Restore a web app from a backup in another subscription using PowerShell
This sample script retrieves a previously completed backup from an existing web app and restores it to a web app in another subscription.
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.
We recommend that you use the Azure Az PowerShell module to interact with Azure. See Install Azure PowerShell to get started. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.
