Help! - SCP Automated Backup file using Password

What about backing up to ftp and using something similar to the following:

!/bin/sh -x

tmsh save /sys ucs /var/tmp/LTM_backup
export a=`date +"%y%m%d"`
export aa=$HOSTNAME.$a.ucs
export b=/var/tmp/$aa
mv /var/tmp/LTM_backup.ucs $b

tar -cf /var/tmp/certs.tar /config/ssl
export ff=$HOSTNAME.$a.certs.tar
export f=/var/tmp/$ff
mv /var/tmp/certs.tar $f

export c=$HOSTNAME.$a.crontab
export cc=/var/tmp/$c
cp /etc/crontab $cc

export MName=1.1.1.1
export Log=/var/tmp/log.bigip

export UserName=SomeUserName
export UserPassword=SomePassWord

export Machine1f2=$aa
export Machine1f3=$c
export Machine1f4=$ff

ftp -nvd ${MName} 14 <<-END 1>&2 > ${Log}
user ${UserName} ${UserPassword}
bin
passive
put ${b} ${Machine1f2}
put ${cc} ${Machine1f3}
put ${f} ${Machine1f4}
quit
END
rm -f ${b}
rm -f ${cc}
rm -f ${f}
RTN_CODE=$?

exit $RTN_CODE

You can then configure a crontab entry and schedule backups for whenever suits you.
