 	  Normally, the environemt is stored in a single location.  By
 	  selecting this option, you can then define where to hold a redundant
 	  copy of the environment data, so that there is a valid backup copy in
 	  case there is a power failure during a "saveenv" operation.
+	  Also this config changes the binary environment structure handling
+	  which is used by env import/export commands which are independent of
+	  storing variables to redundant location on a non volatile device.
