Disaster Recovery RPO/RTO Planner
Plan disaster recovery scenarios and estimate cost of downtime vs recovery speed. Enter values for instant results with step-by-step formulas.
Worked Examples
Example 1: Low Cost Strategy
Problem: RPO 24h, RTO 48h, $500/mo. Event Cost: $360k.
Solution: Cheap insurance, but a disaster will be catastrophic.
Result: High Risk / Low OpEx
Example 2: High Availability Strategy
Problem: RPO 1h, RTO 4h, $2000/mo. Event Cost: $22k.
Solution: Expensive insurance ($24k/yr), but saves $338k per event.
Result: Low Risk / High OpEx
Frequently Asked Questions
What is the RPO/RTO trade-off?
Lowering RPO/RTO (faster recovery) exponentially increases infrastructure costs (synchronous mirroring, hot standby). Increasing them lowers cost but raises business risk.
Does RPO include Ransomware?
Yes, but differently. For ransomware, you revert to a clean backup *before* the infection. Your RPO is effectively 'Time since infection', which could be days.
Why differentiate RPO and RTO?
They drive different costs. RPO drives Storage/Network cost (frequency of sync). RTO drives Compute/Automation cost (speed of boot/failover).
Why might my result differ from another tool or reference?
Differences typically arise from rounding conventions, the specific version of a formula (for example, simple vs compound interest), or unit inconsistencies between inputs. Check that both tools are using the same formula variant and the same units. The References section links to the authoritative source behind the formula used here.
What inputs do I need to use Disaster Recovery RPO/RTO Planner accurately?
Each field is labelled with the required unit (metric or imperial). Gather your source values before starting — for example, a weight measurement in kilograms, a distance in metres, or a dollar amount — and enter them exactly as measured. The formula section on this page lists every variable and explains what each represents.
How accurate are the results from Disaster Recovery RPO/RTO Planner?
All calculations use established mathematical formulas and are performed with high-precision arithmetic. Results are accurate to the precision shown. For critical decisions in finance, medicine, or engineering, always verify results with a qualified professional.
