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