Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual assessment of storage device load is performed periodically, then load balancing can be achieved, but manual errors occur and backup delays increase due to irregular assessment intervals
Solution Approach 1:
The system performs self-service through automated load monitoring and dynamic policy adjustment. The load monitoring component continuously tracks storage device utilization, and the policy adjustment component automatically modifies backup policies based on current load conditions, eliminating the need for manual assessment and reducing backup delays.
Solution Approach 2:
The system implements feedback mechanisms where load monitoring data is continuously fed back to the policy adjustment component. This closed-loop feedback enables real-time detection of storage device load changes and automatic policy modifications, ensuring regular and accurate load balancing without manual intervention.
2Device complexity
If static configuration with single storage device is used, then system complexity is reduced, but resource utilization becomes insufficient and load balancing is not achieved
Solution Approach 1:
The system transitions from static to dynamic configuration by continuously monitoring storage device load and automatically adjusting backup policies in real-time. The policy adjustment component dynamically routes backup data to storage devices based on current load conditions, optimizing resource utilization while maintaining manageable system complexity through automated control.
Solution Approach 2:
The backup system achieves multi-functionality by enabling a single backup source to utilize multiple storage devices dynamically. The load monitoring and policy adjustment components work together to distribute backup data across multiple storage devices based on their current capacity and load, maximizing resource utilization without requiring complex manual configuration for each device.
3Device complexity
If all backup data is routed to a single storage device, then configuration is simplified, but unbalanced load occurs and backup window increases
Solution Approach 1:
The system dynamically adjusts data routing based on real-time storage device load monitoring. The policy adjustment component continuously modifies backup policies to distribute data across multiple storage devices according to their current capacity and utilization, preventing load imbalance and reducing backup window duration without requiring complex manual routing configuration.
Solution Approach 2:
The load monitoring component provides continuous feedback on storage device utilization to the policy adjustment component. This feedback mechanism enables automatic detection of load imbalances and real-time policy modifications to distribute backup data across multiple storage devices, preventing extended backup windows while maintaining simplified configuration through automated control.
4Ease of operation
If manual realignment is performed when new load is added, then load balancing can be maintained, but higher manual efforts are required and backup operations are delayed
Solution Approach 1:
The system performs self-service by automatically detecting new backup data loads and realigning them across storage devices. The load monitoring component identifies new load patterns, and the policy adjustment component automatically modifies backup policies to distribute the new load appropriately, eliminating manual realignment efforts and preventing backup operation delays.
Solution Approach 2:
The system implements feedback loops where load monitoring continuously tracks storage device utilization and new backup data patterns. This feedback enables the policy adjustment component to automatically realign backup operations when new loads are added, maintaining load balancing without manual intervention and ensuring continuous backup operation speed.

AI summary
The present disclosure is related to field of data backup in storage environment, and a method and system for dynamically controlling backup data on storage devices. A data allocating system may pool storage devices and backup data corresponding to client devices. Further performance parameters of storage devices may be evaluated for a pre-set time period based on which a rank is assigned to each of the plurality of storage devices based on performance parameters. Upon assigning the rank, the load characteristics and performance characteristics may be evaluated for each client device for the pre-set time period based on which a performance load index is determined for each client device. Finally, backup data of each client device may be dynamically allocated to each storage device by correlating rank and performance load index. The present disclosure reduces load on single storage device and increases efficiency by reducing delay in backing up data.
