Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data recovery processes rely on manual inspections, which are time-consuming and prone to inaccuracies, leading to the potential inclusion of incorrect media in data recovery jobs, resulting in wasted time and resources.
Innovation Solution
An automated system and method that detects and prevents incorrect media from being part of a data recovery job by using physical characteristics, media type and format validation, media pool membership verification, and content fingerprinting to ensure media accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection is used to detect incorrect media, then media accuracy can be improved, but processing time and labor costs increase significantly
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated optical scanning system that uses barcode readers and RFID scanners to detect media identifiers. This substitution eliminates human labor while maintaining high detection accuracy and significantly reduces processing time through automated comparison algorithms.
Solution Approach 2:
The system enables self-service by allowing the media verification process to occur automatically without human intervention. The automated scanning system reads media identifiers, compares them against the job manifest database, and flags discrepancies independently, freeing human operators from tedious manual checking while maintaining reliability.
2Measurement precision
If every media label is manually checked against a master list, then detection precision can be improved, but productivity decreases
Solution Approach 1:
The system performs preliminary action by pre-loading the job manifest database with all expected media identifiers before the verification process begins. This allows the automated scanning system to quickly compare each media item against the pre-prepared list, maintaining high detection precision while enabling rapid processing of large volumes of media without sequential human checking.
Solution Approach 2:
The patent uses copying by creating a digital replica of the master media list in the form of a database manifest. The automated system reads this copied version and compares it against physical media identifiers, eliminating the need for manual cross-referencing while maintaining detection precision and significantly increasing processing speed.
3Productivity
If automated detection systems are implemented, then processing speed and productivity are improved, but system complexity increases
Solution Approach 1:
The patent applies universality by designing a multi-functional automated verification system that can handle multiple media types (tapes, discs, removable storage), various identification methods (barcodes, RFID tags, printed labels), and different verification modes. This consolidation of multiple functions into a single system improves processing speed while managing complexity through standardized interfaces and protocols.
Data Source
AI summary
Disclosed are embodiments of a system and method for detecting wrong storage media in data recovery processes. One embodiment can detect incorrect media via environmental factors such as source data type and format. One embodiment can detect incongruous media by pool membership. One embodiment can detect inappropriate media by comparing fingerprints. As each item is read, its fingerprint is calculated and compared to the overall fingerprint of a job. If the new fingerprint is different by some preset margin, a human inspector may be asked to validate the newly inserted storage medium. If valid, the overall signature for the job is revised to integrate the new signature. If not, the wrong medium is ejected and incorrectly loaded data is removed. Embodiments disclosed herein can detect the presence of a wrong medium quickly and early in a data recovery process, avoiding mistakes and saving time and costs.
