Final Principle

A Disaster Recovery Test Plan is not designed to prove that the recovery plan exists. It is designed to prove whether the organization can actually recover critical services securely, within its defined recovery requirements, and with sufficient evidence to demonstrate the result.

Plan → Recover → Measure → Validate → Identify Gaps → Correct → Retest → Improve
