  First, a user having authority to execute backup processing inputs an instruction to execute backup processing from the operation display unit 103. Note that the connection state of the HDD 180 in this state is as shown in FIG.

  Then, the instruction from the operation display unit 103 is transmitted to the CPU 101, and the CPU 101 that has received this instruction switches the information processing apparatus 100 to the backup processing execution mode (steps S201 and S211 in FIG. 2).

  Here, the CPU 101 displays a message for urging replacement of the HDD 180 on the operation display unit 103 (step S212 in FIG. 2). Here, for example, a message as shown in FIG. 4A is displayed, and from the state as shown in FIG. 3A to the state as shown in FIG. 3B, that is, data connected to the first slot. The HDD 180-1 for use is removed and replaced with the HDD 180'-1 for saving instead.

  Here, the CPU 101 confirms the HDD ID and the like, and continues to display the message on the operation display unit 103 until the evacuation HDD 180′-1 is connected to the first slot as shown in FIG. Step S213 in FIG. A pilot lamp such as an LED may be turned on in the vicinity of the slot of the HDD to be replaced.

  Here, when it is detected from the ID of the HDD 180′-1 that the evacuation HDD 180′-1 is connected to the first slot as shown in FIG. 3B (in step S213 in FIG. 2). YES), the CPU 101 reads the data stored in the HDD 180-2 in the second slot and copies it as backup data to the evacuation HDD 180'-1 connected to the first slot, thereby performing the backup process. This is executed (step S214 in FIG. 2).

  Here, when the CPU 101 finishes copying all the data stored in the HDD 180-2 in the second slot as backup data to the save HDD 180'-1 connected to the first slot, the ID of the HDD 180 is stored. By confirming whether or not the backup processing has been executed for all the HDDs 180 connected to the information processing apparatus 100 from the beginning (step S215 in FIG. 2).

  At this point, since the backup processing of the data stored in the HDD 180-1 in the first slot has not been completed, the CPU 101 displays a message as shown in FIG. From the state shown in FIG. 3B, the state shown in FIG. 3C, that is, the evacuation HDD 180′-1 connected to the first slot is removed and replaced with the data HDD 180-1. The data HDD 180-2 connected to the two slots is removed and replaced with the evacuation HDD 180′-2 (step S212 in FIG. 2).

  Here, the CPU 101 checks the ID of the HDD, and continues to display a message on the operation display unit 103 until each HDD is connected as shown in FIG. 3C (step S213 in FIG. 2). A pilot lamp such as an LED may be turned on in the vicinity of the slot of the HDD to be replaced.

  Here, the fact that the data HDD 180-1 is connected to the first slot and the evacuation HDD 180'-2 is connected to the second slot as shown in FIG. If it is detected (YES in step S213 in FIG. 2), the CPU 101 reads out the data stored in the HDD 180-1 in the first slot, and stores it in the save HDD 180′-2 connected to the second slot. By copying as backup data, backup processing is executed (step S214 in FIG. 2).

  Here, when the CPU 101 finishes copying all the data stored in the HDD 180-1 of the first slot as backup data to the save HDD 180'-2 connected to the second slot, the ID of the HDD 180 is stored. By confirming whether or not the backup processing has been executed for all the HDDs 180 connected to the information processing apparatus 100 from the beginning (step S215 in FIG. 2).

  At this point, since the backup processing of the data stored in the HDD 180-1 in the first slot and the backup processing of the data stored in the HDD 180-2 in the second slot have been completed, the CPU 101 A message as shown in FIG. 4C is displayed on the operation display unit 103. From the state as shown in FIG. 3C, the state as shown in FIG. 3D, that is, the retreat connected to the second slot. The HDD 180′-2 for use is removed and replaced with the data HDD 180-2, and the same initial state as in FIG. 3A is restored (step S217 in FIG. 2).

  Thereafter, the CPU 101 switches the operation mode from the backup process execution mode to the normal operation mode, and returns the information processing apparatus 100 to the normal operation (step S202 in FIG. 2).

  As described above, in the backup processing execution mode, any of the plurality of HDDs 180 that have been used for data storage up to that time by the information processing apparatus 100 is removed, and the save HDD 180 ′ is connected, so that the save The CPU 101 that detected the replacement of the HDD 180 ′ stores the data stored in the data HDD 180 connected to the information processing apparatus in the saving HDD 180 ′ as backup data. This operation is repeated alternately.

  Therefore, in this information processing apparatus 100, it is necessary to provide extra space dedicated for evacuation in all respects such as installation space (slot), interface, controller, power supply capacity, signal cable, heat dissipation, etc., for the HDD 180 'for evacuation. Disappears. As a result, it is possible to efficiently perform backup of the HDD 180 that stores data without requiring an extra configuration dedicated to saving.

  When there is an operation request other than the backup processing of the information processing apparatus 100 during the above-described backup processing execution mode, the CPU 101 causes the information processing apparatus 100 to operate in an operation mode that does not use the HDD 180. Control each part. As a result, the backup process being executed is not interrupted, and a part of the operation of the information processing apparatus 100 can be performed as much as possible without using the HDD 180. Therefore, efficient backup processing and information can be performed. Compatibility with the operation of the processing apparatus 100 can be realized.

  In addition, when there is an operation request other than the backup process of the information processing apparatus 100 during the above-described backup process execution mode, the CPU 101 does not permit any operation other than the backup process being executed by the information processing apparatus 100. You may do it. As a result, the backup process being executed is not interrupted, and operations other than the backup process as the information processing apparatus 100 are not permitted and the backup process has priority, so the backup process is executed reliably. It becomes possible.

  In the above case, the HDD 180-1 connected to the first slot during normal operation, the HDD 180′-1 installed in the first slot during backup processing, and the HDD 180-2 connected to the second slot during normal processing. In order to prevent the HDD 180′-2 installed in the second slot from being installed in a different slot during the backup process, it is desirable to perform color-coded display and character display in the vicinity of each HDD and the slot of the information processing apparatus 100.

  FIG. 5 shows a display with characters and marks. HDDs 100m-1 and 100m-2 attached near the slots of the information processing apparatus 100 are attached, and the character display 180m- is displayed on the HDD 180-1. 1. The character display 180m-2 is attached to the HDD 180-2.

  In the above case, the HDD 180-1 connected to the first slot during normal operation, the HDD 180′-1 installed in the first slot during backup processing, and the HDD 180-2 connected to the second slot during normal operation. It is also desirable that each HDD and the slot of the information processing apparatus 100 be provided with a connector shape, a slot shape, unevenness, etc. so that the HDD 180′-2 attached to the second slot during the backup process is not attached to a different slot.

  The example shown in FIG. 6 is an external view of the inside of the slot in the information processing apparatus 100 as viewed from the outside, and has different protrusions 100p-1 and 100p-2 for each slot. The HDD 180-1 connected to the first slot and the HDD 180′-1 attached to the first slot during the backup process are provided with a recess corresponding to the protrusion 100p-1 of the first slot. The HDD 180-2 connected to the second slot during normal time and the HDD 180′-2 attached to the second slot during backup processing are provided with a recess corresponding to the protrusion 100p-2 of the second slot. It shall be. This makes it impossible to mount the HDD 180 in the wrong slot.

  In the example shown in FIG. 7, the HDD 180-1 connected to the first slot, the HDD 180′-1 installed in the first slot during the backup process, and the HDD 180-2 connected to the second slot during the backup process are backed up. It is assumed that the HDD 180′-2 that is installed in the second slot during processing is configured in a different shape. This makes it impossible to mount the HDD 180 in the wrong slot.

  In the example shown in FIG. 8, the HDD 180-1 connected to the first slot, the HDD 180'-1 installed in the first slot during backup processing, and the HDD 180-2 connected to the second slot during normal backup It is assumed that the HDD 180′-2 that is installed in the second slot during processing is configured in a different shape. Further, different projections 100p-1 and 100p-2 are provided in each slot. The HDD 180-1 connected to the first slot and the HDD 180′-1 attached to the first slot during the backup process are provided with a recess corresponding to the protrusion 100p-1 of the first slot. The HDD 180-2 connected to the second slot during normal time and the HDD 180′-2 attached to the second slot during backup processing are provided with a recess corresponding to the protrusion 100p-2 of the second slot. It shall be. This makes it impossible to mount the HDD 180 in the wrong slot.

Moreover, you may comprise in the state which combined suitably either of FIGS. 5-8. This further makes it impossible to mount the HDD 180 in the wrong slot.

The operation of the restoration process of the information processing apparatus 100 according to the present embodiment will be described below with reference to the flowchart of FIG.

  First, a user having the authority to execute the restoration process inputs an instruction to execute the restoration process from the operation display unit 103. The connection state of the HDD 180 in this state is as shown in FIG.

  Then, the instruction from the operation display unit 103 is transmitted to the CPU 101, and the CPU 101 that has received this instruction switches the information processing apparatus 100 to the restoration processing execution mode (steps S201 and S221 in FIG. 2).

  Here, the CPU 101 displays a message for prompting the replacement of the HDD 180 on the operation display unit 103 (step S222 in FIG. 2). Here, for example, a message as shown in FIG. 10A is displayed, and from the state as shown in FIG. 9A to the state as shown in FIG. 9B, that is, data connected to the first slot. The HDD 180-1 is removed and replaced with a recorded evacuation HDD 180'-1.

  Here, the CPU 101 checks the HDD ID and the like, and continues to display a message on the operation display unit 103 until the recorded save HDD 180′-1 is connected to the first slot as shown in FIG. 9B.

  Here, when it is detected from the ID of the HDD 180′-1 that the recorded save HDD 180′-1 is connected to the first slot as shown in FIG. 9B (step S223 in FIG. 2). The CPU 101 reads out the backup data stored in the recorded save HDD 180′-1 connected to the first slot and copies it to the HDD 180-2 in the second slot, thereby performing the restoration process. This is executed (step S224 in FIG. 2).

  Here, the CPU 101 confirms the ID of the HDD 180 when all the data stored in the recorded save HDD 180′-1 connected to the first slot has been copied to the HDD 180-2 of the second slot. By doing this, it is confirmed whether restoration processing has been executed for all the HDDs 180 connected to the information processing apparatus 100 from the beginning (step S225 in FIG. 2).

At this time, since the restoration processing of the data stored in the recorded saving HDD 180′-2 is not completed, the CPU 101 displays a message as shown in FIG.

Copying to −1 executes the restoration process (step S224 in FIG. 2).

  Here, the CPU 101 confirms the ID of the HDD 180 when all the data stored in the recorded save HDD 180′-2 connected to the second slot has been copied to the HDD 180-1 of the first slot. Thus, it is confirmed whether restoration processing has been executed for all the HDDs 180 connected to the information processing apparatus 100 from the beginning (step S225 in FIG. 2).

  At this point, since the restoration process for the first slot and the restoration process for the second slot are completed, the CPU 101 displays a message as shown in FIG. 10C on the operation display unit 103, and FIG. 9), the state shown in FIG. 9D, that is, the recorded save HDD 180′-2 connected to the second slot is removed and replaced with the data HDD 180-2. 9 (a) is returned to the initial state (step S227 in FIG. 2).

  After that, the CPU 101 switches the operation mode from the restoration process execution mode to the normal operation mode, and returns the information processing apparatus 100 to the normal operation (step S202 in FIG. 2).

  As described above, in the restoration processing execution mode, any one of the plurality of HDDs 180 that have been used for data storage until then by the information processing apparatus 100 is removed, and the recorded saving HDD 180 ′ is connected, so that the saving is performed. The CPU 101 that has detected the replacement of the HDD for HDD 180 ′ stores the data stored in the recorded saving HDD 180 ′ connected to the information processing apparatus in the data HDD 180. This operation is repeated alternately.

  Therefore, in this information processing apparatus 100, it is necessary to provide extra space dedicated for evacuation in all respects such as installation space (slot), interface, controller, power supply capacity, signal cable, heat dissipation, etc., for the HDD 180 'for evacuation. Disappears. As a result, it is possible to efficiently execute the restoration process of the HDD 180 that saves data without requiring an extra configuration dedicated to saving.

  When there is an operation request other than the restoration process of the information processing apparatus 100 during the above-described restoration process execution mode, the CPU 101 causes the information processing apparatus 100 to operate in an operation mode that does not use the HDD 180.
