Data Restoration via Local-Remote Storage Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for restoring data in degraded computer systems are costly, result in significant downtime, and risk loss of data due to various failure points such as inaccessible storage devices, power supply faults, and system malfunctions.
Innovation Solution
A method and system that stores user data locally on a hard disk drive and an internal data storage device, with the option to copy a subset of this data to a remote storage device upon system performance degradation, using an alternate operating system if necessary, and restore it once the system is repaired, utilizing direct data connections like USB or peer-to-peer connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored only on local hard disk drive, then data accessibility is fast, but data loss risk increases during system degradation
Solution Approach 1:
The system automatically copies data to remote storage devices before system failures occur by monitoring performance degradation indicators. This preliminary action ensures data is backed up in advance, preventing data loss when failures happen.
Solution Approach 2:
The patent implements redundant data storage across multiple locations (local hard drive, internal storage device, and remote storage devices) to cushion against potential failures. This redundancy acts as a buffer that protects data even when primary storage fails.
2Reliability
If periodic backup copies are made to remote storage, then data safety improves, but downtime and productivity loss increase
Solution Approach 1:
The system performs automatic self-service backup operations by monitoring its own performance degradation and initiating data copies to remote storage without requiring user intervention. This eliminates the need for manual backup operations that would cause downtime.
Solution Approach 2:
The patent enables continuous data protection by automatically copying data during system operation rather than requiring system shutdown for backups. The useful action of data copying continues without interrupting normal system functionality.
3Speed
If direct data access is performed from external systems, then data recovery speed increases, but system complexity and cost increase
Solution Approach 1:
The patent uses an intermediary approach where data is first copied to remote storage devices during normal operation, which then serve as intermediaries for data recovery. This reduces the complexity of direct access operations while maintaining fast recovery speeds through pre-positioned data copies.
4Reliability
If multiple backup storage devices are used, then data redundancy improves, but device complexity and cost increase
Solution Approach 1:
The patent segments data storage across multiple independent locations (local hard disk drive, internal storage device, and remote storage devices). This segmentation provides redundancy while keeping each individual component relatively simple, avoiding the complexity of a single complex backup system.

AI summary
Methods and systems for restoring data in a degraded computer system are presented. In an embodiment, a method includes storing user data to a hard disk drive that is local to a user interface device. The method may also include storing a sub-set of the user data to a internal data storage device that is local to the user interface device. Additionally, the method may include copying the sub-set of the user data from the internal data storage device to a remote data storage device in response to a degradation of system performance of the user interface device. In an embodiment, the data may be retrieved from the internal data storage by an external system, even when the user interface device is in a degraded or unresponsive state.
