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.
- 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.
