Backup Schedule Assignment for Unpredictable Data Growth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backup systems struggle to create appropriate schedules when the capacity of backup data is difficult to predict, leading to incomplete backup processes within the designated backup window.
Innovation Solution
A backup schedule creation device that calculates predicted backup times based on estimated throughput and used capacity, and assigns backup processes to data transfer servers to optimize network usage, creating a backup schedule that accounts for changes in data capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a preset combination of data transfer server and backup target machine is used, then the system structure is simple, but the backup process cannot complete within the backup window when backup data rapidly increases
Solution Approach 1:
The patent implements dynamic schedule creation by calculating predicted backup times based on estimated throughput and used capacity, then sequentially assigning backup processes to data transfer servers. This dynamic assignment allows the system to adapt to rapidly changing backup data volumes and complete backups within the backup window, resolving the contradiction between backup completion speed and schedule management complexity.
2Productivity
If the number of data transfer servers is increased to handle larger backup data, then backup throughput improves, but system cost and complexity increase
Solution Approach 1:
The patent changes the parameter of backup time prediction by calculating predicted backup times based on estimated throughput and used capacity. This allows the system to optimize the utilization of existing data transfer servers through intelligent schedule creation, achieving high backup throughput without necessarily increasing the number of servers, thus resolving the contradiction between backup throughput and server quantity.
3Ease of operation
If backup schedules are created without considering network usage, then schedule creation is simple, but network congestion occurs during backup execution
Solution Approach 1:
The patent incorporates network usage feedback into the schedule creation process by sequentially assigning backup processes based on predicted backup time and network usage information. This feedback mechanism allows the system to create schedules that account for network conditions, preventing congestion and ensuring reliable network performance during backup execution, while maintaining relatively simple schedule creation through automated assignment.
