I need a lightweight Windows desktop application that keeps local Microsoft SQL Server databases in step with a master copy stored in Dropbox. Each time we export a fresh SQL dump (or .bak) into a dedicated Dropbox folder, the app should: • Detect the newest file, download it, and restore/overwrite the user’s local database. • Record and display the exact date-and-time of the last successful sync on the main screen.
