Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a utility processing device.

[0002]

2. Description of the Related Art Usually, a utility processing device is a backup that is stored in advance on several flexible disks in case the system, information, data, etc. in the hard disk are damaged or accidentally erased. Functions, backed up systems, information,
This refers to a device that has a restore function that returns data to the hard disk.

Conventionally, these utility processing devices have been
Even when the backup process was normally completed to the end during the backup process for a plurality of disks, no special process indicating that the process was normally completed was performed.

[0004]

Therefore, in the conventional utility processing apparatus, there is no method for judging whether the backup processing is normally completed to the end when the backup processing is performed for a plurality of sheets, or if the backup processing is interrupted midway. It was Therefore, when attempting to perform restore processing using the backup disk whose processing was interrupted after the second disk during backup processing, the restore processing was executed normally up to the interrupted disk (specifically, the interrupted file), and the operation was interrupted. Since an error message is displayed for the first time until the disc is reached, there is a problem in that the data that was partially restored and the data that was not restored are mixed in the hard disk, and the data cannot be guaranteed. It was also a waste of time.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a utility processing apparatus which does not restore by using a flexible disk whose backup has been interrupted. To do.

[0006]

In order to achieve this object, a utility processing apparatus according to the present invention stores an instruction means for instructing execution of backup processing, and the contents of the first storage means by the instruction. Execution means for continuously backing up each storage means that constitutes the second storage means group;
After the completion of the backup process, there is provided input control means for inputting end data indicating the end of backup to the first storage means of the second storage means group.

[0007]

In the utility processing apparatus of the present invention having the above configuration, when the instruction means instructs the execution of the backup processing, the execution means causes the execution means to copy the contents of the first storage means to the second storage means group. Backups are continuously made to each of the constituent storage means. After the backup processing is completed, the input control means inputs the end data indicating the end of backup to the first storage means of the second storage means group.

The external storage device 24 is provided with a control program part area 24a in which a control procedure of the processing device is stored and a data part 24b in which system, information, data and the like are stored, and is constituted by, for example, a hard disk storage device. ing.

The external storage device 25 is for backing up the contents of the external storage device 24, and for storing a control unit 25a for storing information necessary for restoration, a backed up system, information, data and the like. The data section 25b and the recording section 25c for storing the information when the backup is normally completed are provided, and are configured by a flexible disk storage device, for example.

In the RAM 23, the control program section area 23a for storing the control procedure of the processing apparatus stored in the control program section area 24a corresponding to the external storage apparatus 24, the external storage apparatus 2 when performing the backup process.
5 has a backup WORK area 23b as a bridge for storing data. In addition, a display RAM area 23c for editing screen information to be output to the display device 27 and the printer 28 is provided, and a control program section area of the external storage device 24 is provided in response to a signal from a key input device 26 described later. 24
The storage content of a is the control program area 23 of the RAM 23.
The data in the external storage device 24 or the like is written in the data portion 25b of the external storage device 25.

The key input device 26 includes alphabetic keys 26a to 26z, an execution key 126a, a cancel key 126b, and the like. The alphabetic keys 26a to 26z are keys for starting the utility, selecting a backup source drive or a backup destination drive, and setting a table of contents for distinguishing from a disk backed up on another day or another time, The execution key 126a is a key for starting the backup process, and the cancel key 126b is a key for interrupting the backup process midway.

Next, the operation will be described with reference to the flow charts of FIGS.

When the power is turned on and the utility is activated, the storage contents of the control program section area 24a are written in the control program section area 23a, and the utility function selection screen stored in the control program section area 23a is displayed in the display RAM area. In 23c, the data is expanded into screen display data and displayed on the screen of the display device 27 (step S3).
1. Hereinafter, it is simply S31 and the same applies to other steps). Here, when the backup function is selected from the menu (S33), the backup processing is performed by the backup processing routine (S34). When the backup process is completed, the screen returns to the utility function selection screen (S31). When a function other than the backup function is selected on the utility function selection screen (S
33), the selected function is processed (S35). When the end is selected on the utility function selection screen (S32), the utility is ended.

The backup processing routine will be described in detail. A flexible disk is inserted into the backup destination (S41), a backup source drive and a backup destination drive are selected, a table of contents is input, and the backup processing is started (S42). Unless the process is interrupted or the backup process is not normally completed, the flexible disk is replaced until there is no data to be backed up (S41) and the backup process is continued (S42).

In the normal backup process, since it is impossible to copy the data at one time, the data is copied to the work area of the RAM by a certain fixed capacity and then copied to the flexible disk. Also in this case, when the backup process is started, a part of the stored contents of the data portion 24b of the external storage device 24 is R
It is copied to the backup WORK area 23b of the AM 23 and from the backup WORK area 23b of the RAM 23 to the data section 25b of the external storage device 25.
Further, when the free space of the data section 25b of the external storage device 25 runs out, a flexible disk replacement operation occurs.

When the backup process is interrupted midway (S43), the backup process is terminated as it is. When the backup process ends normally until the end (S4
4) The display device 27 is instructed to replace the flexible disk of the backup destination drive with the first flexible disk (S45), and "OK" is stored in the recording section 25c of the first flexible disk (S4).
6).

Next, when this backed up flexible disk is used for restoration, since "OK" is stored in the recording portion 25c of the first flexible disk, this is displayed on the display device 27 and the user By confirming and performing the restoration, the data partially restored and the data not restored are not mixed in the external storage device 24.

As is apparent from the above description, the utility processing apparatus according to the present embodiment, when the processing is normally completed to the end during the backup processing, inserts the first disk again and ends normally. By storing information indicating that, when attempting to perform a restore process using a disk for which backup processing has been interrupted, it is determined that the disk is not a normal disk before starting the process and the restore process is performed. By disabling this, it is possible to prevent the mixture of old and new data, guarantee the data, and have the effect that the processing can be performed promptly.

The present invention is not limited to the embodiments described in detail above, and modifications can be made without departing from the spirit of the invention.

[0022]

As is apparent from the above description,
The utility processing apparatus of the present invention stores the end data indicating the normal end in the first storage unit of the second storage unit group again when the processing ends normally during the backup When you try to perform a restore process using the storage means that interrupted the process, you can judge that the disk is not normal before starting the process and disable the restore process. It is possible to prevent data from being mixed with each other and guarantee the data, and it is possible to perform the processing promptly.
