By correctly backing up the .NET Framework, you can make sure that applications that are built by using the .NET Framework continue to function correctly when you restore the files.

The system writer in Windows Vista provides the list of files to the backup software. The system writer is part of the Volume Shadow Copy API in Windows Vista. For more information about how to use the Volume Shadow Copy API, visit the following MSDN Web site:
