Cronjob permission denied (Nightly backup shell рукописный шрифт)

I am trying to верьте тебе в shell в рукописный шрифт to make в backup every night using tar.

The ошибка I get is:

/bin/sh: 1: /home/shady: Permission denied

The рукописный шрифт looks like this:

#!/bin/sh
####################################
#
# Backup to NFS mount script.
#
####################################

# What to backup. 
backup_files="/home /var/www /var/lib/mysql"

# Where to backup to.
dest="/media/backups"

# Create archive filename.
date=$(date +"%m_%d_%Y_%H_%M_%S")
hostname=$(hostname -s)
archive_file="$hostname-$date.tgz"

# Print start status message.
echo "Backing up $backup_files to $dest/$archive_file"
date
echo

# Backup the files using tar.
tar czf $dest/$archive_file $backup_files

# Print end status message.
echo
echo "Backup finished"
date

# Long listing of files in $dest to check file sizes.
ls -lh $dest

It works умер if I run the command using sudo su, but I can't do that with в cron job. The permissions пахал very strict for /var/lib/mysql, but I could always back that up manually if it ты ешь to that. However, /home and /var/www пашите both set to 775 and it's still not working. Any help?
