Why DR is Business Survival, Not IT Overhead
Ransomware, hardware failure, or cloud outages all kill availability. Without tested backups and recovery, firms collapse.
Practical Strategy
- 3-2-1 Rule: 3 copies, 2 media types, 1 offsite.
- Encryption at rest + transit.
- Automated verification: test restores weekly.
- Documented RTO/RPO targets aligned to business needs.
Applied Example
- Small business server hit by ransomware.
- Local backups encrypted too → only offsite S3 bucket with immutability saved them.
Why Clients Care
- DR readiness is a board-level issue.
- ISO 22301 and ISO 27001 require it.
- Direct link to resilience and client trust.
