Duplicate files on Restore from Backup

When I restore files from a backup, when Foldershare is turned back on it
duplicates all of the files adding "- <machinename>" to the duplicate files.
The files should be exactly the same except perhaps for a datestamp somewhere
(I haven't been able to track down if anything changed).

Just restoring using Foldershare isn't practical since I'm often restoring a
bunch of data which isn't on Foldershare (Music and Video directories in
addition to My Documents).

Is there a way to tell Foldershare to leave files alone if they are exactly
the same except for being restored?
