### Disaster Recovery (DR) Disaster Recovery (DR) is a set of policies, tools, and procedures to enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster, whereas alternatives like High Availability (HA) and Fault Tolerance (FT) focus on preventing downtime in the first place by implementing redundant systems and real-time data replication. In the context of web development, using frameworks like Django for the backend and React.js for the frontend, one must incorporate DR strategies, such as regular backups and failover mechanisms, to ensure that the web application remains available and functional even after a catastrophic event. Overall, incorporating Disaster Recovery in the development process is crucial for maintaining the availability, integrity, and performance of web applications, making it a key component of the larger web development picture.
