Abstract

PURPOSE:To support the speedup of file restoring processing and the integration of backup operation by commonly and 5 unitarily managing the file backup processing of various works in a computer systems. CONSTITUTION:A maintenance means 1 registers/corrects/deletes the backup timing/medium name/stored period information of each file in/from a backup management file 21. A monitoring means 3 interlocking with a job managing means 7 automatically detects backup timing on the way of work execution from the file 21. An interruption means 4 acquires the timing information detected by the means 3 and informs interruption specifying information. A result collecting means 5 collects the end status of a backup program JCL obtained from the means 4 as execution history information. Thus this file backup method especially displays its effects for the unification of backup processing operation and the speedup of file restoring processing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for centrally managing file backup processing operations for recovering from a backup file before a failure when a file fails in a computer system.

[0002]

2. Description of the Related Art Conventionally, in the operation of file backup processing, the JCL of the backup service program is incorporated in the individual business JCL, or at the timing set appropriately for each business or at the end of all the business every day / month / year. The JCL of the backup service program was started, the backup timing, method, medium name, and retention period were different, and the management of the backup execution history was a manual task.

[0003]

The above-mentioned conventional backup processing is intended for files that are required by a person in charge of business for each business, and the backup execution history is manually managed. It has the disadvantage of frying. (1) The backup execution history of the entire computer system cannot be provided as magnetized information. (2) It is difficult to set the operation administrator for file backup of the entire computer system (3) It is difficult to judge the necessity of backup processing for each file (4) The search time of the backup file required at the time of restoration is long (5) Backup service Create JCL of program,
In some cases, it is necessary to incorporate it into the work JCL. (6) (5) is a manual work, so there is a possibility that faults may be triggered by a malfunction.

According to the file backup method of the present invention, a backup management file for storing information for backup by a backup file for each file and a backup service for a file instructed from the information of the backup management file are provided. Automatic creation means for automatically creating a program, job management means for a computer system, monitoring means for detecting backup timing from information in the backup management file and creating interrupt instruction information for a backup service program, and the interrupt instruction information An interrupt means for notifying the job management means and the supervisor means of acquiring the end status of the backup service program submitted for execution and notifying the job management means of the suspension of the job JCL, and a backup server. The record information after the screws program ends and a result collection means for registering the backup management files.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.

As shown in FIG. 1, in this embodiment, a maintenance means 1 and an automatic generation means 2 for carrying out the processing of the operation preparation stage 11, a monitoring means 3 for carrying out the processing of the actual operation stage 12, an interruption means 5, a job management means 7 are provided. And supervisor means 8 and providing means 6 for performing the processing of the operation evaluation stage 13.

The maintenance means 1 registers, corrects, and deletes backup timing (date time designation, job JCLSTEP designation), method (service program), medium name, and retention period information in the backup management file 21 for each file.

The automatic creating means 2 uses the information in the backup management file 21 to create the backup service program J.
CL is created automatically.

The monitoring means 3 works in conjunction with the job management means 7 provided as a standard in the computer system to check the backup timing during the execution of the work in the backup management file 21.
Automatically detect from.

The interrupt means 4 acquires the timing information detected by the monitoring means 3, notifies the job management means 7 and supervisor means 8 provided by the computer system of the interrupt instruction information, and acquires the end state from these means. To do.

The performance collecting means 5 collects the end status of the backup service program JCL acquired from the interrupting means 4 and uses it as execution history information.

The providing means 6 outputs a backup execution history report 23 for grasping the overall operation of the backup process, determining the necessity of backup for each file, and speeding up the file recovery process.

Next, the operation preparation stage 11, the actual operation stage 12 and the operation evaluation stage 13 of this embodiment will be described with reference to the process flow charts of FIGS. 2, 3 and 4, respectively.

At the operation preparation stage shown in FIG. 2, maintenance means 1 is used.
Enter the backup timing, method, medium name, and retention period information of the target file using the backup management information registration screen illustrated in FIG. 5 and register it in the backup management file after checking the consistency of the input items ( Steps 1S1, 1S2, 1S3, 1S4, 1S8). In the backup management information for each file, the automatic creation means 2 automatically creates the JCL for the file for which the automatic creation instruction of the backup service program JCL is given.
Register to CL storage file (steps 2S5, 2S
6, 2S7).

At the actual operation stage shown in FIG. 3, the monitoring means 3
Steps 3S10 to 5S17 and 5S18 from the system operator instructing to end the operation
The above process is repeated (step 3S9). Backup management information for each file of the backup management file 21 and the job schedule status acquired from the job management means 7
The file backup timing is detected from the task execution status, and an interrupt instruction (holding instruction of the running job JCL, interrupt instruction, backup service program J
Create CL identification name information (step 3S1)
0, 3S11, 3S12, 3S13).

Next, in order to execute the interrupt, the interrupt means 4 notifies the job management means 7 and the supervisor means 8 of the interrupt instruction information and requests execution. After monitoring the execution status of the requested backup service program JCL and acquiring the end status, the job management function 7 is notified of the hold cancellation instruction of the business JCL (steps S14, S4, S4).
S15). After recognizing the normal termination of the backup service program JCL, the performance collecting means 5 registers the performance information (execution history information) in the backup management file (steps 5S16, 5S17, 5S18).

At the operation evaluation stage in FIG. 4, the providing means 6 outputs the backup execution history report 23 based on the request to provide the record information (execution history information), and backs up all files managed by the backup management file 21. The execution history / execution schedule information is provided (steps 6S19, 6S20, 6S21, 6S22).

[0018]

As described above, according to the present invention, it is possible to commonly and centrally manage the file backup processing which has been operated for each of various various operations of the computer system. Therefore, the recovery process at the time of a file failure can be speeded up. Furthermore,
The overall operation management that grasps the backup operation and judges the adequacy of the entire computer system functions functionally, and further improves the safety work performance of the computer system.
