Remarks

The Windows SharePoint Services VSS Writer service (sometimes called the WSS Writer service or the WSS-VSS Writer) is a Windows Service that is installed with Windows SharePoint Services 3.0. It enables Windows SharePoint Services 3.0 administrators to ensure that their Windows SharePoint Services 3.0 non-datatabase components are protected by Volume Shadow Service.

Use this class as a base class to create informational objects that SPVssDiscoveryHelper will pass to the Windows SharePoint Services 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 Windows SharePoint Services VSS Writer service that will include them along with the native [wssnoversshort] 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.
