   Another method, easy to do, is to rsync the entire tree to a folder with   
   a timestamp in the name, hardlinking to the previous backup. This is   
   actually an incremental backup. The last backup contains only the new or   
   modified files, and hard links to the intact files from yesterday copy.   
   The last folder appears to contain everything.   
      
      
   Basically:   
      
   rsync $OPTIONS --link-dest=$PREVIOUS $WHAT $CURRENT
