Abstract

A first information processing apparatus receives file information from a second information processing apparatus when the second information processing apparatus is switched to a power saving state. When the first information processing apparatus receives a file information acquisition request, which is directed to the second information processing apparatus from another apparatus, the file information that has been received from the second information processing apparatus is sent to the other apparatus. The first information processing apparatus acquires by proxy a file that is to be stored in the second information processing apparatus and sends the file acquired by proxy to the second information processing apparatus when the second information processing apparatus is restored to the normal power state.

Claims

1. An information processing system including a first information processing apparatus and a second information processing apparatus capable of communicating with the first information processing apparatus,

the first information processing apparatus comprising:

a receiving unit configured to receive, from an external device via a network, a request for storing a new file into the second information processing apparatus when the second information processing apparatus is in a power saving state;

a first storage unit configured to store the file of the request received by the receiving unit, without returning the second information processing apparatus from the power saving state;

a transmitting unit configured to transmit a response for the request to the external device; and

a transferring unit configured to transfer the file stored in the first storage unit to the second information processing apparatus when the second information processing apparatus is returned from the power saving state after the transmitting unit transmits the response,

the second information processing apparatus comprising;

a second storage unit; and

a control unit configured to control such that the file transferred from the first information processing apparatus is stored in the second storage unit,

wherein the power saving state is a state in which power is not supplied to at least the second storage unit.

4. The information processing system according to claim 1, wherein the power saving state is a state in which power supply at least to a storage device of the second information processing apparatus is cut off.

5. The information processing system according to claim 1, further comprising a file information receiving unit configured to receive file information indicative of a file attribute that is stored in the second information processing apparatus, from the second information processing apparatus.

6. The information processing system according to claim 5, wherein the file information receiving unit received the file information when the second information processing apparatus is switched to the power saving state.

7. The information processing system according to claim 5, wherein the file information includes at least information indicative any one of a file name of the file, a creator of the file, and a created date and time of the file.

8. The information processing system according to claim 5, further comprising an update unit configured to update the file information, based on the request received by the receiving unit.

2. An information processing apparatus comprising:

a receiving unit configured to receive, from an external device, a request for storing a new file into another information processing apparatus when the other information processing apparatus is in a power saving state, wherein the power saving state is a state in which power is not supplied to at least a second storage unit included in a second information processing apparatus;

a first storage unit configured to store the file of the request received by the receiving unit, without returning the other information processing apparatus from the power saving state;

a transmitting unit configured to transmit a response for the request to the external device; and

a transferring unit configured to transfer the file stored in the first storage unit to the second storage unit of the second information processing apparatus when the second information processing apparatus is returned from the power saving state after the transmitting unit transmits the response.

9. The information processing apparatus according to claim 2, wherein the power saving state is a state in which power supply at least to a storage device of the second information processing apparatus is cut off.

10. The information processing apparatus according to claim 2, further comprising a file information receiving unit configured to receive file information indicative of a file attribute that is stored in the second information processing apparatus, from the second information processing apparatus.

11. The information processing apparatus according to claim 10, wherein the file information receiving unit received the file information when the second information processing apparatus is switched to the power saving state.

12. The information processing apparatus according to claim 10, wherein the file information includes at least information indicative any one of a file name of the file, a creator of the file, and a created date and time of the file.

13. The information processing apparatus according to claim 10 further comprising an update unit configured to update the file information, based on the request received by the receiving unit.

3. An information processing method for an information processing system including a first information processing apparatus and a second information processing apparatus capable of communicating with the first information processing apparatus, the method comprising:

causing the first information processing apparatus to receive, from an external device via a network, a request for storing a new file into the second information processing apparatus when the second information processing apparatus is in a power saving state;

causing the first information processing apparatus to store the file of the received request in a first storage unit, without returning the second information processing apparatus from the power saving state;

causing the first information processing apparatus to transmit a response for the received request to the external device;

causing the first information processing apparatus to transfer the stored file from the first storage unit of the first information processing apparatus to a second storage unit of the second information processing apparatus when the second information processing apparatus is returned from the power saving state after the response is transmitted; and

controlling the second information processing apparatus to store in the second storage unit, the file transferred from the first information processing apparatus,

wherein the power saving state is a state in which power is not supplied to at least the second storage unit.
