We
...
have
...
just
...
migrated
...
our
...
calendars
...
from
...
MeetingMaker
...
to
...
...
Apps
...
for
...
Education.
...
This
...
cloud
...
service
...
is
...
of
...
course
...
very
...
cool
...
and
...
all
...
that,
...
but
...
I
...
would
...
still
...
like
...
to
...
have
...
an
...
off-cloud
...
backup.
...
There
...
are
...
several
...
commercial
...
applications
...
that
...
you
...
can,
...
but
...
I
...
wanted
...
something
...
simple
...
that
...
can
...
be
...
scheduled
...
from
...
CRON.
...
A
...
useful
...
script
...
is
...
the
...
one
...
from
...
...
...
...
.
This script uses WWW:Mechanize
...
to
...
login
...
in
...
to
...
...
Calendar
...
and
...
download
...
a
...
ZIP
...
copy
...
of
...
all
...
the
...
calendars.
...
If
...
you
...
make
...
sure
...
the
...
user
...
account
...
is
...
an
...
administrative
...
one,
...
and
...
is
...
subscribed
...
to
...
all
...
your
...
users
...
calendars,
...
this
...
will
...
make
...
a
...
ZIP
...
file
...
containing
...
all
...
calendars.
...
Unfortunately
...
that
...
did
...
not
...
work
...
straight
...
away,
...
because
...
our
...
'regular'
...
users
...
use
...
...
...
...
...
...
...
.
So the URLs in Matthew's
...
script
...
did
...
work.
...
Moreover,
...
the
...
federated
...
stuff
...
makes
...
'mechanizing'
...
it
...
alot
...
more
...
complex.
...
The
...
good
...
thing
...
is
...
you
...
can
...
have
...
non-federated
...
accounts
...
as
...
well,
...
you'll
...
need
...
to
...
use
...
https://www.google.com/a/cpanel/domain.com
...
to
...
access
...
the
...
control
...
panel.
...
From
...
there,
...
the
...
admin
...
can
...
also
...
make
...
backups
...
of
...
calendars.
...
I
...
adjusted
...
the
...
original
...
script
...
to
...
use
...
that
...
specific
...
administrative
...
page.
...
Also,
...
I
...
made
...
the
...
script
...
read
...
in
...
a
...
password
...
file,
...
instead
...
of
...
giving
...
sensitive
...
information
...
on
...
the
...
command
...
line,
...
which
...
makes
...
it
...
show
...
up
...
in
...
the
...
process
...
list.
...
This
...
might
...
be
...
an
...
issue,
...
since
...
backing
...
up
...
several
...
large
...
calendars
...
takes
...
a
...
while.
