Ymmv. Your du may match client usage, or not. Are files excluded
from the backup? Are duplicate files being found by backuppc (and of
course "deduplicated")? If files of significant size or quantity are
excluded or deduplicated your du will be missing that much.

i pledge allegiance to the earth
and all that lives upon her
and the delicate balance in which it stands
one planet
unending spirit
harmonious
with deep respect for all

what if mother earth herself is the modern day christ?
what of those who ignore her pleading, on the belief
that their next life is in rapture? will history place them
along with judas, pilate, herod, and the executioners?
will their god be more lenient?
everything we need, to destroy, or protect, the entire earth,
is available now. it's in our hands. what shall we do?
considering what we know about how our choices affect the world
of our grandchildren, how can we be of service to one another
to come into better integrity with what we know?
