Data required by the task to successfully run but that has not yet been registered with the data store will be copied to the ArcGIS server during the publishing process.
- Do nothing. The source data will be copied to the ArcGIS server.
- Register the folder or enterprise geodatabase that your data resides in with the server's data store. When a folder or enterprise geodatabase is registered with the data store, the publishing process will not copy the data to the server.
Registering a data source with the server ensures the server has access to the data the task uses. If a data source is not registered with the server, the data used by the task you are publishing will automatically be copied to the server.
