Filter Driver for Non-Standard File Path Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users may inadvertently store important data in non-standard file paths that are not covered by storage policies, leading to data loss when hardware or software failures occur, as these paths are not backed up or archived.
Innovation Solution
An information management system that includes a filter driver to monitor file system interactions, identify non-standard file paths, and alert users or automatically update the storage policy to include these paths, ensuring that critical data is backed up and archived.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If storage policy is applied to standard file paths only, then backup operation is simple and efficient, but data stored in non-standard file paths is not protected leading to data loss
Solution Approach 1:
The system performs preliminary monitoring of file system interactions to detect non-standard file paths before data loss can occur. The filter driver proactively identifies files being stored in non-standard locations and triggers alerts or automatic policy updates in advance, preventing data loss rather than responding after failure occurs.
Solution Approach 2:
The system implements feedback mechanisms where the filter driver continuously monitors file system interactions and provides real-time information about non-standard file path usage. This feedback loop enables the storage management system to detect, alert, and correct policy configurations dynamically, ensuring comprehensive data protection.
2Reliability
If storage policy is updated to include non-standard file paths, then data protection is improved, but system complexity and overhead increase
Solution Approach 1:
The system applies local quality by treating different file paths differently based on their standardization status. Standard file paths continue to be managed with existing efficient policies, while non-standard file paths receive targeted monitoring and selective policy application. This localized approach ensures comprehensive protection without uniformly increasing complexity across the entire system.
Solution Approach 2:
The system implements partial action by focusing monitoring and policy updates only on non-standard file paths that pose data loss risk, rather than redesigning the entire backup system. This selective approach addresses the critical vulnerability area without the overhead of comprehensive system redesign.
3Measurement precision
If filter driver monitors all file system interactions, then non-standard file paths are detected accurately, but system performance and resource consumption increase
Solution Approach 1:
The system extracts only the essential monitoring function from comprehensive file system analysis. The filter driver focuses specifically on detecting non-standard file path usage patterns rather than monitoring all file operations in detail. This extraction approach maintains detection accuracy for the critical issue while reducing overall resource consumption.
Solution Approach 2:
The system changes monitoring parameters to focus on specific characteristics of file path usage (standardization status, location patterns) rather than monitoring all file system interactions uniformly. This parameter specialization enables accurate detection of non-standard paths with reduced computational overhead.
Data Source
AI summary
An information management system can detect instances in which data is being stored in a non-standard file path and can alert the user of the client computing device, modify the storage policy to include the non-standard file path, and/or initiate a secondary copy operation to prevent data loss of the data stored in the non-standard file path. For example, a client computing device may execute a filter driver that monitors interactions with files in the file system. The filter driver can identify any non-standard file paths not subject to a storage policy that include files in which interactions occurred. For a non-standard file path, the filter driver can determine whether the frequency of interaction with files in the non-standard file path satisfies a threshold frequency. If the threshold is satisfied, then the filter driver may determine that the files should be subject to the storage policy and take appropriate action.
