An approach is provided for providing criticality based data backup. A data backup platform determines one or more state trajectories associated with one or more information management processes operating on at least one information space. The data backup platform further processes and/or facilitates a processing of the one or more state trajectories to determine criticality information associated with one or more data items of the at least one information space. The data backup platform also determines (a) one or more data backup processes, (b) one or more data restoration processes, (c) one or more parameters for the one or more data backup processes, the data restoration processes, or a combination thereof, or (d) a combination thereof based, at least in part, on the criticality information.
