发明名称 Eliminating duplicate blocks during backup writes
摘要 Embodiments of the present invention include creating a subsequent backup copy of a data set by storing a full backup copy of the data set to reflect a state of a data set including blocks of data, at a first point in time. At a second point in time, after the first point in time, changes to the data set are identified. Next, as part of the subsequent backup copy, only each block of the data set which has been changed or added since the first point in time is stored.
