Business Continuity & Disaster Recovery Guide

What this capability solves

BCDR turns outages, data loss, and infrastructure failures from unknown risks into planned recovery scenarios.

Common risks

Backups exist but restore testing is inconsistent or undocumented
Recovery time and recovery point objectives are not aligned with business needs
Critical systems have hidden dependencies that slow recovery
Infrastructure lacks fault tolerance or high-availability design
Data protection tools are not mapped to business-critical workloads

Data protection strategy

The best data protection solution depends on workload criticality, recovery objectives, retention needs, and operating model.

Review areas

Backup scope, frequency, retention, and immutability
Restore testing and evidence collection
Replication, snapshots, and offsite protection
Cloud, on-prem, and hybrid backup targets
Ransomware and accidental deletion recovery scenarios

Fault-tolerant infrastructure

Fault tolerance reduces single points of failure and improves service resilience.

Design considerations

High availability for compute, storage, networking, and identity dependencies
Virtualization cluster and workload placement review
Redundant network paths and power dependencies
Cloud availability zones, regions, or hybrid recovery targets
Monitoring and alerting for resilience failures

Recovery planning and testing

Plans are only useful when they are tested and maintained.

Recommended outputs

Execution view

Area	What to review	Output
Assess	Critical systems, dependencies, recovery objectives, data sensitivity, and outage impact	Business impact and resilience assessment
Protect	Backup coverage, retention, immutability, restore testing, and data loss scenarios	Data protection strategy
Design	High availability, replication, failover, cloud/on-prem/hybrid targets, and single points of failure	Fault-tolerant infrastructure plan
Validate	Restore testing, DR exercises, runbooks, communication, and evidence collection	Recovery validation report

Core principle

Business continuity and disaster recovery are not just backup tools. They are a business-aligned operating model for protecting data, reducing downtime, and validating that recovery actually works.
