Azure SQL Database's default 7-day backup retention is a compliance trap that catches teams off guard during audits and outages. The post walks through the four failure modes of default configurations, then provides Bicep templates for short-term retention (35 days), long-term retention (up to 7 years), and geo-replication. It also covers point-in-time restore procedures via Azure CLI, a GitHub Actions workflow for automated monthly restore validation, and an ASP.NET Core health check that monitors EarliestRestoreDate, geo-redundancy, and TDE status. Real production incident examples illustrate the consequences of untested backups, hardcoded connection strings after failover, and missing TDE on restored databases. The core message: backups without verified restores are just expensive storage.
