Abstract: A storage system with high availability is provided. The storage system is designed to be provided with: a generation unit that generates information of an association volume which is associated with each volume, on the basis of information of each volume created at each of a plurality of storage devices designated from two or more sites; and an instruction unit that issues an instruction to each storage device, at which each volume is created, to connect each volume associated with the association volume and a compute node which operates a container, on the basis of a request for activation of the container for which the information of the association volume generated by the generation unit is designated.

Abstract: A security system includes a backup acquisition unit configured to store given information indicating states of backup data together with backup images generated from the backup data for each backup generation; and a determination unit configured to generate, when a predetermined timing comes, determination information for determining whether there is an abnormality in the stored backup data, based on a predetermined determination rule and the given information for each backup generation, and to output the generated determination information.
