I use this script, called "backsize", run from a cron job to monitor my backups 
and
seeing their size -

--8<---------------cut here---------------start------------->8---
#!/bin/bash
# to get back-up directories size

file=~/cron/backshow

if ! >$file; then
        echo "Error: Access issue while creating file";
        exit 1;
fi

function ComposeFile() { #arg1 friendly_name; arg2 dir
        size_kb=`(du -s $2 | awk '{print $1}') 2>/dev/null`;
        if [ -n "${size_kb}" ]; then
                #calculate into gb with 2 floting ponts controlled by scale
                gb=`echo "scale=2; $size_kb / 1024 / 1024" | bc -l`;
                #if you need wider columns change 25 into i.e. 35
                printf '%-20s %-20s\n' "$1" "${gb}gb" >> $file
        fi
}
# ComposeFile doesnt_exist /dummy
ComposeFile obnam-home /media/boudiccas/back1/obnam-home
ComposeFile music /media/boudiccas/back1/obnam-back4

sed -i '$!N;s/\n/ /' $file
cat $file

exit 0;
--8<---------------cut here---------------end--------------->8---

This then emails me the results when it runs -

--8<---------------cut here---------------start------------->8---

Subject: Cron <boudiccas@london> /home/boudiccas/bin/backsize
To: boudiccas@localhost

obnam-home           406.64gb             obnam-back4                250.72gb 
--8<---------------cut here---------------end--------------->8---

Does it help?
