The number of nodes will vary based on the target capacity and performance requirements. See Scalability Considerations for detailed scaling guidance.
2. Performance Characteristics
Performance testing was conducted using a combination of synthetic benchmarks and real-world backup/restore scenarios. The testing environment included a network with low latency and sufficient bandwidth. See Testing Methodology for complete details on testing procedures.
- Backup Performance (Initial Full Backup): Approximately 400 MB/s per node for initial full backups of diverse datasets (documents, images, videos, databases). This rate is impacted by network bandwidth and data compression ratios employed by the backup software. See Data Compression Techniques for details on compression algorithms.
- Backup Performance (Incremental Backup): Up to 1 GB/s per node for incremental backups, depending on the amount of changed data. Incremental backups are significantly faster due to the reduced data transfer volume.
- Restore Performance (Full Restore): Approximately 600 MB/s per node for full restores. Restore speeds are often faster than backup speeds due to the ability to stripe data across multiple drives.
- Restore Performance (File-Level Restore): File-level restores exhibit variable performance, averaging 200-300 MB/s per node, dependent on file size and metadata lookup efficiency.
- IOPS (Random Read/Write): The NVMe SSDs used for metadata achieve approximately 500,000 IOPS, ensuring fast catalog access and efficient backup/restore operations. See Metadata Management for information on metadata structure.
- CPU Utilization (Backup): During backup operations, CPU utilization typically ranges from 60-80%, primarily attributed to data compression and encryption.
- CPU Utilization (Restore): During restore operations, CPU utilization is typically lower, ranging from 40-60%.
- Network Utilization (Backup/Restore): Network utilization consistently reached the 100GbE limit during peak backup and restore operations, demonstrating the effectiveness of the network infrastructure. See Network Infrastructure Requirements for details.
The following table summarizes benchmark results compared to a previous generation configuration:
| Metric | Cloud Backups (Current) | Previous Generation | Improvement |
|---|---|---|---|
| Full Backup Speed (MB/s) | 400 | 250 | 60% |
| Incremental Backup Speed (MB/s) | 1000 | 600 | 67% |
| Full Restore Speed (MB/s) | 600 | 400 | 50% |
| File-Level Restore Speed (MB/s) | 250 | 150 | 67% |
| Metadata IOPS | 500,000 | 100,000 | 400% |

5. Maintenance Considerations
Maintaining the "Cloud Backups" infrastructure requires careful planning and adherence to best practices.
- Cooling: The 4U chassis and high-density storage configuration generate significant heat. Adequate cooling is crucial. Maintain a datacenter temperature of 20-24°C (68-75°F) and ensure proper airflow through the server racks. Regularly inspect and clean cooling fans. See Datacenter Cooling Best Practices.
- Power: Each node requires approximately 1200-1500W of power. Ensure sufficient power capacity in the datacenter and utilize redundant power supplies for high availability. Implement power monitoring to detect and address potential issues. See Power Distribution Units (PDUs).
- Storage: Regularly monitor the health of the hard drives using SMART (Self-Monitoring, Analysis and Reporting Technology) data. Replace failing drives proactively to prevent data loss. Implement a regular drive replacement schedule (e.g., every 3-5 years) to maintain data integrity. See Storage Health Monitoring.
- RAID Maintenance: Monitor the RAID controller and BBU for errors. Ensure the RAID array is properly configured and functioning. Test the RAID failover process periodically.
- Network: Monitor network performance and identify potential bottlenecks. Ensure the 100GbE network infrastructure is properly configured and maintained. See Network Monitoring Tools.
- Software Updates: Regularly update the operating system, firmware, and backup software to address security vulnerabilities and improve performance. Implement a robust patch management process. See Server Security Best Practices.
- Backup Software Configuration: Regularly review and optimize the backup software configuration to ensure efficient backup and restore operations. Monitor backup job logs for errors. See Backup Software Configuration.
- Data Integrity Checks: Periodically perform data integrity checks to verify the consistency and accuracy of the backed-up data. Use checksums or other data verification methods. See Data Validation Techniques.
