Controlling apparatus, and controlling method

A non-transitory computer-readable storage medium storing a controlling program causing a computer connected to a plurality of physical devices in which respective virtual machines are operated and a process device which is connected to the plurality of physical devices with a plurality of routes and in which a plurality of duplication process virtual machines for executing a duplication process of duplicating data used by the plurality of virtual machines to a memory device different from the plurality of the physical devices are operated, to execute:

• acquiring loads of the plurality of routes and percentages of completion of the duplication process executed by the plurality of duplication process virtual machines;
• when the route is selected based on a used band and incompletion of the duplication process using the selected route within a regulated time is detected based on the percentage of completion, moving any of the duplication process virtual machines for performing the duplication process using the selected route to any of the plurality of physical devices from the process device;
• and
• when incompletion of the duplication process using the selected route within a regulated time is detected based on the percentage of completion, specifying any duplication process virtual machines for performing the duplication process using the selected route, based on a correspondence relation between the plurality of routes and the duplication process virtual machines for performing the duplication process using the routes,
• wherein the physical device at a movement destination is determined with the condition that completion of the duplication process executed by the duplication process virtual machine to be moved, when the duplication process virtual machine as a movement target is moved, is expected based on the percentage of completion.
