If you want a consistent database (you *REALLY* do), pg_dump is the correct tool.

Hi, v8.4.20 This is what the current backup script uses: /usr/bin/psql -U postgres -c "SELECT pg_start_backup('Incrementalbackup',true);" cp -r /var/lib/pgsql/data/* $dumpdir/data/ /usr/bin/psql -U postgres template1 -c "SELECT pg_stop_backup();" Should it use rsync or pg_dump instead?
