I do backups semi-manually:
use select pg_start_backup('some-name') (in psql logged in a postres)
then start a tar of /var/lib/pgsql/data/, to stdout and pipe this to
tar on another server using ssh
then finally select pg_stop_backup()
e.g. my two scripts (backup.sh calls back1.sh
[root@www pgsql]# cat back1.sh
#/bin/bash
cd /var/lib/pgsql
ssh lead touch /var/lib/postgresql/backups/start_backup
tar zcf - data |ssh lead "cat > /var/lib/postgresql/backups/20091223.tgz"
echo "DONE"
[root@www pgsql]# cat backup.sh
#!/bin/bash
cd /var/lib/pgsql
./back1.sh > backups/backup.log 2>&1 </dev/null &
[root@www pgsql]#
