Gateway Backup System Using Signature Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backup systems for gateways are inefficient in managing and restoring data, particularly in networked environments, leading to resource-intensive bandwidth usage and potential data corruption.
Innovation Solution
A backup method and system that categorizes data elements and creates signatures with sub-signatures to efficiently identify and update data on a gateway, allowing for precise copying of changed data elements to a database, thereby maintaining data integrity and reducing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all data elements are backed up to the database, then data integrity is maintained, but bandwidth consumption increases
Solution Approach 1:
The data is segmented into multiple categories (e.g., device information, scene information, schedule information). Instead of backing up all data uniformly, the system segments the backup process by category and uses signatures to identify which specific categories contain changed data, thereby backing up only those segments that need updating.
Solution Approach 2:
The system extracts only the changed data elements from the complete dataset by comparing signatures. The signature mechanism allows the system to take out (extract) only the specific data categories that have changed since the last backup, rather than extracting or transmitting all data elements.
2Reliability
If data is frequently backed up, then data currency is improved, but system resources are consumed
Solution Approach 1:
The system performs preliminary action by creating and storing signatures of all data categories before the actual backup process. These signatures serve as pre-computed indicators that enable rapid identification of changed data, eliminating the need for full data comparison during each backup operation.
Solution Approach 2:
Instead of copying and transmitting all data elements during each backup, the system copies only the signatures (compact representations) for comparison. The actual data copying is limited only to those specific categories where signature mismatches indicate changes have occurred.
3Measurement precision
If signature comparison is performed for all categories, then change detection accuracy is improved, but processing time increases
Solution Approach 1:
The signature comparison process is segmented by data category. Each category has its own signature that can be independently compared. This segmentation allows the system to identify exactly which categories have changed without performing unnecessary comparisons on unchanged categories, thereby reducing overall processing time while maintaining detection accuracy.

AI summary
In embodiments, a system and method backs up and restores data stored on a gateway using a signature having sub-signatures that represent specific categories of data elements of the data, the categories regarding the operation of one or more actuating devices and possibly other items, the system and method changing the operation of the one or more actuating devices and possibly the other items based on restored or updated data elements of the data stored on the gateway.
