What are your current practices for: Archiving data and managing time versions Managing geodatabase versions Transfer mechanisms for data to regional entities? to off-site storage for disaster recovery? Archiving project files and finished products What rights issues exist with regard to putting county and city data into an archive? What would you like this project to do?
