将 Azure 托管实例数据库备份导出到存储帐户

Question

I am looking for an alternative to :

New-AzureRmSqlDatabaseExport

For the purpose of taking Managed Instance Database backup and export it to storage account. The above command, I think supports only SQL Server.

Answer 1

Yes, your're right, Powershell command doesn't support export the Azure SQL managed instance for now, you could reference this document: Export to a BACPAC file using PowerShell :

Besides, the document also gives the other ways:

Exporting a BACPAC of a database from a managed instance using Azure PowerShell is not currently supported. Use SQL Server Management Studio or SQLPackage instead.

1. Export to a BACPAC file using the SQLPackage utility
2. Export to a BACPAC file using SQL Server Management Studio (SSMS)

At least, you also can use T-SQL to backup the Azure SQL manage instance to Blob Storage:

First, you would need to store credentials that would be used to access Azure Blob Storage:

CREATE CREDENTIAL [https://myacc.blob.core.windows.net/testcontainer] 
WITH IDENTITY='SHARED ACCESS SIGNATURE' 
, SECRET = 'sv=2014-02-14&sr=c&sig=GV0T9y%2B9%2F9%2FLEIipmuVee3jvYj4WpvBblo%3D&se=2019-06-01T00%2A%3AZ&sp=rwdl';

Once you create a credential, you can backup any database using standard BACKUP T-SQL command:

BACKUP DATABASE tpcc2501 
TO URL = 'https://myacc.blob.core.windows.net/testcontainer/tpcc2501.bak' 
WITH COPY_ONLY 

Reference this Azure blog: Native database backup in Azure SQL Managed Instance .

Hope this helps.
