2.5        Backup & Restore

It is important to backup your work. Especially when getting started.  Make a habit of it.  You can unexpectedly delete days of work in the beginning.

WebAccess has Backup and Restore functions that will backup your database, graphics, scripts and other program files to drive:\webaccess\backup folder.  This is a one click operation accessed from the first page of the project manager (the Project List).  There is a corresponding Restore function on the same page. Backup and Restore can be performed remotely from a Web Browser.

You can also copy or ZIP the WebAccess folder using ordinary Windows functions (like copy, WinZip, etc). These must be performed locally on the Project Node. To backup, copy or move a project, copy the configuration database (bwCFG.mdb) and project subdirectories to the new Project Node PC.   You can use the copy and paste feature in Windows Explorer or use WinZip or other utility. The database contains the information about tags.  The subdirectories contain the graphics, scripts and other files.

The BACKUP of the project database and subdirectories on located on the Project Node at

Drive:\WebAccess\node\Backup\bwCFGbackup.mdb

The BACKUP project subdirectories are at

Drive:\WebAccess\node\Backup\projectname_nodename

Note – The actual project database and subdirectories on located on the Project Node at

            Drive:\WebAccess\node\config\bwCFG.mdb

       The actual project subdirectories are at

         Drive:\WebAccess\node\config\projectname_nodename

If you have multiple SCADA nodes in your project, there will be a separate subdirectory for each SCADA node. 

The default database is Access 97 or Access 2000.  The bwCFG.mdb starts at around 678 Kbytes in size.  The actual size depends on how many tags are in your project.  If you add and delete tags, the database file size will only get larger. You can use the compact feature in Access 97 or 2000 to reduce the database size.   You do not need Access on your Project node in order to use WebAccess.  It is not recommended to edit the bwCFG.mdb directly.

If you run Restore before ever running Backup, you will get a blank database.
