Disaster Recovery¶

Any event that has a negative impact on a company's business continuity or finances is a disaster
Disaster recovery (DR) is about preparing for and recovering from a disaster
What kind of disaster recovery?
- On-premise => On-premise: traditional DR, and very expensive
- On-premise => AWS Cloud: [[hybrid recovery]]
- AWS Cloud Region A => AWS Cloud Region B
Need to define two terms:
- RPO : [[Recovery Point Objective]]
- RTO : [[Recovery Time Objective]]
