was having the same issue. in the pg_log/enterprisedb-2016-02-08_031257.log i see this "Client IP address resolved to "<actual_hostname>", forward lookup not checked." So, i modified pg_hba.conf file to this: host replication postgres <actual_hostname> trust and then ran the backup command like this; pg_basebackup -D /mnt/gfs/pgdata/base_backup -h <actual_hostname> -Ft -z -xlog-method=f -l backup4DB-02 -P -v that worked. hope this helps the next son of a bitch with the same issue -- View this message in context: http://postgresql.nabble.com/A-local-replication-entry-tp5824819p5886429.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
