Information processing apparatus and computer-readable storage medium storing information processing program

A non-transitory computer-readable storage medium storing an information processing program that causes a computer to execute a process comprising:

• registering, when performing a first operation on a first data group of a plurality of data groups stored in a memory, each of which has been classified as a unit of data transfer to an external storage apparatus, first operation information corresponding to the first data group in transfer control information in which at least one item of operation information each corresponding to any one of the plurality of data groups stored in a memory is registered;
• temporarily storing, when extracting the first data group as a transfer target, the first operation information corresponding to the first data group as stored information and transferring the first data group to the external storage apparatus;
• updating, when performing a second operation on the first data group while the first data group is being transferred to the external storage apparatus, the first operation information registered in the transfer control information;
• comparing, when completing the transferring of the first data group to the external storage apparatus, the first operation information registered in the transfer control information with the stored information;
• and
• retransferring, when the first operation information and the stored information do not match, the first data group corresponding to the first operation information to the external storage apparatus.
