From the Business Central administration center, you can export the database for Business Central online environments as .bacpac files to an Azure storage container.
Setting up Azure storage
Before you can export the file, you must first set up the Azure storage account container that the .bacpac file will be exported to.
Creating the storage account
The first step of creating the storage account container is to create the Azure storage account. To set up the export, you must first have a subscription to Microsoft Azure and access to the Azure Portal.
For more information setting up an Azure storage account, see Create a storage account.
Generating a shared access signature (SAS)
The next step is to generate a shared access signature (SAS) that provides secure delegated access to your storage account. Business Central uses this to write the .bacpac file to your storage account.
To generate a shared access signature (SAS)
On the Azure storage account, choose Shared access signature in the navigation pane.
In the Allowed services section of the shared access signature pane, select Blob, and clear the other options.
In the Allowed resource types section, select Container and Object, and clear the other options.
In the Allowed permissions section, mark Read, Write, Delete, and Create, and clear the other options.
Select a start and end date and time for the SAS. A minimum expiration window of six hours from the initiation of the export is required.
It is a best practice to use near-term expiration for the account's SAS. To reduce risk of a compromised storage account, set the end date and time no later than what is needed for you to complete the database export operation.
In the Allowed protocols section, select HTTPS only.
Select Generate SAS and connection string.
Copy the Blob service SAS URL.
For more information on generating and using a SAS, see Grant limited access to Azure Storage resources using shared access signatures (SAS).
Creating the database export
When you have created the Azure storage account and generated the SAS URI, you can then create the export file from the Business Central administration center.
- On the Environments list page, select the desired enviroment name to view the environment details.
- On the action ribbon of the environment details, choose Database, and then choose Create Database Export.
- In the File Name field, specify a name for the export file, or leave the default value.
- In the SAS URI field, specify the Blob service SAS URL value that you copied in the previous section.
- In the Container Name field, enter the name of the container in the Azure storage account to which you want the .bacpac file exported. If you have already created a container in your Azure storage account, you can enter the name of that container here. Otherwise, if the name that is specified in the Container Name field does not already exist in the Azure storage account, it will be created for you.
Once the export operation begins, the .bacpac file is generated and exported to the indicated Azure storage account. The operation may take several minutes to several hours depending on the size of the database. You can close the browser window with the Business Central administration center during the export. When the export completes, you can access the export file in the defined container in your Azure storage account.
Viewing the export history
All database export activity is logged for auditing purposes. To view the history, choose Database, and then choose View Export History on the action ribbon of the environment details page of the environment.
