59 Mail Housekeeper Redundancy Group

The Mail Housekeeper Redundancy Group target is a grouping of Housekeeper agent monitored targets that have identical configuration, characteristics, and functionality. While a single Housekeeper server instance is vulnerable to the failure of its host or system, a redundant group of Housekeepers continues to function despite the loss of a Housekeeper server instance, hiding any such failure from clients, and allowing other Housekeeper server instances in the group to service the requests.
