    - copy flash tftp command is used to take a back up of the image on IOS.

    - Sometime there is a chance that the router loses power or loses connection during the IOS image transfer (copy from or to server) which may cause the router to have no working IOS image to boot up from.

    - When such incident happens then first you take the back up of the IOS image to server before deleting working IOS image off the router flash memory.
