Can I exclude files from a shadow copy to save space?
VSS is designed to create shadow copies of entire volumes. Temporary files, such as paging files, are automatically omitted from shadow copies to save space. To exclude specific files from shadow copies, use the following registry key: FilesNotToSnapshot.
