In ArcGIS Pro, the Share Locator option does not have the functionality to disable data copying when sharing locators as hosted services to ArcGIS Server. By default, ArcGIS Server allows publishers to package and copy service source data to ArcGIS Server machines during the publishing process. However, ArcGIS Server administrators may find it necessary to disable the automatic data copying functionality when publishers initiate the publishing process for various reasons. These reasons include performance optimization and enhancing efficiency, particularly in scenarios where substantial datasets are accumulated within the ArcGIS Server machines. As a workaround, refer to ArcGIS Server: Disable automatic data copying when publishing to ArcGIS Server for instructions to block data from being automatically copied to ArcGIS Server when publishing.
