Restore a web app from a backup using Azure PowerShell

This sample script retrieves a previously completed backup from an existing web app and restores it by overwriting its content.

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.

Sample script

Note

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.

$resourceGroupName = "myResourceGroup"
$webappname = "<replace-with-your-app-name>"
$targetResourceGroupName = "myResourceGroup"
$targetWebappName = "<replace-with-your-app-name>"

# List statuses of all backups that are complete or currently executing.
Get-AzWebAppBackupList -ResourceGroupName $resourceGroupName -Name $webappname

# Note the BackupID property of the backup you want to restore

# Get the backup object that you want to restore by specifying the BackupID
$backup = (Get-AzWebAppBackup -ResourceGroupName $resourceGroupName -Name $webappname -BackupId '<replace-with-BackupID>')

# Get the storage account URL of the backup configuration
$url = (Get-AzWebAppBackupConfiguration -ResourceGroupName $resourceGroupName -Name $webappname).StorageAccountUrl

# Restore the app by overwriting it with the backup data
Restore-AzWebAppBackup -ResourceGroupName $resourceGroupName -Name $webappname -StorageAccountUrl $url -BlobName $backup.BlobName -Overwrite

Clean up deployment

If you don't need the web app anymore, use the following command to remove the resource group, web app, and all related resources.

Remove-AzResourceGroup -Name $resourceGroupName -Force
