Thanks for pointing that out i thought i had changed that. How could i go about catching errors to be output in the email. Also, is it not necessary to have the .sh extension on my bash/cron script? Here is the updated script without all the output.

Code:
#!/bin/bash

cd ~/mysub.example.com

#/************************ EDIT VARIABLES ************************/
projectName="mysub_demo"
backupDir="/home/username/_backups"
#/************************ //EDIT VARIABLES **********************/

fileName=$projectName-$(date +"%Y-%m-%d-%H%M")
host=$(grep DB_HOST "wp-config.php" |cut -d "'" -f 4)
username=$(grep DB_USER "wp-config.php" | cut -d "'" -f 4)
password=$(grep DB_PASSWORD "wp-config.php" | cut -d "'" -f 4)
dbName=$(grep DB_NAME "wp-config.php" |cut -d "'" -f 4)

# Backup DB
mysqldump -h "$host" -u "$username" -p"$password" "$dbName" | gzip > $fileName.sql.gz

# Backup files
tar -zcf $fileName.tar.gz * .htaccess
rm -f $fileName.sql.gz

# Move to backup directory
mkdir -p $backupDir;
mv $fileName.tar.gz $backupDir

# Keep last 30 Backups
find $backupDir -type f -mtime +30 -exec rm {} +

Do I need to be wrapping each step in some kind of if else to do error checking? Something like the following?

Code:
if [ "$?" = "0" ]; then
    #some command
else
    echo "Error. Couldn't do some command!" 1>&2
    exit 1
fi

Sorry for the additional post but this is a work in progress and keeps changing. This is the latest... trying to do a bit of checking and handling here... really dont know what I'm doing though. Could use some advice.

Code:
#!/bin/bash

cd ~/mysub.example.com || exit

#/************************ EDIT VARIABLES ************************/
projectName="mysub_demo"
backupDir="/home/username/_backups"
#/************************ //EDIT VARIABLES **********************/

fileName=$projectName-$(date +"%Y-%m-%d-%H%M")
host=$(grep DB_HOST "wp-config.php" |cut -d "'" -f 4)
username=$(grep DB_USER "wp-config.php" | cut -d "'" -f 4)
password=$(grep DB_PASSWORD "wp-config.php" | cut -d "'" -f 4)
dbName=$(grep DB_NAME "wp-config.php" |cut -d "'" -f 4)

# Backup DB
mysqldump -h "$host" -u "$username" -p"$password" "$dbName" | gzip > $fileName.sql.gz

# Backup files
tar -zcf "$fileName.tar.gz" * .htaccess &&
    rm -f "$fileName.sql.gz"

# Move to backup directory
mkdir -p "$backupDir";
mv "$fileName.tar.gz" "$backupDir"

# Keep last 30 Backups
find "$backupDir" -type f -mtime +30 -exec rm {} +
