Hum...I'm not sure I really understand what you doing.

Maybe I'm doing everything wrong but this is what I did :

    t=0      SELECT pg_start_backup('label');
        rsync /pgsql backup_server:/
        SELECT pg_stop_backup();

    t> 1     cron with rsync /WAL backup_server:

but after some time the /WAL become big. So is it a solution to
stop the database, delete everything in /WAL and begin a new cycle (t=0 select etc...) ?
