PostgreSQL backups, security and high availability

What a business should expect from PostgreSQL access controls, backups, recovery and resilient hosting. This guide explains the practical decisions behind it and what those decisions mean for the people using and operating the product.

Limit every route to the database

Private networking, firewalls and least-privilege roles reduce exposure. Applications, migrations and administrators should use separate credentials appropriate to their responsibilities.

Define recovery targets

Recovery point objectives describe acceptable data loss; recovery time objectives describe acceptable interruption. Those decisions determine backup frequency, replication and operational cost.

Test complete restoration

A green backup job does not prove the data can be recovered. Regular exercises should restore data, apply logs where used and verify that the application can reconnect and serve correct records.

Understand what replicas solve

Streaming replicas can support availability and read capacity, but replication also copies accidental changes. Independent retained backups remain essential.

Own the incident process

Alerts, escalation contacts, credentials and documented steps need periodic review. High availability is an operational capability, not a checkbox attached to the database.
