Back up a web app using PowerShell

This sample script creates a web app in App Service with its related resources, and then creates a one-time backup for it.

If needed, install the Azure PowerShell using the instruction found in the Azure PowerShell guide, and then run Connect-AzAccount to create a connection with Azure.
