Regenerated Container File Differential Storage

Solution Overview

Problem

Existing container file management systems lack efficiency in transmitting and storing updated container files, as they often require sending entire files instead of just the differences, leading to bandwidth and storage inefficiencies.

Innovation Solution

A container file management system that detects regenerated container files and sends only the differences to the data storage, using manifests to identify new or modified files and store them in segment-sized portions, optimizing transmission and storage by comparing metadata and file hashes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If entire container files are transmitted and stored, then data integrity is ensured, but bandwidth usage and storage space are inefficiently consumed

Engineering Contradiction:

Improvedata integrityVSAvoidbandwidth usage

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent extracts only the differential portions (new or modified files) from the regenerated container file and transmits only these extracted differences to the remote system. This eliminates the need to transmit entire container files while maintaining data integrity through selective transmission of changed content.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the container file transmission process by identifying and separating modified files from unchanged files using manifest comparison. Only the segmented differential portions are transmitted, while the rest of the container file structure remains on the local system.

Inventive Principle:

Principle #1Segmentation

2Reliability

If entire container files are transmitted and stored, then data completeness is ensured, but storage space is inefficiently consumed

Engineering Contradiction:

Improvedata completenessVSAvoidstorage space

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the differential portions (new or modified files) from the regenerated container file and stores only these extracted differences at the remote system. This eliminates the need to store entire container files while maintaining data completeness through selective storage of changed content.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the container file storage by identifying and separating modified files from unchanged files using manifest comparison. Only the segmented differential portions are stored remotely, while the rest of the container file structure remains on the local system.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If entire container files are transmitted, then transmission simplicity is maintained, but transmission time increases

Engineering Contradiction:

Improvetransmission simplicityVSAvoidtransmission time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent extracts only the differential portions (new or modified files) from the regenerated container file and transmits only these extracted differences to the remote system. This eliminates the need to transmit entire container files while maintaining data integrity through selective transmission of changed content.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A regenerated container file is detected, and a file in the regenerated container file is determined that is different from any file in an existing container file related to the regenerated container file. To store the regenerated container file, the different file is sent to the data storage for storing.
