PostgreSQL servers should have geo-redundant backup enabled
Azure Database for PostgreSQL allows you to choose the redundancy option for your database server. It can be set to a geo-redundant backup storage, replicated to a paired region. Configuring geo-redundant storage for backup is only allowed during server create.
The data is not only stored within the region in which your server is hosted, but is also replicated to a paired region to provide recovery option in case of a region failure.
What this control checks
PostgreSQL server geoRedundantBackup must be Enabled; any other value fails.
Common pitfalls
Geo-redundant storage only allowed during server create
Configuring geo-redundant storage for backup is only allowed during server create.
Audit evidence
Evidence that deployed resources meet this control: Azure Policy compliance results for the built-in policy definition "Geo-redundant backup should be enabled for Azure Database for PostgreSQL" (48af4db5-9b8b-401c-8e74-076be876a430); PowerPipe control azure_compliance.control.postgres_db_server_geo_redundant_backup_enabled.
Scans of the Terraform code that flag the same setting before deployment: Checkov check CKV_AZURE_102; KICS query "Geo Redundancy Is Disabled" (8b042c30-e441-453f-b162-7696982ebc58).
