Remarks
The SharePoint Foundation VSS Writer service (sometimes called the SPF Writer service or the SPF-VSS Writer) is a Windows Service that is installed with SharePoint Foundation. It enables SharePoint Foundation administrators to ensure that their SharePoint Foundation non-database components are protected by Volume Shadow Service.
Use this class as a base class to create informational objects that SPVssDiscoveryHelper will pass to the SharePoint VSS Writer service.
You will also need to create a VSS writer for your custom non-database component.
Custom database components only need to be registered in the configuration database for the farm. There is a built-in VSS writer in the SharePoint VSS Writer service that will include them along with the native SharePoint Foundation databases in the shadow copies. Accordingly, you do not need to create a VSS writer for them, nor do you need to derive classes from SPVssDiscoveryHelper or SPVssComponentDefinition for database components.
