The present invention relates to a data backup method of a computer, and in particular, a large amount of program data input from a terminal in a large computer is backed up automatically while operating the computer at a predetermined predetermined time, and after the backup is completed automatically A method of backing up data of a computer that is turned off.

Generally, a large computer used in a government office or a company receives a large amount of program data from each terminal through an online computer operating system called UNIX or XENIX in a main computer, and the received data is stored in a backup drive. After backing up the data in the main computer, the program is backed up and processed by a predetermined program of the main computer. You will not be able to back it up.

Because if the backup is received during the operation of the main computer, the amount of work on the main computer increases, and there is a risk that data may be broken or an error may occur. Since a large amount of data is input from each terminal, it takes 2-3 hours to back up this large amount of data.

Therefore, since the worker is backed up after work and after work, the employee has to wait for the backup to complete and then have to leave the office when the backup is completed.

Accordingly, an object of the present invention is to automatically turn on and off the power of the computer with an external timer, and set the backup time arbitrarily in the computer to automatically back up the program data input from the terminal at the arbitrarily set backup time, and after the backup is completed. Is to make backup of data more convenient by turning off the computer.

In order to realize the above object, the present invention determines whether the power on / off time of the computer is set in the state in which the power on and off time of the computer is set in the external timer, and if so, the computer turns on at the power on time. Determining whether the power is turned on; if the computer is turned on in this step, operating the computer and inputting data backup time and processing instructions arbitrarily; Determining whether the backup time has been reached, if the backup time has not been reached, start the computer, and if the backup time has been reached, operating the backup command, and if the backup is activated in the above step, backing up the data. Of course, it executes the processing command entered by the user and saves the situation occurring during the execution of the command as a message file. When the step and is performed to back up and instruction completion at the stage characterized by made of an step of turning off the power to the computer.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a control block diagram of a data backup method of a computer of the present invention, wherein a timer is set to turn on and off an arbitrary time with respect to a power supply voltage input from an external power supply terminal AC, and the timer A main computer (C) for receiving a power ON / OFF signal from a terminal and storing a data input from each terminal (B) by a predetermined program and outputting a predetermined controlled and controlled signal; According to the control signal output from the main computer (C) it is composed of a backup drive (D) for backing up and storing a large amount of data stored in the main computer (C).

2 is a flowchart of a data backup method of a computer of the present invention, comprising: a computer on and off time setting judging step 20 for determining whether an arbitrary computer power on or off time is set in an external timer, and the computer on, If the power-on time of the computer is arbitrarily set in the off-time setting judging step 20, the computer power-on judging step 21 for judging whether the computer power-on time has been reached and the computer power-on judging step 21 If it is determined that the computer is not powered on, the computer waits until the computer is turned on, and if the computer is powered on, the computer operating standby step 22 of waiting for the operation of the computer and the computer operating standby In step 22, a command for arbitrarily inputting or processing a time for backing up data of each terminal input while the computer is in standby mode is executed. Backup to determine whether the backup time has been reached in the state where the backup time and processing command input step 23 and the backup time and processing command input step 23 are set arbitrarily or the backup time of the previous state is input. When the backup time is reached in the time judging step 24 and the backup time judging step 24, data backup and processing command for backing up the data input by the backup command and executing the program by the user's desired processing command A message file storing step 26 for storing a data file processed in the performing step 25, the data backup and processing command execution step 25, and the processing occurring in the execution of the command in a message file; In the storing step 26, it is determined whether the message storage is completed, and the message file storing completion determination step 27 and the message file storing completion determining step 27 As a result of the determination, if the message file storage is not completed, the message file is repeatedly stored until the message file storage is completed, and when the message file storage is completed, the computer power off step 28 is performed to turn off the computer.

Referring to the effects of the present invention made as described above are as follows.

First, the worker sets the power on and off time of the host computer C arbitrarily in the timer.

Subsequently, the main computer (c) goes to the computer power on and off time setting judging step 20 to determine whether the computer power on and off time is set in the timer. If the computer power on and off time is not set in the timer, the timer maintains the standby state until the computer power on and off time is set. If the computer power on and off time is set as the result of the determination, The main computer (c) goes to the computer power-on determination step 21 to determine whether the computer power-on time is up. If the computer power-on time is not determined, the main computer (c) is in a standby state until the computer power-on time is reached. do.

Subsequently, when the computer power-on time is reached in the computer power-on determination step 21, the main computer (C) goes to the computer operation standby step 22 to wait for the main computer (C) to operate, and then the backup time and processing instruction. Going to the input step (23), the main computer (c) is input to the backup time and the command to be processed during the backup time arbitrarily in a convenient time zone.

In the state where the backup time and the processing instruction are input in this way, the main computer (C) goes to the backup time determination step 24 and determines whether the time of the currently running timer has reached the backup time set arbitrarily. At this time, if it is determined that the backup time has not been reached, the host computer (C) displays the backup time and processing instructions while waiting for the operation until the arbitrarily set backup time is reached from the computer operation standby step 22. Then, if the backup time has been reached in the backup time determination step 24, the host computer (c) goes to the data backup and processing instruction execution step 25, each terminal by a predetermined program set in advance. In addition to backing up the program data entered during the operation of the main computer from (b) to the backup driver (d), The operation is performed according to the displayed processing instruction, and the main computer (c) goes to the message file storage step 26 to store messages such as processing and errors generated during the backup and processing instructions in the message file. Data backup and processing instructions.

Subsequently, the host computer (c) proceeds to the data backup and processing instruction execution completion determination step 27 to determine whether the data backup and processing instruction execution is completed, and if the data backup and processing instruction execution is not completed, the In the main computer C, the data backup and processing instruction execution step 25 is repeated until the data backup and processing instruction execution is completed, and the data backup is performed in the data backup and processing instruction execution completion determination step 27. And when the execution of the processing instruction is completed, the main computer (c) goes to the computer power off step 28, and the main computer (c) is powered off by the computer power off time set by the timer. The above process is repeated while turning on the host computer again by the computer power-on time set in the timer. At this time, if the worker sets the backup time arbitrarily at a desired time zone, the data backup time is automatically performed at a randomly set time unless the backup time is changed.

As described above, the present invention automatically turns on and off a large computer power supply using an external timer, and arbitrarily sets a data backup time of a computer to arbitrarily set a large amount of program data input from a terminal. By backing up the computer automatically while the computer is running, and turning off the computer after the backup is completed, it is possible to solve the inconvenience of having to perform backup work while working outside of working hours to back up data to the computer. Will be.
