Ntfs Shadow Volume redirect on write

I am developing an application that require to read an ntfs partition while other program are writing on it and i need to assure consistency of the data i read.

A solution i found is having Volume Shadows as redirect on write. but VSS use copy on write by default.

my question is:

• Is it possible to parameter VSS to use redirect on write?
  • if not, is there some available providers that can do it?
  • or how technical/complex would it be to write my own Volume Shadow provider?
