Single call in .bashrc starting two daemon processes

I am using CentOS 6.6 and would like /OtagoHarbour/executables/inotifydropboxcopy to start as a daemon when I boot the computer and log in. I put the following in ~/.bashrc

 # User specific aliases and functions
 /OtagoHarbour/executables/inotifydropboxcopy &

When I boot up the computer and enter

ps aux | grep inotifydropboxcopy

I get

500       1859  0.0  0.0   3268   732 ?        S    16:11   0:00 /OtagoHarbour/executables/inotifydropboxcopy
500       2175  0.0  0.0   3268   728 pts/0    S    16:11   0:00 /OtagoHarbour/executables/inotifydropboxcopy
500       2843  0.0  0.0   4356   728 pts/0    S+   17:12   0:00 grep inotifydropboxcopy

When I comment out /OtagoHarbour/executables/inotifydropboxcopy & in .bashrc and restart the computer

ps aux | grep inotifydropboxcopy

returns

500       2843  0.0  0.0   4356   728 pts/0    S+   17:12   0:00 grep inotifydropboxcopy

Can someone tell me how to start exactly 1 /OtagoHarbour/executables/inotifydropboxcopy daemon process when I boot up the ocmputer and log in?
