A
B
Have
been
going
every
day
for
almost
a
year,
lee
1
has
actually
been
done.
It's
a
wrongfully
distributed
record
and
per
year.
It
seems
like
very
little,
but
I
think
it's
as
disruptive
as
it
was
in
the
early
90s.
When
you
connecting
two
machines,
it
was
difficult
to
see
that
it
was
going
to
become
the
internet.
It
was
going
to
become
today
something
that
is
everywhere
in
society.
I
think
that
today
the
fact
that
we
can
have
a
self-healing
network
disk
is
something
that
will
transform
all
uses.
What
exactly
does
that
mean?
B
There
are
times
you
can
go
to
the
store
and
then
buy
three
discs
in
one
box,
and
the
salesman
says
when
there
is
a
disc
that
actually
breaks
them,
two
others
they
can
take
over
it's
a
bit
of
self-repair,
it's
even
better.
If
you
manage
to
do
that,
not
in
a
box
but
with
several
machines,
and
but
for
that
you
need
software,
which
is
relatively
sophisticated
and
csf.
So
it's
is
in
fact
you
give
him
machines,
which
are,
for
example,
in
your
office.
B
You
have
your
colleagues,
you
have
ten
colleagues
each,
they
have
a
machine,
they
will
say
well,
I
give
a
disk
portion
of
my
seif
machine
and
all
of
that,
suddenly
it
creates
a
disk
available
for
everyone
which
is
1
distributed
when
there
is
someone
who
is
a
his
machine,
in
fact,
this
f
he
will
not
lose
data
because
he
makes
copies.
He
realizes
that
there
is
a
current
machine
had
left
for
the
weekend
at
is
a
term
in
chinhoyi
de
la
and
turned
on.
So
suddenly
the
data
on
it
is
no
longer
available.
B
His
daughter
realizes
this,
and
then
he
will
make
copies
again
for
sure
that
you
lose.
You
lose
nothing.
I,
think
that
there
it's
sacef,
and
today
it's
free
software.
It's
unstable
say
that
we
can
use
it
for
should
not
lose
data.
There
are
people
at
the
University
of
Nantes,
for
example,
who
use
it
massively
on
three
sites
to
manage
to
store
the
data
that
are
used
by
ten
thousand
students,
and
thousands
of
employees.
There
are
also
much
more
modest
uses
such
as
I
went
to
see
this
week
at
inra.
He
uses
that
to
store
data.
B
A
Well,
it's
times
the
first
time,
I
knew
that
it
was
through
openstack
late
in
a
logic
there
at
the
beginning,
we
understand
the
interest,
but
today
it's
true:
it's
not
only
cloud
cia.
No
longer
that's
what
these
big
platforms
are
for
these
multi-
platforms,
c
c
koi,
the
ecosystem
of
cf
a
little
and
the
idea
of
.
The
project
are
historical.
B
The
history,
in
fact
it
started
in
2006.
Today
we
are
all
the
same
in
2013.
It's
been
a
very
long
time
to
mature
and
storage
systems
generally
take
a
very
long
time
to
mature,
because
before
you
manage
to
entrust
them
with
the
data,
you
must
be
sure
that
they
will
not
losing
them
takes
a
really
long
time.
So,
in
fact,
it's
something
that
has
developed
in
the
free
ecosystem
for
very
long
years
and
which
today
is
standard
in
all
distributions,
because
it's,
for
example,
integrated
into
the
kernel
linux
since
I
believe
the
2
6
38.
B
Also
in
the
clad
side,
it
is
very
attractive
for
people
who
make
1
of
the
club
of
cloud
computing
because
it
makes
it
possible
to
completely
decouple
the
management
of
storage
from
the
provision
of
the
storage,
but
on
a
much
more
modest
scale
for
the
individual.
For
me,
for
example,
I
have
three
machines
somewhere.
I
want
to
stop
thinking
about
6.
B
This
machine
breaks
I
have
to
take
the
back
up,
which
is
on
such
other
machine
I
uses
it's
simply
because
suddenly,
when
I
have
a
machine
that
break
game,
replace
it
but
later,
but
I
continue
to
access
my
data.
So
what
it
is
there
is
this
very
ambitious
side
of
cloud
computing
and
the
very
modest
side
of
the
personal
use
very.
A
B
A
site
which
sf
points
as
in
you
find
the
project
there
is.
It
is
a
project
which
is
very
open
to
the
very
welcoming
community.
There
is
a
level
of
technicality
which
is
important
on
the
deepest
parts,
but
there
are
also
the
peripheral
parts
or
even
if
we
are
just
proofreading
documentation.
If
we
do,
we
say
to
ourselves
like
I
use
such
a
free
software
distribution.
I
would
like
it
to
work
better.
We
can
intervene
and
therefore
contribute
very.
