I see what you mean, i've replicated the issue in my lab using WFA 4.1 GA. The problem is that if you attempt to create a backup using the REST API:
Or if you use wfa.cmd or backup.ps1 it results in a HTTP 404 error.
PS C:\> cd '.\Program Files\NetApp\WFA\bin'
PS C:\Program Files\NetApp\WFA\bin> .\Backup.ps1 -User backup -Password ************ -Path C:\Temp\backup.zip
Exception calling "GetResponse" with "0" argument(s): "The remote server returned an error: (404) Not Found."
The backup is actually created, the issue is actually downloading the backup.
The workaround is to browse to "<%wfa_install%>jboss\standalone\deployments\download.war" and copy the file:
C:\Program Files\NetApp\WFA\bin>cd /d "C:\Program Files\NetApp\WFA\jboss\standalone\deployments\download.war"
C:\Program Files\NetApp\WFA\jboss\standalone\deployments\download.war>dir /b *.zip
You should be able to restore the .zip file to another WFA server (IE install WFA on another server, version 4.1 or 4.2) and restore the .zip file.
Note: you will need to set the wfa key on the new WFA installation (from the old WFA server) BEFORE you restore the backup
Hope that helps
