I am trying to use a backup script that will backup my sql database and website files.
I am running Ubuntu 12.04 32 bit version and zPanel.

Also what are these variables:

MYSQL="$()"

MYSQLDUMP="$()"

GZIP="$()"

I assume the first one is DB name.

Here is the script:

#!/bin/sh

#----------------------------------------------------------------

# Daily Backup Routine - Backup and Sync to Dropbox

# This script creates a backup using today's date, then deleted

# any backups made 3 days ago. If run every day it will ensure

# you have a week's worth of backups of your MySQL databases and

# zPanel web directories. 

#

# Uses whatever Dropbox account is running on the server.

#

# Written by Richard Ferreira for the backup of zPanel websites.

# Contact me - richard[at]beetle001.com

#----------------------------------------------------------------

#

# Before we get started, we should set some parameters. We'll need these for later.

# The webserver's datafiles:

WEBDIR="/var/zpanel/hostdata/"

# Where do we want the backup to go?  (SET THIS - IT'S A TEMP FOLDER)

BACKUP="/root/backup-temp"

# Where is our dropbox folder? (SET THIS TO YOUR ABSOLUTE BACKUP PATH)

DROPBOX="/root/Dropbox/Backups

# What do we want our date to look like?

NOW=$(date +"%d-%m-%Y")

# We need to know the date 3 days ago to purge any backups that were made 3 days ago.

# This ensures we don't keep unnecessarily old backups.

# It doesn't matter if it skips one every now and then - we'll just have to check manually from time to time.

# If you want to keep more days backups, change the "3 days ago" to "x days ago"

DAYSAGO=$(date --date="3 days ago" +"%d-%m-%Y")

# What should our file backup look like?

WEBFILE="webdirs-full-$NOW.tar.gz"

# Our MySQL Login information and some paths (we'll use 'which' to make sure we get them):

SQLUSER="root"

# Don't forget to change the root password here!

SQLPASS="xxxxxxxxxxxx"

SQLHOST="localhost"

MYSQL="$(db-name)"

MYSQLDUMP="$(db-name)"

GZIP="$(.gz)"

#

# Let's just, for sanity's sake, make sure our temp backup folder exists.

mkdir $BACKUP

# DON'T EDIT ANYTHING BELOW THIS LINE

#----------------------------------------------------------------

# Now let's start!

# Let's get the databases that we want to backup.

DBS="$($MYSQL -u $SQLUSER -h $SQLHOST -p$SQLPASS -Bse 'show databases')"

# Now let's dump them to .sql files and put them in our backup directory.

for db in $DBS

do

FILE=$BACKUP/mysql-$db.$NOW.gz

$MYSQLDUMP -u $SQLUSER -h $SQLHOST -p$SQLPASS $db | $GZIP -9 > $FILE

done

#

# Let's shove the whole webserver directory into a tarball and throw that in with the sql files:

tar -zcvf /root/backup/$WEBFILE $WEBDIR

# That's all done - we should put the backups on Copy by putting them into our Copy folder.

# First let's make a folder for today.

mkdir $DROPBOX/$NOW

# Copy our backups into it.

cp -R $BACKUP/* $DROPBOX/Asterix/$NOW

# We can delete the backup we made 3 days ago from Copy now.

rm -rf $DROPBOX/$DAYSAGO

# And clear out the temporary director for next time.

rm $BACKUP/*

# Job well done!

# Have a beer and relax!

Here is my problem:
When I try to run the script I get this error:
./backup.sh: 66: ./backup.sh: Syntax error: Unterminated quoted string

If anyone could help me with this would appreciate it a lot!
