17.1 Creating a Backup

Although VTS automatically saves your changes as you work, it is important to keep in mind that a system crash or power outage could jeopardize your applications and your data. It is therefore highly recommended that you save a copy of your work on a regular basis.

1.  Stop the application.

VTS automatically saves your work and releases locks on open files.

2.  Click the Properties button.

Before making a backup, you need to know what directory the application is in.  You also need to know if this application is based on another layer so that that application can also be saved.

The Path is shown at the top right corner of the dialog. This path is relative to your VTS installation (C:\VTS\Tutorial\)

 

In the Status area of the Application Properties dialog, "Tutorial Simulated I/O" appears. As you may remember, this was the application type we chose when we created the tutorial application.

As you may remember, "Tutorial Simulated I/O" is actually the name of an application upon which our tutorial application has been based.

 

Applications that are layered on top of other applications inherit and use the functionality of those applications. Therefore, when you are backing up files, you must also back up all application layers in order for the application to work.

 

Because the "Tutorial" application is based on the "Tutorial Simulated I/O" application, you must back up both applications.

 

3.  Using Windows Explorer (or the file management utility of your choice), open the VTS installation directory.

4.  Locate the "TutSim" application directory within the VTS installation directory.

5.  Copy the "TutSim" application directory to your backup device.

6.  Locate the "Tutorial" application directory within the VTS installation directory.

7.  Copy the "Tutorial" application directory to your backup device.

You have now successfully created a backup all of the directories and files necessary to the operation of your tutorial application.

 

More detailed information on the architecture of VTS and layered applications can be found in your VTS Developer's Guide.
