Next, the operation will be described with reference to FIG. FIG. 3 shows a setting procedure of the data backup method according to the present invention. The mobile phone user uses the mobile phone 10 in advance to set the data backup method. For the data backup method item, set the backup target data type (S
10), presence / absence of data compression (S11), backup trigger setting (S12), and the like. The setting of the data type to be backed up (S10) is performed by individually specifying the data extension or by specifying a specific application and collectively specifying a data group used by the application. A specific keyword in the file name (for example, the one containing the character string "BackUp")
It may be set by specifying. Presence or absence of data compression S
At 11, it is designated whether or not to perform data compression when the backup data is stored in the mobile phone 10. By compressing and storing the data, the substantial capacity of the storage unit can be expanded. Backup trigger setting (S1
In 2), a trigger for starting backup processing to the backup server 123 is set. The trigger may be mainly activated from the mobile phone 10 side or may be activated from the backup server 123 side. Sequential backup (immediate execution when specified by the user), storage size specification (executed when the total size of backup files stored in the terminal exceeds a certain value) , Specific operation designation (power on, etc., executed immediately after performing a specific operation). When starting from the backup server 123 side, there are a timer start (automatic start at a specific time), a retry start when backup processing fails, and the like. The setting information is stored in the storage unit 34.
Stored in. When starting from the backup server 123 side, the setting information is registered in the backup server 123.

The backup data target data types include telephone directory data, electronic mail address data, WWW server address data, and the like, and it is desirable that these can be identified by the extension. Then, of these various data, the data to be backed up can be set. It is also possible to prepare an appropriate initial setting so that the user can use the data backup method without setting it. For example, in the initial setting, only the telephone directory data may be backed up so that the setting can be changed according to the intention of the user. As a result, the user can automatically create a backup file without making any settings, and the convenience can be further improved.

Next, FIG. 4 shows a flowchart when the backup data is created. The user performs a data operation (S1) on the mobile phone 10 and saves the corresponding file,
When updated (S2), the control unit 35 of the mobile phone 10 checks whether or not the corresponding file is a backup target file by comparing it with preset information (S2).

When a different file is edited, the backup file is newly created each time, and when the same file is edited again, the backup file is overwritten and updated with a new backup file and stored. When storing data, create a profile separately from the backup file body. When creating backup data, the profile is used to manage information such as whether the same file has been re-edited or has already been backed up.

When a file of the same type is edited, the backup file may be saved with a different file name without being overwritten and updated each time. For example, it is desirable to add a serial number of 001, 002, and 003 to the header or footer of the file name in the order of saving. Further, it may be saved as a different file for each type of data. This makes it possible to handle various types of data.

Next, FIG. 5 shows a sequence diagram when backup is carried out in response to a request from the backup server 123 side. When a backup trigger occurs on the backup server 123 side according to the backup trigger setting S12 of FIG. 3, the backup server 123 notifies the mobile phone 10 of a backup start request. The mobile phone 10 that has received the notification confirms that backup data is not currently being created, and returns a backup start response. After that, the data is transferred to the backup server 123 side. Depending on the size of the backup data, the data may be appropriately divided and transferred. Further, the handshake method at the time of data transfer is arbitrary, and an Ack (confirmation signal) from the server side may be waited for in divided packet units.

When the transfer of the data to be transferred to the backup server 123 is completed, the mobile phone 10 side sends a backup end notification. The backup server that has received the end notification message closes the file in the server, ends the processing, and transfers the completion notification to the mobile phone 10. By including the file name and size of the transferred backup file in the end notification / completion notification as data, the reliability of the sequence can be increased. Therefore, the data can be reliably transmitted.

When the mobile phone 10 receives the completion notice,
Post-processing such as deletion of the backup data that has been transferred in the mobile phone 10, setting of a backup completion flag, updating of the backup history, etc. is performed, and the sequence ends.
As a result, the backup can be performed mainly by the network, and the user is relieved of the complexity of the backup. The backup trigger may occur at regular time intervals such as once a week or once a month. This time interval may be determined or changed by the user, or may be input as an initial setting. Further, the user may be allowed to set an arbitrary date and time for backup. Further, the date and time of the next backup may be set at the end of the backup. The server may then back up multiple backup files. Further, the history of backup may be retained.

FIG. 6 shows a sequence diagram when backup is carried out from the mobile phone 10 side. When the backup trigger occurs on the mobile phone 10 side, the backup start request is issued from the mobile phone 10 side. When the backup server 123 receives the backup start request, the backup server 123 returns the backup start response to the mobile phone 10 after performing authentication processing of the mobile phone 10 and confirmation of the already stored backup file capacity. The mobile phone 10 that has received the backup start response confirms that backup data is not currently being created, and returns a backup start response. After that, the same processing as the sequence of FIG. 6 is performed. Data can be immediately backed up by the user himself designating immediate backup using the mobile phone 10. As a result, backup can be performed according to the situation, and an excellent data management method can be provided.

As shown in FIGS. 5 and 6, the backup file is provided separately from the file currently in use, and is saved in the backup area of the storage unit 34 of the mobile phone 10. Therefore, the data can be further updated on the mobile phone 10 even during the backup. Mobile phone 1 while creating a backup file on mobile phone 1
When the backup start request is notified to 0, the backup start response NG is returned. Backup start response NG
The backup server 123 that has received the request can also perform retry after a certain period of time, according to the backup trigger setting S12 of FIG. As a result, the reliability of backup processing can be increased. Similarly, even when the backup start request is notified while the mobile phone 10 is performing another operation, the backup start response NG is returned. Then, if the retry is performed after a certain period of time, the backup can be performed after the user's operation is completed. This allows backup to be performed without disturbing the operation. Further, the retry may be performed even when the backup start response NG or the backup start response OK is not returned for a certain time or more when the backup start request is notified. Further, it is desirable to stop the backup and notify the user when the backup start response OK is not returned even after retrying a certain number of times. For example, an e-mail saying "Could not be backed up" may be sent, and further, display section 32 may display "Could not be backed up".

Next, FIG. 7 shows a procedure for restoring the backup data to the mobile phone 10 or the external terminal 15. Restoration is performed by the mobile phone 10 or the external terminal 15
Start by specifying from the operation screen of. The user uses the restore screen (S20) displayed after the start of the restore to select a file to be restored from the backed up files (S21) and specify whether to delete the backup file from the backup server 123 after the restore ( S22). After the designated items are completed, the restore process is started (S23). If the same backup data as the backup data to be restored already exists in the mobile phone 10, confirmation of data overwriting (S
24) is performed. If the user accepts the overwriting, the data is overwritten (S25) and the process ends. If the overwriting is rejected, the restoration process is terminated.

Next, FIG. 8 shows a backup data restore sequence. Restore start in FIG. 7 (S23)
With the trigger as a trigger, the mobile phone 10 / external terminal 15 notifies the backup server 123 of a restore start request. The restore start request may include information such as the file name of the file to be restored. The backup server 123 that has received the notification confirms the existence of the requested file and returns a restore start response. After that, the backup data is transferred to the mobile phone 10 / external terminal 15 side. Further, when the restore start request is notified, a list of the data backed up by the backup server may be transmitted, and the user may select the file to be restored from the list. Depending on the size of the backup data, the data may be appropriately divided and transferred. Further, the handshake method at the time of data transfer is arbitrary, and an Ack from the mobile phone 10 / external terminal 15 side may be waited in units of divided packets.

When the transfer of the backup data to be transferred to the mobile phone 10 / external terminal 15 is completed, the backup server side sends a restore end notification. The mobile phone 10 / external terminal 15 receiving the end notification message
The file is closed, the process is terminated, and a completion notice is transferred to the backup server 123. By including the file name and size of the transferred backup file in the end notification / completion notification as data, the reliability of the sequence can be increased.

Upon receipt of the completion notice, the backup server side performs post-processing such as deleting the backup data for which transfer has been completed in the server according to the server side data setting (S22) in FIG. 7, and ends the sequence.

As described above, according to the present invention, data backup can be performed from the network side.
It is not necessary to prepare and set C etc. This makes it possible to easily back up data. When restoring from the external terminal 15, the data transmission destination is the external terminal 1 concerned.
