  R80.20 JHF:

  ```
  java.nio.file.FileAlreadyExistsException: /opt/CPmds-R80.20/log/mgha/..../export_ha_dump_files.tgz
              at sun.nio.fs.UnixCopyFile.copy(UnixCopyFile.java:563)
  ```

  <br />

  R80.30 JHF:

  ```
  java.nio.file.FileAlreadyExistsException: /opt/CPmds-R80.30/log/mgha/..../export_ha_dump_files.tgz
              at sun.nio.fs.UnixCopyFile.copy(UnixCopyFile.java:563)
  ```
