Jay Gourley said: Thanks, Sherlock and Anja. Your replies answer my immediate question. But now I have follow-up. It used to be true that the best practice ensure data file integrity was to use Quicken to make a record-by-record copy of the data file and then validate that copy. What is the best practice now that that is no longer practical? I don't want to wait until corruption becomes so bad that I notice the problem and then have to go far back in time for a restorable backup.
