[ADMIN] Redundant

[Paulo Henrique Baptista de Oliveira]

        Hi all Postgresql users and admin,
        I have a site with Perl+PostgreSQL and I want to build a backup 
        server w/ a up-to-date copy of server's db
        I already know how to know that the server is up. I want to maintain the
        two servers up2date.
        What is the best method to do this?
        pg_dump + diff in a cron hour script.
        Thanks,         Paulo Henrique
