Triplex Removable Media Archiving for Long-Term Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of managing and archiving vast quantities of digital data across multiple removable digital storage media devices over long periods, such as years or decades, while minimizing data loss and ensuring data integrity and cost-effectiveness, is not adequately addressed by existing technologies.
Innovation Solution
A triplex data structure system comprising a collection of removable digital storage media devices, a physical library manager, a meta-database, and an orchestration engine that manages near-line and off-line media, along with methods for data movement and virtualization, providing a cohesive file system interface that aggregates and secures data across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored across multiple removable digital storage media devices, then storage capacity and data security are improved, but system complexity and difficulty of management increase
Solution Approach 1:
The patent divides the storage system into multiple independent removable digital storage media devices, each capable of storing portions of the dataset. This segmentation allows data to be distributed across multiple physical devices, improving security and reliability while maintaining individual device simplicity.
Solution Approach 2:
The patent introduces a file system and metadata structure that acts as an intermediary between the user and the distributed storage devices. This intermediary layer manages the complexity of cross-device data organization, allowing users to access data through a unified interface without directly managing the underlying distributed architecture.
2Duration of action of stationary object
If data is archived for long periods (years or decades), then data preservation is improved, but risk of data loss from degradation or catastrophic failure increases
Solution Approach 1:
The patent implements different quality levels for different portions of data by creating multiple copies (essences) of critical data across separate devices. This ensures that even if one device degrades or fails over long periods, other devices contain intact copies, maintaining data integrity throughout the extended storage duration.
Solution Approach 2:
The patent preemptively addresses long-term storage risks by distributing data across multiple devices and maintaining redundant copies before any failure occurs. This cushioning approach ensures that degradation or catastrophic failure of individual devices does not result in data loss, as other devices contain protective copies.
3Reliability
If redundant metadata and file essences are maintained across multiple devices, then data integrity is improved, but storage space requirements increase
Solution Approach 1:
The patent creates copies of file essences and metadata across multiple devices, but uses intelligent distribution strategies to minimize total storage requirements. By strategically placing redundant copies only where necessary to ensure integrity, the system maintains data integrity while optimizing storage space utilization.

AI summary
Embodiments described herein provide systems and methods that allow for the archiving of computer data and computer files by aggregating archival content on various types of Removable Digital Storage Media. The system that supports the archiving is a triplex data structuring system providing at least three separate data pools working in synchrony for the stability of the data. Various methods are described to write data, to read data, to virtualize the data, to store data chronologically, to aggregate small files, to screen for malware, and to create various modes of redundancy that allow for the reconstruction of the system even after catastrophic failures.
