I see.

So something like the following, once a week:

    $ time nice -n 19 \
            ionice -c 3  \
             du --one-file-system --human --bytes --separate-dirs / \
              | bzip2 > /tmp/du-disk-scan.txt.bz2
    real        44m25.142s
    user        0m8.333s
    sys 0m31.502s

    $ ls -lh /tmp/du-disk-scan.txt.bz2
    -rw-r--r-- 1 root root 1.2M Feb  3 23:13 /tmp/du-disk-scan.txt.bz2

Then keep few previous runs in /var/cache/diskusage/[date].txt.bz2 ,
and if need be, compare them with your script?
