I was responding to MBR.
Versioning filesystems are not designed to allow you to see the state of the filesystem at any arbitrary point in the past.  Aside from any other issues, I do not believe they have the ability to remove a file from the "current view", but leave all the generations of that file available for constructing a "veiw in the past".
