Why it matters
A backup is one ingredient of recovery, not a recovery promise. Customers need to know how long their workflow may be unavailable, how much recent work could be lost, and whether the team has actually restored the whole service.
Recovery time objective (RTO) is the maximum acceptable service interruption. Recovery point objective (RPO) is the maximum acceptable gap between the last usable data point and the interruption. Both are business choices that must be tested against the real dependency chain.
Decisions to make
- Choose RTO and RPO by customer workflow rather than giving every component one number.
- List the data, identity, files, keys, configuration, and external services needed to restore that workflow.
- Decide whether the plan uses backups, a warm standby, active regions, or a mix.
- Define who declares an incident, who authorizes recovery, and what customers are told.
- Choose how a restored dataset is checked for completeness and tenant isolation.
- Set a drill schedule and decide what evidence will support a customer commitment.
Build checklist
- Measure the last usable data point and elapsed recovery time during a rehearsal.
- Restore into an isolated location and verify reads, writes, login, and downstream work.
- Reconcile related data stores so files, events, and records describe a coherent point in time.
- Check keys, secrets, DNS, and third-party credentials are usable in the recovery location.
- Document failure, partial recovery, and failback steps with named owners.
- Record drill results and revise objectives when the measured result misses the target.
Common mistakes
- Calling a successful backup job proof that the application can be restored.
- Testing database restore while ignoring identity, files, keys, or outbound work.
- Publishing an RTO or RPO that has never been measured in a drill.
