Definition
Recovery Point Objective (RPO) defines the maximum acceptable amount of data loss after an incident or failure, expressed as the point in time to which data must be recoverable.
Human Explanation
RPO answers the question: how much recent data can the organisation accept losing?
Why it Matters
It informs Backup frequency, replication design and the protection required for changing data.
Conceptual Boundary
RPO does not define how long system restoration may take; that is the role of RTO. An RPO of one hour does not mean recovery will finish within one hour.
Practical Perspective
A smaller RPO requires more frequent copying or continuous replication and must be verified against the actual ability to restore consistent, usable data.
