System and method for creating deduplicated copies of data by tracking temporal relationships among copies using higher-level hash structures

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. also determining, subsequent deduplicating store, whether should be stored by searching higher-level structure global cache store.
