Abstract

PURPOSE:To safely perform restoring processing by regenerating identification information when the identification information is lost, and copying the data of a first storing means, for instance, in which a fault occurred on a second storing means. CONSTITUTION:A CPU 1 to control a whole device, a keyboard 3 for inputting various kinds of information for operating the device, and the first and the second storage devices 5,6 capable of preserving each data, etc., are provided. In the case where the restoration of an identification record comes to be required no account of the fault, the data and the identification record restored in response to the necessity are copied from the first storage device 5 in which the fault occurred to the normal second storage device 6. Thus, the data with the normal identification record is obtained on the second storage device 6 without changing the stored contents of a faulty medium.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing apparatus having a function of saving created or edited documents or images.

[Prior Art] As a method of searching for a target document from among a large amount of data such as documents stored in a storage device, there is a method of attaching an identification record to each document and searching for the target document from the contents of the identification record. Here, the contents of the identification record include the name of one document, the date and time of registration, the date and time of last update, and keywords for search.

In such a device, a means is required to prevent the document data itself from being unable to be processed when the contents of the identification record become unreadable due to some kind of failure. For this purpose, there is a method of checking whether the corresponding identification record can be read from the existing document data file, and if it cannot be read, repairing the identification record using a predetermined method.

[Problems to be Solved by the Invention] However, in the conventional identification record repair method described above, the repair record is written on the same storage medium (faulty storage medium) in which the record to be repaired was written. Because it was reverted, it had the following drawbacks.

(1) It is necessary to write a repair record, but if the storage medium is nearly 100% written before the failure and there is not enough free space, the repair record will not be written.

(2) This is the case when an error occurs in the content written to the storage medium and the identification record needs to be repaired.

In order to investigate the details of a problem, it is often desirable not to perform any write processing on the storage medium, but to store it in its original form until the cause of the problem can be determined.

[Means for Solving the Problems (and Effects)] According to the present invention, when an identification record needs to be repaired due to a fault, the data and the repaired identification record as necessary are transferred to the faulty memory. Copy from one medium to another good storage medium. As a result, data having a normal identification record can be obtained on another storage medium without changing the recorded contents of the faulty medium. Furthermore, when the copy destination is a replaceable storage medium, when copying data and identification records, the free space of the copy destination is checked sequentially, so that at most one data and identification record can be copied. If so, the data and identification records on the failed storage medium can be copied to the normal storage medium(s) in the correct format.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[Description of the structure of the document processing apparatus (FIG. 1)] FIG. 1 is a block diagram of the structure of the information processing apparatus in this embodiment.

In the figure, l is a CPU that controls the entire device. Reference numeral 2 denotes a memory, which stores a document editing program executed by the CPUI and a processing procedure shown in a flowchart of FIG. 3, which will be described later. Reference numeral 3 denotes a keyboard, which is an input means for inputting various information for operating the apparatus. 4 is a display device for displaying documents and processing results. Reference numerals 5 and 6 are storage devices capable of storing each data shown in FIG. 2, which will be described later. In this embodiment, it is assumed that the storage device 5 stores data whose identification information is faulty. At this time, the storage device 6 has sufficient write capacity to store all the data in the storage device 5, or the storage device 6 stores the data in the set removable storage medium. However, it is assumed that the storage medium has a write capacity sufficient to store at least the maximum size of data stored in the storage device 5 and its identification record.

[Description of Data Management (Fig. 2)] Fig. 2 shows an example of document data and identification records stored in a storage device, and 20 in Fig. 0 is a document file in which data is stored. Each document file is distinguished within the storage device by file names a, , a, and "an."

21 is an identification record file consisting of identification records of each document file. The identification record (21c) is composed of a file name field (21a) and an identification information field (21b). The file name field stores the file name of the document file corresponding to the identification record. The identification information field stores identification information added to a document by an operator in order to identify one text file.

[Explanation of Processing Procedure (FIG. 3)] Next, the processing procedure executed by the CPU in this embodiment will be explained according to the flowchart of FIG. 3.

There is a failure in the identification record of storage device A (5), its contents are repaired, and the repaired identification record is written to storage device 1B (6) together with the corresponding document data.

First, in 5301, the document file name list in the storage device 5 is read. The total number of document files is n, and each document file name is a+, a*"an. In 5302, the processed document is stored in the memory area FN. Set φ to the number of files i.53
If i is greater than or equal to n in step 03, all document files have been processed, so the process ends. 53 when i is less than n
Proceed to step 04 and increase the value of i by 1. 5305, checks whether the storage medium on the storage device 6 has enough free space to write the i-th document file (file name ai) in the storage device 5 and its corresponding identification data. do. If there is insufficient free space, proceed to step 33.
At step 06, the storage medium is replaced, and an instruction is output to the CRT to instruct the replacement of the storage medium. Execute 5305 again. If there is free space.

Checks whether the identification record corresponding to the i-th document in the storage medium of the storage device 5 can be read (S307). If the classification code can be read, the contents are read into the memory DN (S308) and the identification record is read. If it cannot be read, a new identification record is created in the memory DN using the keyboard according to a predetermined procedure (S309
), 5310 writes the identification record of the memory DN to the storage device B6, and furthermore, after copying the i-th document file from the storage device A to B in S 311, the process returns to 5303.
Return to and repeat the process.

The above explanation did not mention how to recreate the contents of the identification record that could not be read. This method may be of any type, such as (1) identification with a default value;
(2) If the document file name is created based on specific information such as the date of creation, restore that information from the file name and use it as identification information. For example, how to create an identification record with

[Other Embodiments] In the above embodiment, all the document data in the storage layer A is written to the storage device B together with the identification records that have been repaired as necessary. A method of writing together with the document data may also be considered.

This has the advantage that the amount of data read/write is reduced and the processing speed is increased.

In the above example, one document data is used, but it is obvious that the type of data is not limited to a document, and may also be an image.

[Effect of the invention] As explained above, the present invention has the following effects.

(1) For storage devices with document data and part of the identification/coat failure, by writing all document data and, if necessary, repaired identification records to other normal storage media. , the repair process can be performed safely without running out of write capacity.

(2) During processing, no write processing is performed on the data in the faulty storage device, so even after processing, the data can be saved in the same form as when the fault occurred, and the data can be saved from the faulty storage device. The cause can be easily investigated.
