→Hard Links
'''Advantages:''' If only one hard link remains (even if original file has been removed), the '''data in that hard linked file is NOT lost'''. The data in hard linked files are '''automatically updated''' when original file are updated.
'''Disadvantages:''' Hard links '''take-up extra space''',<br>you '''cannot hard link directories''', <br>and you '''cannot hard link files from other Unix/Linux servers''' (since the inode number may already be used by the other Unix/Linux server).
