Programmatically copy in-use files

Question

In my C# code I want to be able to use some Shadow Copy mechanism in order to copy files that are being used by another process.

I've seen that solutions exist on the web, in enterprise or command line tools. But could it be done programmatically in order to mimic a simple file copy?

Answer 1

It appears that alphavss does what you want. The sample file VssBackup.cs here seems to do exactly what you want.

This class encapsulates some simple VSS logic. Its goal is to allow a user to backup a single file from a shadow copy (presumably because that file is otherwise unavailable on its home volume).
