Quickstart: Restore a database to a Managed Instance

In this quickstart, you'll use SQL Server Management Studio (SSMS) to restore a database (the Wide World Importers - Standard backup file) from Azure Blob storage into an Azure SQL Database Managed Instance.


For more information on migration using the Azure Database Migration Service (DMS), see Managed Instance migration using DMS. For more information on various migration methods, see SQL Server instance migration to Azure SQL Database Managed Instance.

Restore the database from a backup file

In SSMS, follow these steps to restore the Wide World Importers database to your Managed Instance. The database backup file is stored in a pre-configured Azure Blob storage account.

  1. Open SMSS and connect to your Managed Instance.

  2. From the left-hand menu, right-click your Managed Instance and select New Query to open a new query window.

  3. Run the following SQL script, which uses a pre-configured storage account and SAS key to create a credential in your Managed Instance.

    CREATE CREDENTIAL [https://mitutorials.blob.core.windows.net/databases]
    , SECRET = 'sv=2017-11-09&ss=bfqt&srt=sco&sp=rwdlacup&se=2028-09-06T02:52:55Z&st=2018-09-04T18:52:55Z&spr=https&sig=WOTiM%2FS4GVF%2FEEs9DGQR9Im0W%2BwndxW2CQ7%2B5fHd7Is%3D'

    create credential

  4. To check your credential, run the following script, which uses a container URL to get a backup file list.


    file list

  5. Run the following script to restore the Wide World Importers database.

    RESTORE DATABASE [Wide World Importers] FROM URL =


  6. Run the following script to track your restore's status.

    SELECT session_id as SPID, command, a.text AS Query, start_time, percent_complete
       , dateadd(second,estimated_completion_time/1000, getdate()) as estimated_completion_time
    FROM sys.dm_exec_requests r
    CROSS APPLY sys.dm_exec_sql_text(r.sql_handle) a
  7. When the restore completes, view the database in Object Explorer. You can verify that database restore is completed using sys.dm_operation_status view.


Database restore operation is asynchronous and retriable. You might get some error is SQL Server Management Studio if connection breaks or some time-out expires. Azure SQL Database will keep trying to restore database in the background, and you can track the progress of restore using the sys.dm_exec_requests and sys.dm_operation_status views. In some phases of restore process you will see unique identifier instead of actual database name in the system views. Learn about RESTORE statement behavior differences here.
