This paper proposes a parity structure for large remotely located replicated data files. The parity structure can accomplish the following objectives. 1) Ascertain with a high degree of confidence whether two or more files are identical, using a very small amount of communication. 2) If there is disagreement between two files, the disagreeing portion can be located simply and with a small amount of communication. 3) Memory faults within each individual file can be detected simply and with high probability.
