    摘要: In one aspect, a method to recover data includes annotating metadata entries in a journal to indicate changes by an application to an object stored in a continuous data protection environment. Each entry of the metadata corresponds to one of a unique group of DO stream data blocks or a unique group of UNDO stream data blocks. The method also includes determining a version of the object that meets criteria by searching the annotated entries and obtaining the version of the object that meets the criteria.In another aspect, a method to recover data includes receiving criteria to recover an object, determining a version of the object that meets the criteria by searching point-in-time images using a DO stream and an UNDO stream and obtaining the version of the object that meets the criteria.
