RPO
Recovery Point Objective
The maximum acceptable amount of data loss measured in time.
Recovery Point Objective defines the maximum acceptable amount of data loss measured as a span of time, effectively answering how far back a recovery can fall. It directly drives backup frequency, since an RPO of one hour requires backups or replication at least that often. The common contrast is with Recovery Time Objective, which sets how quickly systems must be restored rather than how much data may be lost. Both are central metrics in business continuity and disaster recovery planning.
Recovery POINT objective: how much data you can afford to lose, measured back to your last good backup. RPO = data.
Looking RPO up is step one. Getting tested on it is step two.
