Abstract

PURPOSE:To copy desired number of filing systems with a simple operation by unifying the filing systems based on reference relation between them and copying the filing system on another information storage medium. CONSTITUTION:The filing systems 7A-7C designated by one time of operation and reference filing systems 7E, 7G in a directories included in designated filing systems 7A-7C and relating to the designated filing systems 7A, 7C are unified based on the reference relation between the filing systems, and they are copied on another information storage medium (magnetic tape 9). Also, the magnetic tape 9 is used as the information storage medium to copy a designated volume, however, a magnetic disk, a floppy disk, or a magneto-optical disk, etc., can be also used as the information storage medium. Therefore, a user can copy the desired number of filing systems with the simple operation without being conscious of the number or the mutual reference relation of filing systems to be copied.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file management system for managing a plurality of files as a hierarchical file system, and more particularly to a file system management system for carrying out a process of copying a file system.

[0002]

2. Description of the Related Art As a conventional file system management system of this type, for example, there is one described in "UNIX System V System Administration Reference Manual Second Edition Release 3.0". FIG. 3 is a configuration diagram for explaining the processing of such a conventional file system management method. This conventional file system management system has a VOLCOPY (copy of the file system as it is) function. In FIG. 3, 6 is a logical volume that logically stores the file systems 7A to 7G, 8A and 8B are physically independent physical volumes that constitute the logical volume 6, and 9 is a magnetic field as another information storage medium. It is a tape. Half of the file systems 7A to 7C and the file system 7D are physically stored in the physical volume 8A, and half of the file system 7D and the file systems 7E to 7G are physically stored in the physical volume 8B. The physical volumes 8A and 8B are information storage media, and are realized by magnetic tapes, floppy disks, magneto-optical disks, and the like.

Next, the operation of this conventional file system management system will be described. In FIG. 3, for example, the file system 7B stored in the physical volume 8A
Consider the case of performing VOLCOPY (copying). The processing device (not shown) designates the file system 7B of the physical volume 8A as a file system for copying, logically recognizes this file system 7B as one file, and directly designates the file system 7B as a parameter when the program is started. This makes it possible to copy the file system 7B to the magnetic tape 9 designated as the above parameter.

[0004]

Since the conventional file system management method performs the above processing, a designated single file system can be copied, but a computer volume is composed of a plurality of file systems. Therefore, when copying a plurality of file systems, the same procedure must be performed a plurality of times, resulting in poor processing efficiency.

Therefore, in order to solve this, a hierarchical file system is configured to collectively copy a plurality of file systems designated by one operation, for example, as disclosed in Japanese Patent Laid-Open No. 3-164952. Known prior art is known. However, the prior art as described above is
Multiple file systems specified by one operation can be copied at once, but the reference file system related to that file system cannot be copied at once, so the range of use becomes narrow.

Further, in the conventional file system management method and the above-mentioned prior art, when an arbitrary file existing under an arbitrary file system is managed as another file system, the reference relationship is set to the user. It is necessary for all users, including those who have inadequate computer system management and operation experience to manage these knowledge and management methods so that the same file system must not be duplicated. It is impossible to ask.

The present invention has been made in order to solve the above problems, and at the time of copying a file system, the user does not need to be aware of the number of file systems to be copied or the mutual reference relationship, and is simple. It is an object of the present invention to provide a file system management method capable of copying a desired number of file systems by various operations.

[0008]

A file system management method according to the present invention is a file system 7A, 7B, 7C designated by a single operation and a directory included in the designated file system 7A, 7B, 7C. The reference file systems 7E and 7G related to the specified file systems 7A and 7C are collectively packaged based on the reference relationship between the file systems and copied to another information storage medium (magnetic tape 9).

[0009]

When the file systems 7A, 7B and 7C are designated by one operation, the file systems 7A, 7B and 7C
And reference file systems 7E and 7G related to these
And are combined and copied onto another information storage medium (magnetic tape 9).

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a flow chart for explaining the processing of a file system management system according to an embodiment of the present invention. FIG. 2 is a block diagram for explaining the processing of this file system management method. The operation of copying a volume (a plurality of file systems) to a magnetic tape will be described with reference to FIGS. 1 and 2. First, the parameter analysis unit 1 determines whether or not there is an abnormality in the parameter specified by one operation using a keyboard (not shown) or the like, and if there is an abnormality, moves the processing to the termination processing unit 5. In the next volume analysis unit 2, the volume designated by the parameter (file system 7A, 7B, 7C)
Also, the volumes (file systems 7E and 7G) having a reference relationship with these volumes are analyzed and selected, and if there is an abnormality, the process is moved to the end processing unit 5. In the physical volume analysis unit 3, the volume analysis unit 2
The positions and ranges (copy areas) of the volumes selected in step 2 on the physical volumes 8A and 8B are calculated, and if there is an abnormality, the process is moved to the end processing unit 5. In the copying unit 4, the contents of the volume (file systems 7A, 7B, 7C, 7E, 7
G) is copied, and if there is an abnormality, the processing is moved to the end processing unit 5.

When all the copying is completed by the above-mentioned processing, or when an abnormality is detected in the middle of the processing, the control is transferred to the ending processing section 5 to carry out the ending processing.

In the above-described embodiment, the file systems 7A, 7B and 7C designated by one operation and the related reference file systems 7E and 7G under the directories included in these file systems are set to the file system. Based on the reference relationship between them, processing is performed so that they are collectively copied to another information storage medium, in this case, the magnetic tape 9.

In the above embodiment, the magnetic tape 9 is used as the information storage medium for copying the designated volume (specifically, the designated file system and the reference file system). However, the present invention is not limited to this, and the magnetic disk, floppy disk, magneto-optical disk, etc. May be used as an information storage medium.

If the volume analysis unit 2, the physical volume analysis unit 3, and the copying unit 4 in the above embodiment include the processing related to the multi-volume of the device, the volume to be copied may be spread over a plurality of physical volumes or may be copied. It is also possible to deal with the case where there are multiple physical volumes.

[0015]

As described above, according to the present invention, a file system designated by one operation and a related reference file system under a directory included in the file system are related to each other in a reference relation. Based on
Since the information is copied to another information storage medium, when copying the file system, the user does not need to be aware of the number of file systems to be copied or the mutual reference relationship.
The effect that a desired number of file systems can be copied with a simple operation is obtained.
