DM/2 WPS IMAGE BACKUP:

This facility is provided to ensure the user a way to completely restore the Workplace Shell Desktop as it is currently configured.  It does take some time, depending on the size of the hard disk.  However, it is recommended to use this option on at least the initial installation of the product.

Workplace Shell Image Backup option defaults to Yes, the first time you install.  If you change the selection to No, then that will be the future default option.

The backup is performed only if one or more components are being installed.  For the Refresh, Uninstall and Remove options, this setting is ignored, so the user can leave it set to Yes, and have it active only on installs and upgrades.
