Auto Backup System for External Storage During Power-Off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data backup methods require a computer system to be booted up and running an operating system to transfer data from external storage devices, making the process inconvenient and limiting the functionality of connected devices.
Innovation Solution
A data auto backup system and method that initializes a computer system's bus interface and storage module while in a power-off state, using a detection unit to identify connected external storage devices and execute a backup program to upload data without booting the operating system, employing components like a bus interface, storage module, input/output interface, and power module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the computer system is booted up and running an operating system to backup data, then data backup can be performed, but the user must wait for the computer to boot up and run the operating system, increasing loss of time
Solution Approach 1:
The patent applies preliminary action by enabling the backup function to be executed before the operating system is fully loaded. The system detects external storage devices and performs data backup during the boot process, utilizing the initialization phase of the operating system to complete backup operations without requiring user waiting time.
Solution Approach 2:
The patent segments the backup function from the main operating system operations. By implementing a dedicated backup module that operates independently during system initialization, the backup process is separated from the full OS boot sequence, allowing backup to occur in parallel with essential system loading.
2Loss of time
If the computer system runs the operating system to backup data, then data can be copied to a directory of the computer, but the user is forced to wait for the computer to boot up and run the operating system regardless of whether the user wants to access the general functionality that the computer provides, increasing loss of time
Solution Approach 1:
The system performs data backup as a preliminary action during the boot process, before the user needs to access general computer functionality. This allows the backup operation to complete in the background while the system continues to initialize, so users can start using the computer immediately after boot without waiting for manual backup operations.
3Use of energy by moving object
If the computer system is in power off state, then power consumption is reduced, but data backup cannot be performed
Solution Approach 1:
The system utilizes the preliminary action principle by performing backup operations during the brief window when power is applied during boot-up, before the full system enters its powered-on state. This allows automatic backup to occur with minimal additional power consumption, leveraging the necessary power already supplied during system initialization.
4Ease of operation
If the computer system boots up to backup data, then data backup is possible, but the process is inconvenient and limits the functionality of connected devices
Solution Approach 1:
The patent segments the backup function into an independent module that operates during system initialization. This segmentation allows the backup capability to function independently without requiring the full operating system environment, thereby maintaining device functionality while enabling convenient automatic backup operations.
Solution Approach 2:
By performing backup as a preliminary action during boot-up, the system enables automatic backup without requiring the computer to be fully operational. This allows connected devices to maintain their full functionality while the backup process completes in the background during system initialization.
