Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a data backup system for workstations connected to a LAN.

(Prior Art) A block diagram of a workstation is shown in FIG. 4 to explain a conventional data backup method for this type of workstation, and a system diagram relating to a conventional data backup for a workstation connected to a LAN is shown in FIG. The configuration diagram is shown in FIG. 5. In FIG. 4,
The workstation consists of a console (1), an input control section (2), a job execution section (3), and a disk output control section (
4), a magnetic disk (5), a communication control section (6), an output control section (7), and an output medium (8). In addition, in FIG. 5, (11) is LAN, (12a),
(12b) and (12c) are the main bodies of the respective workstations, and (5a).

(5b) and (5c) are magnetic disks connected to the respective workstations, (13a) and (
13b) and (13c) are magnetic tapes for backing up data of each workstation.

In the above configuration, each magnetic disk (5a) to (5C)
The data stored in the magnetic tapes (13a) to (1
The data is copied and backed up to an external storage device such as 3c) for each workstation, and the data copying method, copying time and period are determined by the operation.

[Problem to be solved by the invention]

As mentioned above, in the conventional workstation backup method, data is backed up for each workstation. Therefore, the more workstations are connected to the LAN (11), the more time and effort it takes to perform a backup operation, which increases the burden on the operator. Also, storage of backup data using magnetic tape, etc.
Management also had to be done separately for each workstation, and the increased amount of backup data made storage and management more complicated.

This invention was made in order to solve the above problems, and it is a workstation system that can realize a system for selecting data to be backed up for each workstation and backing up the selected data all at once. The purpose is to provide a backup method.

[Means for Solving the Problems] A workstation data backup method according to the present invention provides a method for backing up data to each workstation connected to the LAN in a system in which a large number of workstations are connected to the LAN. The system is equipped with a backup selection unit that checks whether data is necessary, and a backup data transfer unit that transfers the backup data to a specific workstation that performs backup data downloading. This system is characterized by the fact that it is performed all at once.

[Effect]

In this invention, the backup selection section allows the user to determine whether or not backup is necessary each time data is generated or changed, and selects only truly necessary data. Then, the selected data is automatically transferred by the backup data transfer unit to the workstation that executes the backup. Node information for identifying which workstation the data belongs to is added to the backup data transferred at this time.

(Embodiment) The configuration of an embodiment of the present invention will be explained below with reference to FIGS. 1 and 2, in which the same parts as in FIG. 4.5 are denoted by the same reference numerals. The one that was made is LA
A backup selection unit (9) that asks the user whether or not data backup is necessary for each workstation connected to N, and a backup unit (9) that transfers the backup data to a specific workstation that executes the backup data download. and a data transfer unit (10), which allows the system to collectively back up data held by each node. In addition, as shown in Figure 2, only the workstation (12a) is provided with an external storage device such as a magnetic tape (13a), other workstations are not provided with an external storage device, and each workstation connected to the LAN is This allows you to back up only the data you need on a specific workstation.

Next, the operation will be explained with reference to the flowchart shown in FIG. When new data is created or data is updated by executing a job (S31), first, the backup selection unit (9) displays on the console an inquiry as to whether the data should be backed up (S3
2). The user determines whether the data should be backed up, and if so, responds to that effect (S
33) Data designated as requiring backup is copied by the backup selection unit (9) and passed to the backup data transfer unit (10) (534) This copied data is transferred to the backup data transfer unit (lO).
535), add node information to the file name of the data to identify which workstation it belongs to.
Transfer the data to the workstation executing the backup (53B) The workstation executing the data backup periodically sucks up the data transferred from each workstation to a magnetic tape or the like.

In the above embodiment, the user himself/herself decides which data should be backed up at each workstation, but this may also be done by backing up only specific files based on the file creation date or file name. Further, although the above embodiment describes data backup, it can also be applied to registration management of source programs, etc. by adding a log function related to backup operations.

〔Effect of the invention〕

As described above, according to the present invention, the backup selection section allows the user to determine whether or not backup is necessary each time data is generated or changed, selects only truly necessary data, and executes the backup using the backup data transfer section. Since the backup data is automatically transferred to the workstation where the data is stored, the burden on the operator performing the backup can be reduced, and a device for backing up data such as magnetic tape is not required at each workstation, making the entire system cheaper. There is a certain effect.

[Brief explanation of the drawing]

Figure 1 is a block diagram of a workstation for realizing this invention, Figure 2 is a system configuration diagram of this invention, Figure 3 is a flowchart showing the operation of this invention, and Figure 4 corresponds to Figure 1. Conventional block diagram FIG. 5 is a conventional system configuration diagram. (9) is a backup selection unit, (lO) is a backup data transfer unit, (11) is a LAN, (12a) ~
(12c) is a workstation, and (13a) is an external storage device such as a magnetic tape. In each figure, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Claims] In a system in which a large number of workstations are connected to a LAN, each workstation connected to the LAN is equipped with a backup selection unit that asks the user whether or not data backup is necessary, and a specific unit that executes the downloading of backup data. A workstation data backup method characterized in that the workstation is equipped with a backup data transfer unit for transferring backup data, and the system collectively backs up data held by each node.
