Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of comprehensive methods for troubleshooting snapshot operations, which are crucial for data backup and recovery but often fail, leading to downtime and inefficiencies in managing large digital data storage systems.
Innovation Solution
A method is developed to analyze snapshot operation data, including configuration and debug data, to identify issues and provide actionable plans for resolution, utilizing a system that locates snapshot data, assembles configuration information, performs analysis, and generates reports for users, addressing hardware, software, and network-related problems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking mechanisms are used for backing up digital data, then data integrity is ensured, but system downtime increases
Solution Approach 1:
The patent implements snapshots that capture data states in advance before failures occur, allowing immediate restoration without time-consuming backup operations during failure events. The snapshot creation happens proactively during normal operation, preparing recovery data beforehand to eliminate downtime.
Solution Approach 2:
The patent creates copy snapshots that are independent replicas of data states at specific points in time. These copies enable rapid restoration by directly utilizing the snapshot data without needing to access or lock the original data during recovery operations, thus maintaining data integrity while minimizing system downtime.
2Measurement precision
If comprehensive troubleshooting methods are implemented for snapshot operations, then diagnostic accuracy improves, but system complexity increases
Solution Approach 1:
The patent segments the troubleshooting process into distinct phases: snapshot creation phase, data collection phase, analysis phase, and resolution phase. Each phase has specific diagnostic checks and data collection activities, making the complex troubleshooting process manageable and systematic without overwhelming system complexity.
Solution Approach 2:
The patent implements automated feedback mechanisms that collect snapshot operation data, analyze it against known issues, and provide diagnostic recommendations. This feedback loop continuously improves diagnostic accuracy by learning from past snapshot operations and failures, while the automation reduces the perceived complexity for users.
3Reliability
If snapshot operations are performed frequently to ensure data availability, then data recovery capability improves, but storage resource consumption increases
Solution Approach 1:
The patent allows dynamic adjustment of snapshot parameters including retention period, snapshot frequency, and snapshot size. Users can configure snapshots to be kept for specific durations (e.g., 24 hours, 7 days) and adjust the granularity of snapshot data, enabling optimization between data recovery capability and storage resource consumption based on specific needs.
Solution Approach 2:
The patent implements automatic snapshot lifecycle management where old snapshots are discarded after their retention period expires, and storage resources are recovered for new snapshot operations. This ensures that storage resources are continuously reused rather than indefinitely consumed, maintaining data recovery capability while managing storage consumption.

AI summary
The invention pertains to a method and information handling system (IHS) for analyzing snapshot operation data of one or more snapshot operations associated with at least one storage device and at least one host computer. An embodiment of a method of the present invention begins by locating the snapshot operation data. Next, configuration information is assembled from the snapshot operation data. Further, debug data associated with the one or more snapshot operations is stored. An analysis is performed including the snapshot operation data, the configuration information, and the stored debug data. Next, the method identifies one or more issues and one or more action plans for resolution based upon the analysis. Finally, the method provides a report to one or more users including the configuration information, the one or more identified issues, and the one or more action plans.
