# Backup this cluster
#
+# This define causes the cluster to be registered on the backupservers.
+#
+# Furthermore, if this cluster is managed with postgresql::server and
+# do_role and do_hba are set, we create the role and modify the pg_hba.conf file.
+#
+# Since postgresql::server only supports a single cluster per host, we are moving
+# towards our own postgres::cluster, and this define also exports a hba rule for
+# those (regardless of the do_hba setting). If the cluster is managed with
+# postgres::cluster and has its manage_hba option set, this will then cause the
+# backup hosts to be allowed to replacate.
+#
+# Regarless of how the cluster is managed, firewall rules are set up to allow
+# access from the backup hosts.
