You will be able to backup your SMS on your Phone using the Sony Ericsson PC Suite. But you will not be able to move the messages back to your phone from the computer. So you just keep the backup of the SMS on your computer only.
Please take note that you must use Phone Mode for Connections. This allowed the PC Suite to access all Phone Contents.
Click on Text Messages on the left side bar. You will be able to access all your sms on your phone.
