Look up the contabs entry in the manual; basically, there is already a
daemon called 'cron' that executes commands at scheduled times.  This
daemon reads files in /usr/spool/cron/crontabs that contain the commands
in question.  For example, to do the backup, you would put an entry in
/usr/spool/cron/crontabs/root that looks like:

0 2 * * * /usr/local/bin/do_backup

Again, it's all in the manual.
