Having just set up a system with 240GB of disk space as a testbed system,
the production system may be larger, I'd be interested to know what the
high-end backup options are on x86 hardware and Linux/FreeBSD, but that's
only part of the problem here.
You can't (or shouldn't) back up the data files in pgsql if the database
is running.
