The situation
What needs investigation
Backups may exist, but a team may not know how long a restore takes, whether it contains the required data, or which services and DNS changes must be recovered together. The review turns recovery requirements into a testable sequence.
Signals we look for
Recovery objectives
- RPO by data type
- RTO by service
- business priority
Backups
- coverage and retention
- encryption and access
- restore integrity
Dependencies
- database restore order
- identity and secrets
- DNS and external services
Runbooks
- ownership
- test schedule
- evidence and improvements
How we investigate
Each step is validated against the workload before the next change.
- 01
Set objectives
Define acceptable data loss and recovery time for each critical service.
- 02
Inventory recovery assets
Check backups, snapshots, infrastructure code, credentials, and documentation.
- 03
Map dependencies
Establish the order in which data, applications, identity, and traffic must return.
- 04
Rehearse restores
Restore representative data into an isolated environment and measure the process.
- 05
Plan regional events
Assess cross-region needs against data, latency, and operational cost.
- 06
Maintain runbooks
Record owners, decision points, contacts, and test results.

Engineering interpretation
A scheduled snapshot may meet the stated data-loss target, but only a restore test confirms the backup can be accessed, restored, validated, and connected to the dependent application.
Possible next investigation
- Restore into an isolated account or environment.
- Measure restore and validation steps.
- Verify encryption keys and access paths.
- Record the recovery order and manual decisions.
Trade-offs we consider
RPO
Lower data-loss tolerance normally requires more frequent or continuous protection.
RTO
Faster recovery often requires pre-built capacity and higher operating cost.
Region strategy
Cross-region recovery adds resilience and dependency complexity.
Test effort
A plan that is not exercised becomes less reliable over time.
