Solution Overview

Problem

Traditional file backup methods are inefficient and inconvenient, particularly in modern file systems, as they mix all file types into one backup session, leading to slow recovery processes and downgraded deduplication rates, making it difficult for users to recover specific file types and resulting in a poor user experience.

Innovation Solution

The method involves dividing files into subsets by type, generating separate backup files for each type, and creating an overall backup file, allowing for parallel processing and improved deduplication, thereby simplifying file recovery and enhancing performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If all files are backed up together in one backup session, then the backup process is simple to implement, but the backup time is long and recovery efficiency is poor

Engineering Contradiction:
Improvesimplicity of backup implementationVSAvoidbackup speed and recovery efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent divides the backup process into multiple parallel streams based on file types. Each stream independently backs up files of a specific type (e.g., video files, audio files, image files), allowing simultaneous processing of different file types. This segmentation resolves the contradiction by maintaining implementation simplicity through automated stream management while dramatically improving backup speed and enabling selective recovery of specific file types.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If all file types are mixed in one backup session, then the backup process is uniform and simple, but the deduplication rate decreases

Engineering Contradiction:
Improveuniformity of backup processVSAvoiddeduplication rate
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The patent segments files into different streams based on file types, allowing deduplication to be performed independently within each stream. Files of the same type tend to have more similarities and redundancy, so processing them together maximizes deduplication efficiency. This resolves the contradiction by maintaining process uniformity through consistent stream-based handling while improving deduplication rates through type-specific processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different processing characteristics to different file type streams. Each stream can be optimized for its specific file type characteristics, allowing tailored deduplication strategies. For example, video files may use different deduplication parameters than document files. This local optimization resolves the contradiction by maintaining overall process uniformity while applying specialized quality control to each file type.

Inventive Principle:
Principle #3Local quality

3Device complexity

If all files are backed up together, then the backup structure is simple, but it is difficult to recover specific file types quickly

Engineering Contradiction:
Improvesimplicity of backup structureVSAvoidconvenience of selective file recovery
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent creates a multi-stream backup structure where each stream corresponds to a specific file type. This structure remains simple to implement through automated stream management but enables easy selective recovery - users can recover only the file types they need by selecting the corresponding stream, significantly improving recovery convenience without requiring complex manual file selection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds a file-type dimension to the backup structure, organizing files not just by location but by type characteristics. This dimensional organization maintains structural simplicity at the implementation level while enabling efficient selective recovery at the user level, as users can filter and recover files based on type rather than manually searching through all backed-up files.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
