Building a smart disaster recovery solution with minimal tools
Smart DR is not minimum-viable DR — it is DR stripped of everything that does not earn its place. The three non-negotiables and the five-step minimal programme.
Definition
Smart DR — a tested, defensible recovery capability for every system the business genuinely depends on, using the smallest possible toolset and the lowest practical cost. Defined less by what it contains than by what it consistently does.
A smart disaster recovery solution delivers a tested, defensible recovery capability for every system the business genuinely depends on, using the smallest possible toolset and the lowest practical cost. Enterprise DR platforms cost enterprise money — but the principles of effective DR cost nothing beyond the time and discipline to implement them. Technology is rarely the constraint. Discipline is.
The three non-negotiables
A current, tested backup of every critical system
Stored in a location physically and logically separate from the primary infrastructure. Same building, same network, same credentials does not count.
A documented runbook for each critical system
A competent responder can follow it under pressure without the person who wrote it in the room. Tribal knowledge is not a runbook.
At least one person who has practised the recovery
Not read it — practised it. Recovery is an operational skill, not a reading exercise.
Native cloud tools that cost little or nothing extra
AWS Backup handles EC2, RDS, S3, and DynamoDB centrally. Azure Backup and Azure Site Recovery provide VM-level backup and orchestrated failover. Google Cloud Backup and DR provides managed backup for GCP workloads. For offsite copies, Backblaze B2 (quarter the price of S3) and Cloudflare R2 (zero egress fees) dramatically change the economics of keeping data safely separated.
"Your most important DR tool costs nothing: a runbook that has been tested by the people who would use it."
Building towards maturity
Level 1 — Initial
Some backups exist. Recovery undocumented and untested. DR is theoretical.
Level 2 — Developing
Critical systems identified. Backups running on schedule. Rudimentary runbooks exist but untested.
Level 3 — Defined
All critical systems covered. Runbooks written and tested. Annual recovery exercise documented. The level at which DR becomes credible to an auditor or board.
Level 4 — Managed
SLAs defined and tracked. Testing regular. Immutable copies in place. Practice built into the operating rhythm.
Level 5 — Optimised
Recovery automated where appropriate. Continuous improvement built in. Quarterly testing routine, not exceptional.
Closing
The best disaster recovery solution is the one you will actually implement, test, and maintain. A sophisticated enterprise DR architecture that is never tested is inferior to a minimal verified backup and a practised runbook. Start minimal. Make it real. Test it. Then improve.
