Duplicity backup script for S3 fails on CentOS 5 - duplicity

Question

Hi I have not been able to setup backup to S3 using this guide:
http://www.cenolan.com/2008/12/how-to-incremental-daily-backups-amazon-s3-duplicity/
I get this error when I run the script:
Command line error: Expected 2 args, got 0
Enter 'duplicity --help' for help screen.
The duplicity log file:
2013-08-07_17:43:20: ... backing up filesystem
./duplicity-backup: line 60: --include=/home: No such file or directory
My script is like this:
!/bin/bash
# Set up some variables for logging
LOGFILE="/var/log/backup.log"
DAILYLOGFILE="/var/log/backup.daily.log"
HOST='hostname'
DATE=`date +%Y-%m-%d`
MAILADDR="user#domain.com"
# Clear the old daily log file
cat /dev/null > ${DAILYLOGFILE}
# Trace function for logging, don't change this
trace () {
stamp=`date +%Y-%m-%d_%H:%M:%S`
echo "$stamp: $*" >> ${DAILYLOGFILE}
}
# Export some ENV variables so you don't have to type anything
export AWS_ACCESS_KEY_ID="xxxxx"
export AWS_SECRET_ACCESS_KEY="xxx"
export PASSPHRASE="xx"
# Your GPG key
GPG_KEY=xxxx
# How long to keep backups for
OLDER_THAN="1M"
# The source of your backup
SOURCE=/
# The destination
# Note that the bucket need not exist
# but does need to be unique amongst all
# Amazon S3 users. So, choose wisely.
DEST="s3+http://xxxx"
FULL=
if [ $(date +%d) -eq 1 ]; then
FULL=full
fi;
trace "Backup for local filesystem started"
trace "... removing old backups"
duplicity remove-older-than ${OLDER_THAN} ${DEST} >> ${DAILYLOGFILE} 2>&1
trace "... backing up filesystem"
duplicity \
${FULL} \
--encrypt-key=${GPG_KEY} \
--sign-key=${GPG_KEY} \
--volsize=250 \
# --include=/vhosts \
# --include=/etc \
--include=/home \
--include=/root \
--exclude=/** \
${SOURCE} ${DEST} >> ${DAILYLOGFILE} 2>&1
trace "Backup for local filesystem complete"
trace "------------------------------------"
# Send the daily log file by email
cat "$DAILYLOGFILE" | mail -s "Duplicity Backup Log for $HOST - $DATE" $MAILADDR
# Append the daily log file to the main log file
cat "$DAILYLOGFILE" >> $LOGFILE
# Reset the ENV variables. Don't need them sitting around
export AWS_ACCESS_KEY_ID=
export AWS_SECRET_ACCESS_KEY=
export PASSPHRASE=
Does anyone see what is wrong?

You should remove commented lines from script execution. From:
duplicity \
${FULL} \
--encrypt-key=${GPG_KEY} \
--sign-key=${GPG_KEY} \
--volsize=250 \
# --include=/vhosts \
# --include=/etc \
--include=/home \
--include=/root \
--exclude=/** \
${SOURCE} ${DEST} >> ${DAILYLOGFILE} 2>&1
to
duplicity \
${FULL} \
--encrypt-key=${GPG_KEY} \
--sign-key=${GPG_KEY} \
--volsize=250 \
--include=/home \
--include=/root \
--exclude=/** \
${SOURCE} ${DEST} >> ${DAILYLOGFILE} 2>&1
