Restoring SQL Server backup to Azure SQL Database

Is there a way to simply take a SQL backup .bak file, and using that as a restore point to generate a new database on Azure SQL Database?

The wizard that I see generally recommended in this situation wants to create a custom file to use, but it pukes on the encrypted objects ( functions and views ) and I don't see another way to get it going.

回答1:

If you already have a database on local machine then you can migrate it directly on Azure using SQL Management Studio. Follow these steps:

Right click on the database name in SSMS:

Follow the wizard that appears then.

If you're running SSMS v17 you can configure the Azure SQL database edition, size and service objective.

回答2:

Azure SQL Database does not currently support that functionality. The only method to restore in Azure SQL Database is import from BACPAC files - you can migrate to Azure SQL DB using BACPAC files by following this guide: https://azure.microsoft.com/en-us/documentation/articles/sql-database-cloud-migrate/

The other options is to use SQL Server in a VM, which would enable a restore of a .bak file

Currently Azure doesn't support restoring the database on Azure SQL Instance using the backup (.bak) file. But there are many other ways to migrate the SQL Database to Azure SQL. For Example, using the SQL Server Management Studio deploy mention or by taking the backup in the .bacpac file and then importing it using SSMS Export/Import or using the Microsoft database migration assistance tool. Below link will be useful to you as they explain these ways as step by step process.

To get my .BAK file on Azure SQL Server, I followed the advice of both answers in this thread.

Before completing the below steps the BAK file restore failed on my laptop SQL instance (the backups were from SQL2016 and not compatible with my SQL2014). I was working on training from EDX.org: “DAT216x Delivering a Relational Data Warehouse” and I had downloaded these two files from the training: AdventureWorks2016CTP3.bak and AdventureWorksDW2016CTP3.bak.

BAK to AzureDB

I followed these 2 videos (hosted on YouTube) to create the Azure VM and SQL Instance to be used in MCA training… Demo: Provisioning Microsoft Azure Services (VM, SQL). The 9:00-minute video shows you how to provision the relevant Azure resources. The video also demonstrates how to get the connection string for the Azure SQL Database, which is used in the next step.

From the Azure VM remote session connection to SSMS I did the Restore Database from BAK.

USER: razon | ANSWER: Right click (database name) > Tasks > Deploy Database to SQL Azure…

From the Azure VM remote sessions connection to SSMS SQL Instance, I ran the wizard “Deploy Database to SQL Azure”. After connection successfully the deployment took a few minutes to complete. NOTE: you must use ‘SQL Server Authentication’ because ‘Windows’ is not supported for Azure database. The Azure SQL Server authentication was demonstrated in the video link provided earlier in this answer.
