摘要: Systems and methods are disclosed for forming deduplicated images of a data object that changes over time using difference information between temporal states the object. The method includes organizing content first state as plurality segments storing in store; creating an organized arrangement hash structures to represent its state; receiving object; at least one signature changed content; is unique store segments, whereby image second stored without requiring reception complete state.
