Abstract
Machines, systems and methods for recovering data objects in a distributed data storage system, the method comprising storing one or more replicas of a first data object on one or more clusters in one or more data centers connected over a data communications network; recording health information about said one or more replicas, wherein the health information comprises data about availability of a replica to participate in a restoration process; calculating a query-priority for the first data object; querying, based on the calculated query-priority, the health information for the one or more replicas to determine which of the one or more replicas is available for restoration of the object data; calculating a restoration-priority for the first data object based on the health information for the one or more replicas; and restoring the first data object from the one or more of the available replicas, based on the calculated restoration-priority.
