In continuous data protection (CDP), journal space stores all the changes made to data over time. The amount of journal space determines the retention window, i.e., how far back in time data can be recovered. A larger journal allows for a longer recovery window.
Amount of space the source and replica volumes require:Relates to storage capacity, not recovery time.
Length of time required to recover the data:Depends on system performance and data size.
Amount of data that can be restored to a specific point:Depends on the changes captured in the journal.
