In order to obviate data discrepancy between a primary source database and a secondary remote backup database, a Tracker program is used to sense the lack of synchronism between a primary audit file and secondary audit file. Then, a Catch-up program operates to transfer sectioned audit files from the primary to secondary in a parallel transfer mode until the primary and secondary audit files are accurate duplicates of each other, i.e., they are now in synchronism.
