Export SQL Server Database to BACPAC File

Understanding BACPAC Export

A BACPAC file encapsulates SQL Server database metadata and data into a single ZIP file with a .bacpac extension. This file can be stored either in Azure Blob storage or on local storage. BACPACs are designed for moving databases between SQL Server and Azure SQL services, including Azure SQL Database and Azure SQL Managed Instance.

Prerequisites for Export

Ensure transactional consistency by avoiding write activity during the export process. Transactional consistency is crucial for maintaining the integrity of the exported data. The export must be performed from a transactionally consistent copy of the database.

Export Limitations

The maximum size for a BACPAC file is 200 GB. Export operations exceeding 20 hours may be canceled. BACPAC export is unsuitable for traditional backup and restore operations and is not supported to premium storage, storage with a firewall, immutable storage, or when using MFA with Azure's Import/Export service.

Export Procedure

Use the Azure PowerShell cmdlet New-AzSqlDatabaseExport to initiate an export request. Monitor the status with Get-AzSqlDatabaseImportExportStatus and cancel if needed using Stop-AzSqlDatabaseActivity. Note that exporting to a BACPAC file on an Azure SQL Managed Instance using Azure PowerShell or the Azure portal is not supported.

File Naming Conventions

The filename for the BACPAC file should be under 128 characters and must not end with a period or include special characters like space, , >, *, %, &, :, , /, or ?. Adhering to these rules prevents issues during storage and retrieval.

Considerations for Large Databases

For larger databases, BACPAC export/import operations may be time-consuming and are prone to failure. In such cases, using SQLPackage for import/export is recommended to enhance reliability and performance.

Frequently Asked Questions

What is a BACPAC file?

A BACPAC file is a ZIP file with an extension of BACPAC that contains the metadata and data from the database.

What is the purpose of exporting a database to a BACPAC file?

Exporting a database to a BACPAC file is useful for archiving or for moving the database to another platform.

Can I use a BACPAC file for backup and restore operations?

BACPAC exports are not intended to be used for backup or restore operations.

How do I export a SQL Server database to a BACPAC file using SSMS?

In SSMS, connect to the SQL Server instance, right-click on the desired database, select Tasks, select Export Data-tier Application, and follow the wizard to save the BACPAC file to the local disk or to Microsoft Azure.

Are there any limitations on where I can export a BACPAC file?

Yes, exporting a BACPAC file to Azure premium storage, storage behind a firewall, or immutable storage is not supported.
