Examples
The following shows the SPBackupRestoreObjectCollection class being used in a method that will ensure that the component name submitted by a user uniquely identifies a single component to be the top of the tree of components that will be processed by a backup or restore operation. For the full example and a detailed discussion of it, see How to: Programmatically Back Up Content.

{
