+=item MEMCACHED_BEHAVIOR_NUMBER_OF_REPLICAS
+
+If you just want "a poor mans HA", you may specify the numbers of
+replicas libmemcached should store of each item (on different servers).
+This replication does not dedicate certain memcached servers to store the
+replicas in, but instead it will store the replicas together with all of the
+other objects (on the 'n' next servers specified in your server list).
