Finally got the answer!!! Create shell script ftpmirror.sh

#!/bin/bash 
path = /local-dir-path
lftp -e "mirror -R $path /$path" -u username,password ftp-server-ip
Path = local directory which we want to copy into ftp server
username = ftp server user name
password = ftp server password
ftp-server-ip = IP address of ftp server
If lftp package is not installed the installed it using yum.
