Design a Cloud-Based Backup Solution

Functional Requirements

• Users can schedule automatic backups for their data.
• Support for full and incremental backups to optimize storage and bandwidth.
• Users can restore data from any backup point.
• Data is encrypted both during transfer and at rest.
• Users can manage backup settings (e.g., schedule, retention period).
• Access control: Only authorized users can access or restore their data.

Non-Functional Requirements

• High reliability: Backups must not be lost and restores should be successful.
• Scalability: System should handle increasing number of users and data volume.
• Security: Strong encryption and secure authentication mechanisms.
• Performance: Backups and restores should complete in a reasonable time.
• Usability: Simple user interface for managing backups and restores.
• Cost-effective: Optimize storage and network usage to control costs.
• Compliance: Ability to meet common data protection regulations (e.g., GDPR).
• Auditability: Maintain logs of backup and restore actions for tracking and compliance.
