Samba 2.0.6 for OpenVMS.

Tracking the bit to meaningfully give the state is operating system 
dependent.  And may even depend on optional backup products installed.

OpenVMS has the last recorded backup date as an attribute for the file, 
so SAMBA 2.0.6 for OpenVMS has it implemented as a O.S. specific hack to 
report the backup state of the file.

At this time, SAMBA 2.0.6 for OpenVMS does not allow the client to 
manipulate the backup date, as there is no public A.P.I. to do it.

A VFS layer may be a way to do this.
