Example: Prevent data copying at publish time—Develop and extend

This script blocks data from being copied to the server at publish time. The option to block data copying became available at ArcGIS 10.1 Service Pack 1.

When you publish an item such as a map document to ArcGIS Server, the server checks all the data sources referenced in the document to determine if they are registered with ArcGIS Server. Data from any unregistered sources is copied to the server by default and placed in the server directories. As a server administrator, you may want to block the data copying in order to force data registration and prevent datasets from accumulating on the server.

You only need to run this script once on your server to block all data copying.
