Abstract

An apparatus to compare two datasets, each of which includes multiple data blocks, includes a comparison unit and a report generator. The comparison unit identifies block-level differences therebetween, by comparing block-level metadata between the first and second datasets, without comparing the contents of the data blocks. The report generator generates a human-readable report of the differences between the first and second version of the dataset, including the differences in individual data blocks between the first and second version of the dataset.
