Problem conclusion

• An incorrect custom version of the 'tar' binary was invoked as
  part of the code for performing configuration backup. The custom
  binary was compiled against RHEL/CentOS 7.x but it resulted in a
  failure when executed on RHEL/CentOS 8.x. The problem has been
  resolved by updating the code to invoke the correct OS-provided
  version of the 'tar' binary.
