That's not the to cron to do that. You must put in your script some flags. For example if you using rsnapshot (in the ports) he put a lock file in /var/run (or what's ever you want) and don't start if the script find this file. When the script is end the file is erase. Something like if_the_lock_file_exit : exit 1 else touch lock_file my_script rm lock_file fi.
