Abstract:
A method for confirming replicated data at a data site, including utilizing a hash function, computing a first hash value based on first data at a first data site and utilizing the same hash function, computing a second hash value based on second data at a second data site, wherein the first data had previously been replicated from the first data site to the second data site as the second data. The method also includes comparing the first and second hash values to determine whether the second data is a valid replication of the first data. In additional embodiments, the first data may be modified based on seed data prior to computing the first hash value and the second data may be modified based on the same seed data prior to computing the second hash value. The process can be repeated to increase reliability of the results.
