Storage apparatus and recording medium storing backup program

A storage apparatus comprising:

• a determination circuit configured to determine a path between one of a plurality of backup power sources and one of a plurality of backup target circuits, each of the plurality of backup target circuits including a memory based on configuration information, state information of the storage apparatus, and setting information of performance request for the storage apparatus;
• a plurality of switches arranged between the plurality of backup target circuits and the plurality of backup power sources;
• and
• a control circuit configured to control the switches to couple the backup target circuit to the backup power source via the path determined by the determination circuit,
• each of a plurality of storage control apparatuses that control the storage apparatus includes the backup target circuit, and
• when an early use of a cache memory is set as the performance request setting information and the amount of power of the backup power source is equal to or greater than an amount of power of backing up one storage apparatus, the determination circuit determines the path so that one of the plurality of storage control apparatuses is coupled to the backup power source.
