Disaster Recovery
Also written as DR, Business Continuity
A team's planned process for restoring systems and data after a major failure (a data center outage, data corruption, a botched deployment) — including how much data loss and downtime is acceptable.
Think of it like
Like a building's fire escape plan — you hope to never use it, but the time to figure it out isn't in the middle of an actual fire.
Junior or senior?
Junior sounds like
Has a disaster recovery document that's never been exercised.
Senior sounds like
Has actually tested it — a real or simulated failover — and can describe what the test revealed.
Ask them
“Has your team ever actually tested a disaster recovery plan — a real or simulated failover? What did the test reveal?”
