Syntax
HRESULT SetBackupOptions(

[in] LPCWSTR wszLogicalPath,
[in] LPCWSTR wszComponentName,

);
Parameters
[in] writerId

The logical path can be NULL.
There are no restrictions on the characters that can appear in a non-NULL logical path.

The string containing the name cannot be NULL and should contain the same component name as was used when the component was added to the backup set using IVssBackupComponents::AddComponent.
