You should back up a Web server before upgrading it or making configuration changes to it. A complete Web server backup includes all Web sites, applications, and data stored on the Web server. For example, before an upgrade, or before you enable client access to a target Web server, perform a complete image backup before you change any of the configuration settings on the existing Web server. The image backup provides a point-in-time snapshot of the Web server. If unforeseen problems occur during the upgrade or configuration process, you can use this backup to restore the Web server to a known configuration.

A backup file can be saved to a hard disk, a floppy disk, or to any other nonremovable or removable media on which you can save a file. Backup files usually have the extension .bkf, but you can change it to any extension you prefer.

You should back up all boot and system volumes, including the System State, when you back up the Web server.
