<p>In a distributed system where data is maintained in at least two databases and the data comprises at least one data element, the amount of data transmitted during data recovery is minimized by comparing (210) a first total of the data element of the data in a first database with a second total of a corresponding data element of corresponding data in a second database. An updating procedure for the data element is initiated (213, 214) if the first total and the second total are not the same.</p> |
