Design Rationale

• React ecosystem chosen for its component-based architecture and large community support
• Node.js selected for its non-blocking I/O, making it ideal for handling multiple concurrent backups
• PostgreSQL used for its robustness in handling complex queries and relationships
• S3 chosen for its scalability, durability, and cost-effectiveness in storing large amounts of data
• Electron and React Native selected to maintain code consistency across platforms while providing native-like experiences
• JWT implemented for stateless authentication, improving scalability
• Microservices architecture adopted to allow independent scaling of different system components
