HOW TO
Rather than save a local copy of a downloaded feature service to a file geodatabase, save the local copy to a local enterprise/workgroup geodatabase for continuous syncing. This is similar to setting up a replica.
There is an option to do this using the Distributed Geodatabase toolbar options. Adjust the setting to point to the database connection. This must be a database connection, not a database server connection. If it is a database server connection, right-click the database and select Save Connection to create a database connection from the database server connection.
For more information on database server connections, refer to the following ArcGIS Web Help page: Database server connections.
