Methods and apparatus, including computer program products, for insuring data consistency within a network of computer systems. The method includes, in a network, sending a first data object from a first system to a second system, storing a copy of the first data object in the second system, generating a second data object from the first data object, sending the second data object and the copy to the first system, and determining a match of the copy with a current state of corresponding data of the copy in the first system.
