Abstract
Backup system and method that can determine a backup destination in consideration of disaster are provided. There are provided: a data acquisition unit 110 that acquires disaster information, network information, and node information; a replication group construction unit 130 that generates, based on the disaster information, and the like, replication group information including association information between a first node that stores original data and one or more second nodes that are candidates for backup destination of the original data, and saves the replication group information in a storage unit 120; a replication destination node calculation unit 140 that, when executing backup of the original data, calculates the second node as backup destination from the replication group; and a replication processing unit 230 that replicates and stores the original data into the storage of the second node.
