Hello,
you could run the below EEM script. If you configure a command alias to run the applet, all you would have to do is type "crt" at the exec prompt to run the operation. You could even schedule the script to run at certain intervals.
event manager applet COPY_RUN_TFTP
event none
action 1.0 cli command "enable"
action 2.0 cli command "copy running-config tftp://10.1.2.210/Cisco.cfg" pattern "confirm"
action 3.0 cli command "y"
action 4.0 cli command "end"
alias exec crt event manager run COPY_RUN_TFTP
