Abstract

An information processing system including multiple memory devices and a processor configured to select one node group associated with a time point included in a time period between a current time point and a time point before a predetermined time including the current time point among multiple node groups each associated with one of multiple time points, and store the N pieces of distributed data one to each of N memory devices included in the selected node group. The information processing system carries out a restoring process on at least one of the multiple node groups, and if the restoring results in failure, carries out the restoring process on a second node group associated with a time point before a time point associated with the first node group that causes the failure among the plurality of node groups.
