20.2Backup & Restore

WebAccess has  Backup and Restore functions that will backup you database, graphics, scripts and other program files to 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 on the same page.

You can also copy or ZIP the WebAccess folder using ordinary Windows functions (like copy, WinZip,. etc). 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.

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.

Web Access also provides a backup function. 

The Backup and Restore files are created on the Project Node , although they can be executed remotely.
