A method is described. The method includes processing first meta data for first units of stored content in a first storage system. The processing includes constructing a first tree of first nodes where first lower nodes represent fewer of the first units of stored content and first higher nodes represent more of the first units of stored content. The first nodes include respective first hash values calculated from the first meta data to represent the respective content of the respective first units of stored content that the first nodes respectively represent. The method includes processing second meta data for second units of stored content in a second storage system. The processing includes constructing a second tree of second nodes where second lower nodes represent fewer of the second units of stored content and second higher nodes represent more of the second units of stored content. The second nodes include respective second hash values calculated from the second meta data to represent the respective content of the respective second units of stored content that the second nodes respectively represent. The method includes comparing at least a subset of the first hash values with a corresponding at least a subset of the second hash values to ascertain sameness between the first and second units of stored content.
