how to run inotifywait background

[mixo]

Hello.
I want to run Inotifywait background.
I use:
nohup inotifywait -rm --timefmt "%Y %B %d %H:%M" --format "%T =-= %e %w%f" -e create,delete,move /somefile1 >> /somefile2
then type ctl+Z and bg and it runs background.
But when I type such a way:
nohup inotifywait -rm --timefmt "%Y %B %d %H:%M" --format "%T =-= %e %w%f" -e create,delete,move /somefile1 >> /somefile2 &
and bg, it doesn't work.It moves background and stops,doesn't run.
How can I run inotifywait background with & symbol?

Try this:

nohup inotifywait -rm --timefmt "%Y %B %d %H:%M" --format "%T =-= %e %w%f" -e create,delete,move /somefile1 >> /somefile2 &> /dev/null &

thanks falko.

It sends log to /dev/null.
So I use:

nohup inotifywait -rm --timefmt "%Y %B %d %H:%M" --format "%T =-= %e %w%f" -e create,delete,move /somefile1 > /dev/null &> /somefile2 &

Can anybody explain why it needs two redirection, ">" ?
