Is is possible to replicate Azure SQL Backups to a external cloud

I have configured backups for my Azure SQL database and I'm interested in replicating the LTR backups to an external cloud like AWS or GCP. For example, if I can configure Azure to place the LTR backups into a storage account, then I could build the replication logic. But as it stands, I can't seem to find any way to access my own backups - other than restoring them into a new Azure DB.

    Accessing LTR (Long-Term Retention) backups for Azure SQL Database directly isn't supported, as Azure manages these backups internally. However, there are a few strategies you can consider for replicating your Azure SQL Database backups to AWS or GCP:

    Custom Backup Solution: Implement a custom backup solution using tools like SQL Server Management Studio (SSMS) or Azure Automation to perform regular exports of your database to a .bacpac file. Store these files in an Azure Storage Account, from where they can be copied to AWS S3 or GCP Storage.

    Azure Data Factory: Use Azure Data Factory to create a pipeline that exports data from Azure SQL Database to Azure Blob Storage. From there, you can set up a process to transfer the data to AWS or GCP.

    1. Database Export via PowerShell: Use Azure PowerShell to automate the export of your database to a .bacpac file, which can then be transferred to other cloud storage solutions.

    Here’s a sample PowerShell script to export an Azure SQL Database to a .bacpac file:

    # Define parameters
    $subscriptionId = "<your_subscription_id>"
    $resourceGroupName = "<your_resource_group_name>"
    $serverName = "<your_sql_server_name>"
    $databaseName = "<your_database_name>"
    $storageAccountName = "<your_storage_account_name>"
    $storageContainerName = "<your_storage_container_name>"
    $bacpacFileName = "<your_bacpac_file_name>.bacpac"
    # Login to Azure
    Connect-AzAccount
    Set-AzContext -SubscriptionId $subscriptionId
    # Export database to bacpac file
    New-AzSqlDatabaseExport -ResourceGroupName $resourceGroupName -ServerName $serverName -DatabaseName $databaseName -StorageKeyType "StorageAccessKey" -StorageKey "<your_storage_account_key>" -StorageUri "https://$storageAccountName.blob.core.windows.net/$storageContainerName/$bacpacFileName" -AdministratorLogin "<your_admin_login>" -AdministratorLoginPassword (ConvertTo-SecureString "<your_password>" -AsPlainText -Force)
    

    After exporting the .bacpac file to Azure Blob Storage, you can configure cross-cloud replication using tools like AWS DataSync or GCP Transfer Service.
