* Recovery Point Objective (RPO) refers to the required point-in-time to which a DR solution can
restore the state of data for a particular service, for example, how much data loss is acceptable
following a disaster. These requirements can range from “close to zero” data loss (for high-value
financial transactions, for example) to some small number of minutes of the most recent data, to
loss of the past 1-2 days of data, depending on the criticality of the data to the enterprise.
