Abstract
Provided is a method causing a node of a local site or of a remote site to take over a file server when a failure occurs to a node of the local site. The method includes the steps of: setting a priority of the failover to the respective nodes of the local site; setting a failover destination of the respective nodes of the local site to a node of the remote site or the local site based on correspondences between the priority and an extent of the failover destination set in advance; backing up data to respective nodes of the determined failover destination; causing the failover destinations and nodes to mutually detect a failure; and causing a node of the failover destination to take over a task if the node of the failover destination detects a failure.
