title: Real-Time File Mirroring in Linux to a NAS
body: <p>Can anyone tell how I might best mirror selected files and folders to a NAS, (Network Addrssable Storage) box from a Linux workstation in real-time?</p>
  
  <p>These are very large files, (> 50GB) and are being continually modified, so I would only like to change those portions of the files that have been changed, added or deleted.</p>
  
  <p>FYI: These files are actually Virtual Box virtual hard disk (VDI) files.</p>
