The present invention relates to a data backup system, and more particularly, to a data backup system that can prevent the loss of data when the power off.

As office equipment such as computers, printers, copiers and fax machines have become more advanced and commonly used, users of these office devices can document the data they want and easily perform printing, copying, and sending and receiving operations. .

During the use of such an office device, a user changes a setting value using a menu in order to obtain a desired result when printing, copying, or transmitting documented data. For example, in the case of a printer, a function such as setting a layout of a paper to be printed or setting a resolution of printed matter can be set as desired by the user.

However, after the user changes the various menus to the desired setting values, when the user turns off the device, the changed setting values are changed back to the default values before the user changes them. Therefore, if a user wants to print, copy, scan, etc. using the same setting value, the user must change the setting value again using each menu.

As a solution to this, a method of unconditionally storing the user-changed settings may be presented. However, some of the user-changed settings may be changed for temporary use only for a specific task. It's a way of not meeting demand.

On the other hand, data that may be lost when the device is powered off may vary in addition to the menu setting values. In the case of a fax, information generated when the fax data is transmitted and received, for example, whether the fax data has been sent or received, the date of transmission or reception, the receiving fax number at the sending, and the sending fax number at the receiving are stored. This information is also deleted when the power is turned off.

However, in the case of the fax, since information is more likely to be leaked than other devices, there is a problem in that information leakage cannot be blocked when information generated during transmission and reception of fax data is deleted.

Accordingly, it is an object of the present invention to provide a data backup system that can facilitate the user's convenience and prevent information leakage by enabling data loss to be prevented at power off.

The configuration of the present invention for achieving this object, the backup extraction unit for extracting a variety of information generated by the user's input or operation of the device during use of the device; A memory for storing the information extracted by the backup extracting unit; And a backup controller configured to display information extracted by the backup extracting unit to the outside and store at least some of the information in the memory when the power-off is selected by the user.

Preferably, the backup extractor extracts at least one of menu setting information changed by the user and recording information about input / output of data during use of the device.

Preferably, the backup controller stores information selected by the user among the displayed information in the memory.

When the remaining capacity of the memory is less than the capacity of the information extracted by the backup extracting unit, the backup controller may extract information that can be stored in the memory from among the information based on a predetermined reference.

When the remaining capacity of the memory is smaller than the capacity of the information extracted by the backup extracting unit, the backup controller displays all of the extracted information, and the user selects the information to be stored in the memory from the extracted information. Messages can be displayed.

The ring input detecting unit 22 detects a ring signal which is called to connect to the receiving side facsimile when the fax data is transmitted from the transmitting side facsimile.

When the ring input detection unit 22 detects the ring signal, the protocol processing unit 23 transmits information on the reception capability of the receiving side facsimile to the sending side facsimile using the fax protocol. The receiving facsimile is set in the fax mode determined by the sending facsimile according to the receiving capability of the receiving facsimile.

The fax memory 25 temporarily stores the received fax data, and stores whether or not a forward function is set for the sending side fax which sent the fax data. In addition, the fax memory 25 includes journal data, report data, and trace data, which are information on a fax number, a reception date and time of a sending side fax, and whether or not a fax is transmitted or received. (Trace data) and the like are stored, and the journal data is stored in the fax memory 25 until power off.

The fax receiver 24 receives the demodulated digital signal from the fax modem 21.

The fax transmitter 26 transmits the fax data set to the forward function among the fax data received by the fax receiver 24 to the forward fax machine, or the fax data input by the user to the fax number entered by the user. send.

The backup unit 30 includes a backup extraction unit 33, a backup memory 35, and a backup control unit 31.
