Plan recovery with RPO and RTO
See this course’s project requirements
A fictional cloud-service architecture packet with workload and data flow, responsibility boundary, least-privilege role matrix, unit-based cost and egress budget, recovery table and supported service decision.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Create a unit-labeled workload, minimal-data flow, and explicit planning-assumption register.
- Produce a service-specific provider/customer matrix and a list of real-contract questions.
- Create task-based allowed/denied role cases and clearly mark the access matrix as design evidence.
- Deliver independently checked baseline and stress costs, reserve totals, and a budget-review condition.
- Create a recovery timeline and validation checklist with distinct RPO/RTO targets and unexecuted limits.
- Deliver a supported architecture decision with calculation evidence and unresolved real-service questions.
Review and revise
Use these criteria to check your work and choose what to improve.
- The implementation or declared simulation follows the supplied contract and retains inspectable original inputs.
- Normal, boundary and rejected cases are recorded with expected versus observed results.
- The changed case has a correct explanation and does not rely on hidden state.
- The project includes source, outputs, instructions and honest tool, privacy and verification limits.

The idea in everyday life
Fictional reference-card service: 1000 requests/month, 20 budgeted compute hours, 2 GB stored, 4 GB outbound. Invented rates: $0.05/hour, $0.20/GB-month storage, $0.10/GB outbound, $2/month fixed; 25% reserve and $6/month budget. These are exercise assumptions, not provider prices or measured workload forecasts.
RPO limits acceptable data-loss time; RTO limits restoration time. A backup’s existence does not prove it can be restored and validated within the target.
Plan recovery with RPO and RTO — original worked practice
RPO limits acceptable data-loss time; RTO limits restoration time. A backup’s existence does not prove it can be restored and validated within the target.
Fictional reference-card service: 1000 requests/month, 20 budgeted compute hours, 2 GB stored, 4 GB outbound. Invented rates: $0.05/hour, $0.20/GB-month storage, $0.10/GB outbound, $2/month fixed; 25% reserve and $6/month budget. These are exercise assumptions, not provider prices or measured workload forecasts.
1. Step 1
Use a 24-hour backup interval and a stated RPO target of 24 hours for fictional public cards.
You should see: The worst interval-based loss window is up to 24 hours under this assumption.
RPO limits acceptable data-loss time; RTO limits restoration time. A backup’s existence does not prove it can be restored and validated within the target.
2. Step 2
Plan restore 2 hours, validate 0.5 hour, switch 0.25 hour; add the three stages.
You should see: Planned recovery duration is 2.75 hours, below the 4-hour RTO target.
RPO limits acceptable data-loss time; RTO limits restoration time. A backup’s existence does not prove it can be restored and validated within the target.
3. Step 3
Tabletop outage at 10:00 using a midnight backup; record 10 hours of possible changes to reconstruct.
You should see: The specific loss window is 10 hours, not the full worst-case interval.
RPO limits acceptable data-loss time; RTO limits restoration time. A backup’s existence does not prove it can be restored and validated within the target.
4. Step 4
Write a restore-validation checklist: correct version/count, usable cards, authorized switch, and rollback decision.
You should see: A recovery tabletop with RPO/RTO and unexecuted restore limits.
RPO limits acceptable data-loss time; RTO limits restoration time. A backup’s existence does not prove it can be restored and validated within the target.
What to finish
Create a recovery timeline and validation checklist with distinct RPO/RTO targets and unexecuted limits.
Watch for this
Confusing data-loss interval with recovery duration or treating a tabletop as an executed restore.
How can I tell I understand it?
Demonstrate the rule: RPO limits acceptable data-loss time; RTO limits restoration time. A backup’s existence does not prove it can be restored and validated within the target. Use the supplied variant to distinguish a changed result from a broken implementation.
