kron backup config

Hi ,
 
Here is what I have to achieve. I ahve a server in my network in which I am
running a tftp server. All my network switches should backup their config to
this server every 24 hrs. How can I achieve this through kron? Can anyone
provide me a good link for this please?
 
I am using the following config but i am not sure how to give the path to the
tftp server inside kron.
kron occurrence SCHEDULE in 2:12:0 recurring
 policy-list SAVECONFIG
!
kron policy-list SAVECONFIG
 cli write
 !
kron policy-list BACKUP
 cli show run | redirect
