[0002]

2. Description of the Related Art Information processing systems, which connect computers such as office computers and workstations (WS) including a personal computer LAN to each other to realize sharing of printers, sharing of data, etc., have been rapidly spread. Until a few years ago, a system in which a large number of expensive computers are used as server devices has higher cost and higher performance than personal computers, but a plurality of WSs, which are lower in cost than large computers, are mainly connected. In addition, a dedicated department that controls and manages the system is established to carry out various operations such as data backup, instruction to users, response to troubles, and planning of equipment addition / update plans.

Recently, performance improvement of personal computers, L for personal computers
Due to the enhancement of AN-related products, PC LA can be used in a single department.
It has become common to introduce N and operate and manage it only within the department. This allows system administrators to be appointed according to the scale of the personal computer LAN provided in the department.
Is operated and managed. The system administrator carries out various management tasks performed by the dedicated management section, while performing the tasks of the main body of his / her department. While the user side has become more convenient, the administrator has to do more work and has become a burden.

Data backup work is carried out once a week by the system administrator during the time when there is no user of the personal computer LAN (before work, after work, and in some cases on holiday), the data saved in the card disk in the server device. Data backup device (optical disc device, cassette MT
The device etc.) is performing the copy operation on the corresponding medium. As a result, the influence (data loss, destruction, etc.) when the hard disk in the server is abnormal is minimized.

[0005]

However, the above-mentioned conventional data backup device has the following problems.

(1) Data must be backed up after working hours once a week. Therefore, it takes 30 minutes to 1 hour, sometimes 2 depending on the amount of data to be copied, until the system administrator finishes copying from the disk in the server device to the backup device to the recording medium.
I can't go home because I'm restrained for more than time.

(2) Since a general-purpose personal computer is used, it cannot withstand continuous operation 24 hours a day, 365 days a year. Therefore, the service life of the system is likely to be shortened unless the personal computer LAN is started up every day and the necessary termination operation is performed at the end to turn off all the power supplies.

For this reason, only the server device is expensive WS
However, it is necessary to use a more expensive server-dedicated machine instead of a general-purpose machine even with WS. It seems that it is impossible on budget to install a dedicated server machine in one department of several tens of people.

UNIX, which is the mainstream OS of WS,
Unlike MS-DOS and Windows, it is not possible to acquire technology in a short period of time.

Personal computer LA whose main purpose is to improve work efficiency
The investment amount of N cannot be recovered in a few years, and it takes a considerable period to start up the system.

(3) The reliability of the data backup command of the general network OS "NetWare" of the personal computer LAN is low.

The present invention has been made in view of the above-mentioned problems of the prior art, and its object is to provide automatic data of a server in a personal computer LAN capable of automating the backup work of data performed after the end of business. To provide a backup device.
