Retirement: Azure App Service Will No Longer Support Linked Databases as a Part of Custom Backups After March 31, 2028

Beginning March 31, 2028, the Azure App Service custom backup feature will no longer back up linked databases configured as part of the Azure App Service custom backup feature**.** We strongly recommend that you use the native backup and restore tools available with the respective databases, instead. Before March 31, 2028, the App Service team will remove the ability to include linked databases as part of new custom backup configurations for App Service web applications. The schedule for this change is as follows: * November 2025 for linked MySQL and PostgreSQL databases * April 2026 for linked Azure SQL and SQL Server databases App Service web applications with existing custom backups that already include linked databases will continue to back up the linked databases until retirement of the App Service custom backup linked database feature on March 31, 2028. ### Recommended action To avoid data or functionality loss, implement backup strategies for databases linked to your App Service web applications by 31 March 2028\.
