Functional requirements of Data Backup System with non-functional

Functional Requirements

1. Backup Management
   • Backup Scheduling: Enable users to schedule automatic backups at predefined intervals (e.g., daily, weekly, monthly).
   • Backup Types: Support different types of backups, such as full, incremental, and differential backups.
   • Backup Retention: Define and manage retention policies to control how long backup data is kept before being deleted or archived.

2. Data Selection and Scope
   • Data Selection: Allow users to select specific files, directories, or entire systems to include in backups.
   • System State Backup: Provide options for backing up the entire system state, including system settings and configurations.
3. Storage Management
   • Storage Locations: Support multiple storage destinations, including local storage (e.g., disk drives), network-attached storage (NAS), and cloud storage.
   • Storage Management: Monitor and manage storage capacity, including the ability to handle low storage space and allocate resources as needed.
4. Backup Execution
   • Manual Backup: Allow users to initiate manual backups on-demand outside of scheduled times.
   • Automated Backup: Automatically execute scheduled backups without user intervention.

5. Data Restoration
   • Restoration Options: Provide options to restore data from backups, including full system restore, file-level restore, and point-in-time restore.
   • Selective Restoration: Allow users to restore specific files or directories from a backup without restoring the entire system.
6. Backup Verification
   • Integrity Checks: Perform regular checks to verify the integrity of backup data and ensure it is not corrupted or compromised.
   • Test Restorations: Allow periodic test restorations to validate that backup data can be successfully restored.
7. Security and Encryption
   • Data Encryption: Encrypt backup data both during transmission and at rest to protect against unauthorized access.
   • Access Control: Implement role-based access control to restrict access to backup and restoration functions.
8. Reporting and Alerts
   • Backup Reports: Generate reports on backup status, including success, failure, and errors.
   • Alerts and Notifications: Send alerts and notifications for backup status changes, failures, and upcoming backup schedules.
9. Audit and Compliance
   • Audit Logs: Maintain logs of backup activities, including who performed backups, what was backed up, and any issues encountered.
   • Compliance Reporting: Provide reporting tools to support compliance with industry standards and regulations (e.g., GDPR, HIPAA).
10. User Management
    • Account Management: Manage user accounts with different levels of access and permissions related to backup and restoration functions.
    • Role-Based Permissions: Implement role-based permissions to ensure users can only access and manage data appropriate to their role.

Non-Functional Requirements

1. Performance
   • Backup Speed: Ensure efficient backup performance with minimal impact on system resources and user operations.
   • Restore Speed: Provide quick data restoration times to minimize downtime in case of data loss.
2. Reliability
   • Uptime: Aim for high system availability with minimal downtime (e.g., 99.9% uptime).
   • Error Handling: Implement robust error detection and handling mechanisms to ensure system stability and data integrity.
3. Scalability
   • Capacity Handling: Design the system to scale with growing data volumes and increasing numbers of backup jobs.
   • Load Management: Ensure the system can handle peak loads and high-frequency backup operations.
4. Security

   • Access Controls: Enforce strict access controls and authentication mechanisms to prevent unauthorized access to backup data and system functions.
5. Usability
   • User Interface: Provide an intuitive and user-friendly interface for managing backup and restoration tasks.
   • Accessibility: Ensure the system is accessible to users with disabilities, complying with standards such as WCAG (Web Content Accessibility Guidelines).
6. Compatibility
   • Platform Support: Ensure compatibility with various operating systems, applications, and data formats.
   • Integration: Integrate with other systems and tools, such as enterprise resource planning (ERP) systems and databases, for comprehensive data protection.
7. Maintainability
   • Code Quality: Develop clean, well-documented code to facilitate maintenance and future updates.
   • Modular Design: Use a modular architecture to allow for easy enhancements and scalability.
8. Backup and Recovery
   • Data Backup: Implement regular automated backups to prevent data loss and ensure data integrity.
   • Disaster Recovery: Develop and test a disaster recovery plan to restore system functionality in case of major failures.
9. Support and Documentation
   • Help Desk: Provide support through helpdesk tickets, live chat, or email.
   • Documentation: Offer comprehensive user guides, system manuals, and troubleshooting documentation.
10. Data Integrity
    • Consistency Checks: Regularly verify data consistency and integrity to ensure backup accuracy.
    • Validation Rules: Implement data validation rules to prevent incorrect or incomplete data from being backed up.
