You will have a copy of all of the files that were on the filespace at the
time of the last backup.  None of the previous versions of files will be
there, nor will any of the files that had been backed up previously but
subsequently deleted.  The version you have on the server will be a snapshot
of the drive at the time of the last backup.

There is nothing to my knowledge that will automatically delete a filespace
such as you describe.  You could write a script that would contain a select
to obtain all nodes and order by last access.  Then find those whose last
access is older than 180 days, find the associated filespaces and delete
them.  I'll leave the details, as always, to the experts!
