Backup and restoration of system files

From the point of view of safe operation of the system, take a periodic backup of the system files in case of emergencies such as a hard disk crash.

Note

  • Make sure to terminate HULFT before you carry out backup or restoration work.

  • You cannot restore backup files to an environment that is different from the one that you created the backup files on.

Backup Method

A HULFT backup can be made by the following procedure. It is recommended that the user who installed HULFT or the Windows system administrator perform the following tasks. In this procedure, it is assumed that "HULPATH" is set as "HULFT_folder\etc." If a different HULPATH is in use, replace it with that of your environment.

1. Move to HULFT installation folder.

2. Check the environment of HULFT.

3. Move to the 'etc' folder, which is the HULPATH environment.

4. Check that the folder is the HULPATH environment.

Confirm that it is the folder which is described in the 'hulft.ini' file in the bin folder.

5. Create a backup.

Copy all the files under the environment of HULPATH into an arbitrary folder.

In this case, all files that exist in this folder are backed up. Therefore, log files are also backed up. To exclude log files from the backup, use the following commands to delete the log data beforehand.

  • Send and Receive Log Deletion command (utllog)

  • Observe Log Delete command (utlobsrm)

  • Schedule Log Deletion command (schrmlog)

6. Confirm that a backup has been created.

The backup is now complete. Retain the backup for recovery.

Method of restoration from backup

You can restore the backup by the following procedure. It is recommended that the user who installed HULFT or the Windows system administrator perform the following operations. In this procedure, it is assumed that "HULPATH" at the time of HULFT operation is "HULFT_folder\etc." If a different HULPATH is in use, replace it with that of your environment.

1. Move to the folder where the backup of HULFT management information is stored.

2. Verify the existence of the HULFT management information backup files.

3. Move to the 'etc' folder, which is the HULPATH environment.

4. Check that the folder is the HULPATH environment.

Confirm that it is the folder which is described in the 'hulft.ini' file in the bin folder.

5. To restore the backup files, copy and paste them to this folder.

After copying and pasting them, all management information will be restored to the information when the backup was created. Note that it is not possible to undo the restoration.

6. When restoration is complete, check the restoration is properly applied to the environment on the HULFT Management Console.

7. Once you confirm the environment is returned to the state when the backup is created, the restoration is complete. The backup files can be deleted if they are no longer required.
