Applies to: Azure SQL Managed Instance

This PowerShell script example restores an Azure SQL Managed Instance database from a remote geo-region (geo-restore).

If you don't have an Azure subscription, create an Azure free account before you begin.

Note

This article uses the Azure Az PowerShell module, which is the recommended PowerShell module for interacting with Azure. To get started with the Az PowerShell module, see Install Azure PowerShell. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.

Use Azure Cloud Shell

Azure hosts Azure Cloud Shell, an interactive shell environment that you can use through your browser. You can use either Bash or PowerShell with Cloud Shell to work with Azure services. You can use the Cloud Shell preinstalled commands to run the code in this article, without having to install anything on your local environment.

To start Azure Cloud Shell:

Option	Example/Link
Select Try It in the upper-right corner of a code block. Selecting Try It doesn't automatically copy the code to Cloud Shell.
Go to https://shell.azure.com, or select the Launch Cloud Shell button to open Cloud Shell in your browser.
Select the Cloud Shell button on the menu bar at the upper right in the Azure portal.

To run the code in this article in Azure Cloud Shell:

Start Cloud Shell.
Select the Copy button on a code block to copy the code.
Paste the code into the Cloud Shell session by selecting Ctrl+Shift+V on Windows and Linux, or by selecting Cmd+Shift+V on macOS.
Select Enter to run the code.

If you choose to install and use PowerShell locally, this tutorial requires Azure PowerShell 1.4.0 or later. If you need to upgrade, see Install Azure PowerShell module. If you are running PowerShell locally, you also need to run Connect-AzAccount to create a connection with Azure.

Sample script

# Connect-AzAccount
# The SubscriptionId in which to create these objects
$SubscriptionId = '<put subscription_id here>'
# Set the information for your managed instance
$SourceResourceGroupName = "myResourceGroup-$(Get-Random)"
$SourceInstanceName = "myManagedInstance-$(Get-Random)"
$SourceDatabaseName = "myInstanceDatabase-$(Get-Random)"

# Set the information for your destination managed instance
$TargetResourceGroupName = "myTargetResourceGroup-$(Get-Random)"
$TargetInstanceName = "myTargetManagedInstance-$(Get-Random)"
$TargetDatabaseName = "myTargetInstanceDatabase-$(Get-Random)"

Connect-AzAccount
Set-AzContext -SubscriptionId $SubscriptionId

$backup = Get-AzSqlInstanceDatabaseGeoBackup `
-ResourceGroupName $SourceResourceGroupName `
-InstanceName $SourceInstanceName `
-Name $SourceDatabaseName

$backup | Restore-AzSqlInstanceDatabase -FromGeoBackup `
-TargetInstanceDatabaseName $TargetDatabaseName `
-TargetInstanceName $TargetInstanceName `
-TargetResourceGroupName $TargetResourceGroupName

Clean up deployment

Use the following command to remove the resource group and all resources associated with it.

Remove-AzResourceGroup -ResourceGroupName $TargetResourceGroupName
