2 is a flowchart illustrating a process of setting a shared area for data synchronization in a dedicated server according to an exemplary embodiment of the present invention and performing synchronization using the shared area.

2, an administrator of a specific SMB client 100, that is, an administrator of the dedicated server 102 selects a specific folder in the folder hierarchy supported by the file system, And generates the shared area information using the information on the subfolders of the specific folder (S200). The generated shared area information is provided to the data synchronization and service providing device 150 so that the shared area managing part 154 of the data synchronizing and service providing device 150 uses the provided shared area information to access the cloud storage 170 To allocate storage space for data synchronization to the specific SMB client 100.

Then, the dedicated server 102 of the specific SMB client 100 determines whether there is a request for accessing data in the cloud storage 170 from any member terminal (not shown) (S202). That is, the member terminal requests authentication using the user's ID and password information to access the shared folder, and then determines whether there is an access request for the shared folder set by the specific SMB client 100 (S202).

As a result of the determination in S202, if there is an access request, the dedicated server 102 generates a notification message to notify that there is an access request and transmits the notification message to the manager of the specific SMB client 100 (S204). For example, the dedicated server 102 may display a notification message on a screen of an administrator terminal (not shown), or may transmit a notification message to an administrator's mobile communication terminal or an administrator's e-mail.

Then, the dedicated server 102 extracts data requested by the member terminal from the shared folder and provides the data (S206).

Thereafter, when there is a data service termination request from the member terminal (S208), the dedicated server 102 determines whether the data in the shared folder has been changed (S210). Here, the data change may mean that the data in the storage space is deleted, edited, added, and so on.

As a result of the determination in S210, when the data in the shared folder is changed, the dedicated server 102 may perform data synchronization by providing the changed data to the data synchronization and service providing apparatus 150 (S212). In other words, the data synchronization unit 156 of the data synchronization and service providing apparatus 150 receives the changed data in the shared folder from the dedicated server 102 and updates the storage space allocated to the cloud storage 170, And perform synchronization between the storage 104 of the storage device 102 and the cloud storage 170.

If an error occurs during data provision in S206, that is, when an error occurs while the dedicated server 102 is reading data from the shared folder, the dedicated server 102 generates an error in the data synchronization and service providing apparatus 150 The data stored in the temporary storage space can be read and supplied to the member terminal as well as the data stored in the temporary storage space can be used to store the data in the shared folder in the storage 104 The stored data can be recovered.

In the embodiment of the present invention, the data synchronization is performed when the data in the shared folder is changed and the service is terminated. However, the rules set by the administrator of the dedicated server 102, Data synchronization can be performed by rules set by the administrator. That is, when the manager of the dedicated server 102 sets a predetermined time interval, data changes in the shared folder of the storage 104 are provided to the data synchronization and service providing apparatus 150 at predetermined time intervals, A data change in the storage space of the cloud storage 170 may be provided from the providing device 150. [

In addition, data synchronization can be performed based on an administrator request or data synchronization of the dedicated server 102 and an administrator request of the service providing apparatus 150.

According to the embodiment of the present invention, a shared folder is set in the storage 104 of the dedicated server 102, a storage space corresponding to the shared folder is allocated to the cloud storage 170, Data synchronization can be performed using data changes, thereby eliminating data loss due to anomalies in the storage 104, and accessing the cloud storage 170 and using the data from outside.

3 is a flowchart illustrating a process of synchronizing data synchronization and service providing apparatus according to an embodiment of the present invention.

3, the administrator of the specific SMB client 100, that is, the administrator of the dedicated server 102 selects a specific folder in the folder hierarchy supported by the file system, And generates the shared area information using the information on the subfolders of the specific folder. The generated shared area information is provided to the data synchronization and service providing device 150 so that the shared area managing part 154 of the data synchronizing and service providing device 150 uses the provided shared area information to access the cloud storage 170 To the specific SMB client 100 (S300). At this time, the authentication management unit 160 receives the user authentication information and the manager information for the members in the specific SMB client 100, and stores the received information in the storage unit 162.

Thereafter, the access processing unit 152 of the data synchronization and service providing apparatus 150 determines whether there is a request for access to the storage space from the user terminal 180 connected through the wired / wireless communication networks 120 and 190 (S302). In other words, the user terminal 180 accesses the data synchronization and service providing apparatus 150 using the user's ID and password to determine whether to access the data stored in the storage space.

If it is determined in step S302 that there is an access request, the access processing unit 152 of the service providing apparatus 150 generates a notification message using the information of the user requesting access and transmits the notification message to the manager using the manager information (S304). In other words, the notification message may be generated in the form of an SMS message and transmitted to the mobile communication terminal of the management site or by the manager's e-mail.

Then, the access processing unit 152 extracts the data requested by the user terminal 180 requesting access from the storage space, and transmits the data to the user terminal 180. At this time, the access processing unit 152 determines whether an error occurs while reading data in the storage space (S306, S308). If it is determined in step S308 that an error has occurred, the access processing unit 152 requests the error processing unit 158 for error processing. Accordingly, the error processing unit 158 provides a message to the user terminal 180 that the data can not be provided due to the occurrence of the error, and then requests the dedicated server 102 of the specific SMB client 100 to send the error- And the data of the storage space is recovered (S310, S312).

On the other hand, if it is determined in operation S308 that no error is generated, the access processing unit 152 reads data from the storage space and provides the data to the user terminal 180 (S314).

If the user terminal 180 requests data service termination (S316), that is, when the user terminal 180 completes the data synchronization and the connection from the service providing apparatus 150, the data synchronization unit 156 transmits the data to the cloud storage It is determined whether data in the storage space of the storage unit 170 has been changed (S318). Here, the data change may mean that the data in the storage space is deleted, edited, added, and so on.

As a result of the determination in S318, when the data in the storage space is changed, the data synchronization unit 156 may perform data synchronization by providing the changed data to the dedicated server 102 (S320). In other words, the data synchronization unit 156 of the data synchronization and service providing apparatus 150 transmits the changed data in the storage space to the dedicated server 102 to store the data stored in the shared folder in the storage 104 of the dedicated server 102 The synchronization between the storage 104 of the dedicated server 102 and the cloud storage 170 can be performed.
