Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention has an input device for inputting data, a display device for displaying figures and characters, an external storage device for storing data, and a data for storing data. The present invention relates to a so-called backup management device as a server computer having a main storage device, a backup means for backing up from the main storage device to the external storage device, etc.

[0002]

2. Description of the Related Art Due to miniaturization of workstations and enhancement of network management functions, client / server type operation in which workstations are connected to a network has been increasing from conventional stand-alone operation or centralized management by a general-purpose machine.

Here, the client / server type will be briefly described. The client / server type divides the system into two functional units, a client computer and a server computer. The server computer is a computer that provides a specific service in response to a request from the client computer, and the client computer is a computer that requests a service from the server computer.

Since client / server type operation has increased, data maintenance on the network has become important in recent years. Various means are currently considered as means for maintaining data on a network. One of them is a method in which a server computer, a so-called backup management device, saves data on a tape medium, for example. is there. Generally, the backup management device has a configuration as shown in FIG.

Reference numeral 1 is a server computer, 2 is an input device for inputting data, 3 is a display device for displaying characters and graphics, 4 is a main storage device for storing data to be backed up, and 5 is data storage. External storage device for
6 is a server computer 1 and a client computer
A network for performing communication (not shown), 7 is a network control device for controlling the network 6, 8
Is a central processing unit that controls the entire server computer 1.

Further, the server computer 1 includes an input control means 11 for controlling the input device 2 and the display device 3.
Display control means 12, a backup means 13 for storing data from the main storage device 4 to the external storage device 5, a network state acquisition means 14 for reading usage information of each client computer, and the network 6. The network control means 15 is configured to operate.

[0007] Next, an outline of the operation will be described. When performing backup, first, each client computer 19 provided by the operating system, which will be described later, will be described.
(See Fig. 2) Input the commands to check the power on / off, login presence / absence, and application start-up from the input device 2. The client computer, which has transmitted and received, transmits the presence / absence of application activation to the server computer 1.

Then, the server computer 1 turns on / off the power of each client computer, whether or not there is a login,
After confirming whether or not the application is started, the application on the client computer is stopped by inputting the application stop command from the server computer 1 to the client computer using the application with the input device 2, and the main storage device 4 externally The data was stored in the storage device 5.

[0009]

However, in the above-described conventional data storage method by the backup management device, since the application running on the client computer operates regardless of whether or not the data is accessed, the server computer is used. After confirming with the client computer user that the application has stopped, the backup means must save the data, and there is no way for the client computer user to know the backup status. Was.

The present invention solves the above conventional problems, allows the user of the client computer to know the backup state, and further reduces the manual input operation accompanying the backup work of the server computer for backup, and The purpose is to reduce the work time for saving data.

[0011]

In order to solve the above problems and achieve the object, the present invention is a means for a server computer to create a message for informing each client computer at the start and end of backup execution. And means for sending a message to each client computer. Also, turn on / off the power of each client computer, whether there is a login,
And a means for the server computer user to select whether or not to execute the backup depending on whether or not the application is activated.

Further, it has means for stopping the application on each client computer before the server computer saves the data in the main memory.

[0013]

According to the present invention, each of the above means is utilized to
When the server computer user notifies the client computer in the network of the backup start or end message, the client computer user can quickly grasp the backup status. Since only the operation is selected by the button, the manual input operation required for the data saving work can be simplified and the working time can be shortened.
