Design for Recovery Before Disruption Happens

Plan how critical systems and data will be protected, restored, and validated when an outage affects normal operations.

A disaster recovery architecture defines how a business will recover important applications, infrastructure, and data after a disruptive event. This reference design helps organizations identify recovery dependencies, choose appropriate protection patterns, and establish measurable recovery objectives.

Reference Architecture

Typical Pattern: production environment → protected backup repository and/or replication → separate recovery environment or region → controlled restoration or failover.

Separate backup credentials and access paths where practical
Consider immutable or isolated backup options where supported
Identify dependencies such as identity, DNS, networking, certificates, and third-party services
Define approval and communication steps for failover and restoration
Keep recovery documentation accessible during a primary-site outage

Recovery Objectives

Recovery planning should define two key targets.

Recovery Point Objective (RPO): The amount of data loss the business can tolerate, expressed as time
Recovery Time Objective (RTO): The target time to restore a service
Set targets by application criticality rather than assuming one target fits all systems
Validate that the selected architecture and budget can support the targets

Testing and Governance

A plan is useful only when the organization can execute it.

Potential Deliverables

The agreed scope may include:

Frequently Asked Questions

Does replication replace backups?

No. Replication can reproduce unwanted changes or corruption. A resilient strategy typically considers both recovery copies and replication where appropriate.

Can recovery time be guaranteed?

Recovery targets are planning objectives, not universal guarantees. Achievability depends on architecture, dependencies, providers, testing, and incident conditions.
