Script no CRON não roda completamente

Bom dia pessoal, tenho um script de backup que roda normalmente manualmente, porém quando jogo no cron, o mesmo começa e para logo após ter backupeado somente 30M por exemplo, abaixo segue o script de backup e o cron e os arquivos.

#!/bin/bash
fecha=`date +"%d-%m-%Y"`

# Backup and gzip the directory
sudo tar -cvzpf /var/backups/backup/backup-$fecha.tgz --same-owner --exclude="/export/*" --exclude="/var/backups/backup/*" --exclude="/var/backups/backup/error.log" --exclude="/proc/*" --exclude="/media/*" --exclude="/dev/*" --exclude="/mnt/*" --exclude="/sys/*" --exclude="/tmp/*" / 2>/var/backups/backup/error.log
# Rotate the logs, delete older than 7 days
find /var/backups/backup/ -mtime +7 -exec rm {} \;

# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.

SHELL=/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user command

Nao me pergunte pq mas a unica maneira que funciona eh desviando para tty

Ex
0 6 * * * root Script > /dev/tty1

E não eh que funciona mesmo!!! :laugh:
