Backup Component Captures User Interface Views via SPIs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data recovery systems face challenges in efficiently restoring previous versions of user interface views, particularly when users want to revert changes made to files, as the undo feature is limited to chronological reversals and may not function after saving and closing documents.
Innovation Solution
A system and method that include a backup component capable of capturing and restoring user interface views, using Service Provider Interfaces (SPIs) to communicate with applications, allowing users to select and restore earlier versions of application data, including format information for generating visual representations of previous states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional undo features are used to revert changes, then the user can reverse recent edits, but the user cannot restore previous versions after saving and closing documents
Solution Approach 1:
The system performs preliminary actions by automatically capturing and storing snapshots of the user interface view at different points in time before the user needs to restore data. These snapshots are saved in advance using SPIs, allowing the user to restore to any previous state without having to perform undo operations in reverse chronological order.
Solution Approach 2:
The system creates copies of the user interface view state at different timestamps and stores them separately. Instead of modifying the original data in place, the patent captures snapshots that are stored as separate copies, allowing the user to restore to any previous version without affecting the current state until restoration is explicitly chosen.
2Reliability
If the system captures and stores multiple versions of user interface views, then the user can restore previous versions, but the system requires additional storage resources
Solution Approach 1:
The system extracts only the essential state information of the user interface view that needs to be restored, rather than storing complete copies of all application data. By using SPIs to capture specific view states and format information, the patent reduces the amount of data stored while maintaining the ability to restore previous versions.
3Ease of operation
If the system integrates backup data into the application's user interface, then the user can efficiently restore previous versions, but the system requires complex communication interfaces
Solution Approach 1:
The patent implements Service Provider Interfaces (SPIs) that provide universal communication mechanisms between the backup component and the application. These SPIs handle multiple functions including capturing view states, storing snapshots, and restoring data, thereby reducing the need for multiple specialized interfaces and simplifying the overall system architecture.
