Backup script til mysql virker ikke helt

Jeg bruger dette script på min side til at lave en backup af min mysql database, men jeg får en fejl hvis jeg vælger at den skal slette filen på serveren "Hedder i script $remove_file". Er der en der kan se hvad fejlen er da jeg ikke er den store haj til programmering

Den fejl jeg får når den er færdig, men filen er stadig på serveren, Jeg har prøvet at chmod mappen til 777 men det hjælper ikke noget.
