backup.sh

So here is my problem: i have created an backup script for my root server, it is saving several things at once and suddently i didn't get an reporting email from my crontab anymore.
as far as i could track it down the script is working and cron is sending several mails for other jobs it is performing, so i'm a bit in a mess. :-( please help me out, here is my script:
