Backup & Disaster Recovery
Backups you have restored, recovery objectives connected to real runbooks, region failover as an operational procedure, and the capacity question failover always raises.
Schedule, retention, encryption, access and verification — the six properties that decide whether a backup is protection or a green checkmark.
The only evidence a backup works: restore it into a real target and verify the application against it. Backup success is not a signal.
A disaster is a class of event, not a size of one. DR is the standing capability to reach a known-good state, chosen per failure class.
Two business objectives that only mean something when they are traced to an architecture, a runbook and a measured drill.
Five questions decide whether a failover works: is the data there, can traffic move, is there capacity, are config and secrets present, are dependencies reachable.
Two regions is not two copies of one system. Deploys, migrations, config, secrets and data all become distributed problems you now operate every day.
Most real data loss is partial and logical. Restoring the whole database over a live system is usually the wrong tool and often makes it worse.
