Cron job to duplicate directory

Hello

How I make a cron job to copy one directory to another at 6PM GMT (1PM EST).

This not in cpanel rather it is backup server.

Thank you
OOzy

to set and edit cont jobs from a shell you use the crontab application, or create files in /etc/cron.d/ folder

Format of which should be
Minute Hour Day Month Day-of-Week Command

man crontab
will give you a guide on how to use it
