I have two database files I'd like to read-only sync. 1. Microsoft Access file about 95 meg. Mostly static, but at key hours (5pm to 7pm) may have up to 45 record updates/creation per minute. Only two users update the system. 2. Btrieve database about 19 meg. Very static. May have up to 5 record updates/creation per minute from 8am to 10am. Only one user updates the system. Both databases run our business, so I'm hesitant to implement if this would corrupt them. Thanks!
