Abstract

A server manages first time at which a configuration of a client apparatus is changed, while associating the first time with the client apparatus. The server obtains information indicating second time at which previous synchronization processing of a setting value is performed with the client apparatus. In the case where the second time is after the first time, the server sends, in response to a reception of a request for a setting value from the client, the client apparatus a setting value which is updated after the second time and type of which corresponds to the changed configuration of the client apparatus. In the case where the second time is before the first time, the server sends, in response to a reception of a request for a setting value from the client, the client apparatus setting information including a setting value which is not updated after the second time.

in a case where the second time obtained by the obtaining unit is before the first time, send, in response to a reception of a request for a setting value from the client, the client apparatus setting information including a setting value which is not updated after the second time and type of which corresponds to the changed configuration of the client apparatus.

2. The information processing apparatus according to claim 1, further comprising:

a first receiving unit configured to receive notification of update of a setting value from the client apparatus; and

a setting unit configured to perform set-up such that, in a case where the setting value included in the notification received by the first receiving unit is a setting value indicating change in the configuration of the client apparatus, the setting information including the setting value which is not updated after the second time and type of which corresponds to the changed configuration of the client apparatus is sent to the client apparatus; and

a second receiving unit configured to receive a synchronization request from the client apparatus, wherein

in the case where the second receiving unit receives the synchronization request, the sending unit sends the client apparatus, having sent the synchronization request received by the second receiving unit, the setting information based on the set-up by the setting unit.

3. The information processing apparatus according to claim 2, wherein, in the case where the set-up is not performed in the setting unit, the sending unit sends the client apparatus, having sent the synchronization request received by the second receiving unit, a setting value which is updated after the second time and type of which corresponds to the changed configuration of the client apparatus.

4. The information processing apparatus according to claim 1, further comprising:

a first receiving unit configured to receive notification of update of a setting value from the client apparatus; and

a setting unit configured to perform set-up such that, in a case where the setting value included in the notification received by the first receiving unit is a setting value indicating change in the configuration of the client apparatus, a setting value related to the change in the configuration of the client apparatus is sent to the client apparatus as synchronization target data; and

a second receiving unit configured to receive a synchronization request from the client apparatus, wherein

in the case where the second receiving unit receives the synchronization request, the sending unit sends the client apparatus, having sent the synchronization request received by the second receiving unit, the synchronization target data based on the set-up of the setting unit.

5. The information processing apparatus according to claim 1, wherein the obtaining unit obtains the second time at which in response to a synchronization request including identification information on a user of the client apparatus, the previous synchronization processing is performed for a setting value associated with the user.

6. The information processing apparatus according to claim 1, wherein the sending unit sends the client apparatus the setting value excluding a setting value related to a configuration disabled in the client apparatus from a synchronization target.

7. The information processing apparatus according to claim 6, wherein whether the predetermined configuration is enabled or disabled is determined based on at least one of a setting value indicating presence or absence of a license for a device in the client apparatus, a setting value indicating presence or absence of a function of a device in the client apparatus, a setting value indicating a state of the license, and a setting value indicating a state of the function.

8. An information processing apparatus configured to function as a client to a server apparatus, comprising:

a notifying unit configured to notify the server apparatus of first time at which a configuration of the information processing apparatus is changed;

a sending unit configured to send the server apparatus information indicating second time at which previous synchronization processing of a setting value is performed with the server apparatus; and

a receiving unit configured to

in a case where the second time is after the first time, receive a setting value updated after the second time, from the server apparatus according to the configuration of the information processing apparatus, and

in a case where the second time is before the first time, receive setting information including a setting value which is not updated after the second time and type of which corresponds to the changed configuration of the information processing apparatus, from the server apparatus.

9. The information processing apparatus according to claim 8, further comprising a setting unit configured to set information indicating that the configuration of the information processing apparatus is changed, wherein

in the case where the information is set by the setting unit, the sending unit sends the server apparatus a synchronization request including a request to send back the setting information including the setting value which is not updated after the second time and type of which corresponds to the changed configuration of the information processing apparatus.

10. The information processing apparatus according to claim 8, further comprising a setting unit configured to set information indicating that the configuration of the information processing apparatus is changed, wherein

in the case where the information is set by the setting unit, the sending unit sends the server apparatus a synchronization request not including the second time.

11. The information processing apparatus according to claim 10, wherein, in the case where the information is not set by the setting unit, the sending unit sends the server apparatus a synchronization request including the second time.

12. A data synchronization method in an information processing apparatus including a managing unit configured to manage first time at which a configuration of a client apparatus connected to the information processing apparatus is changed, while associating the first time with the client apparatus, the method comprising:
