It is wholly possible that NTFS could be like OpenBSD's filesystem, in

NTFS does journalling, but quite different from XFS - they record the state of a data structure before and after a metadata change - which makes it possible to unwind transactions. There is a book on it, but I am not sure it is still in
print.
