5.1 Overview of Backup and Recovery

This section provides an overview of Shunsaku's backup and recovery functions.

• Backup Function
• Recovery Function

Backup

"Backup" refers to the process of saving the data needed for Shunsaku operation to guard against data loss caused by disk corruption and so on.

To restore data, the following files must be backed up:

• Shunsaku environment files
• Direct access key definition file
• Director data files

Shunsaku Environment Files

Back up the Shunsaku environment files if any of the execution parameters in the files have been changed.

The files to be backed up are stored in the following locations:

Environment file	Location
System environment file	Shunsaku installation folder\Shunsaku\etc\system\Shunsaku system name.cfg
Conductor environment file	Shunsaku installation folder\Shunsaku\etc\conductor\conductor-identifier.cfg
Director environment file	Shunsaku installation folder\Shunsaku\etc\director\director-identifier.cfg
Sorter environment file	Shunsaku installation folder\Shunsaku\etc\sorter\sorter-identifier.cfg
Searcher environment file	Shunsaku installation folder\Shunsaku\etc\searcher\searcher-identifier.cfg

Environment file	Location
System environment file	/etc/opt/FJSVshnsk/etc/system/Shunsaku system name.cfg
Conductor environment file	/etc/opt/FJSVshnsk/etc/conductor/conductor-identifier.cfg
Director environment file	/etc/opt/FJSVshnsk/etc/director/director-identifier.cfg
Sorter environment file	/etc/opt/FJSVshnsk/etc/sorter/sorter-identifier.cfg
Searcher environment file	/etc/opt/FJSVshnsk/etc/searcher/searcher-identifier.cfg

Refer to 5.2 Backing Up and Restoring the Shunsaku Environment Files for more details.

Direct Access Key Definition File

A direct access key definition file is the definition file for the direct access function.
The direct access key definition file should be backed up together with the director environment file.The direct access key definition file is located in the following directory:

Shunsaku installation folder\Shunsaku\etc\director\

/etc/opt/FJSVshnsk/etc/director/

Refer to the Application Development Guide for more information on the direct access key definition file and the direct access function.

Director Data Files

Perform backups according to a backup cycle that matches the operations performed by a user.

Back up all files in the folder that has the name of the director identifier and is located in the directory specified by the DataFileFolder parameter in the director environment file.

Refer to 5.1.2 Backup Cycle for more information on the backup cycle.

Recovery

"Recovery" refers to the process of using backup data to restore Shunsaku to a state in which it can start operating again. Select the operation that matches the business objectives when using the operation log file.

In Shunsaku, recovery can be used to restore the following files.

• Shunsaku environment files
• Director data files:
  • Recovery to a point immediately preceding a malfunction
  • Recovery to a backup point
  • Recovery to a specified point

  The procedure used to recover director data files differs depending on whether operation log files are used.

• Operation log files

The operation log file is important when recovering the above files. Therefore, the operation log file must be recovered immediately if the disk fault occurs. Follow the same procedure in 5.2.2 Recovery to recover the direct access key definition file.
