Backup Image Recovery Using File Segmentation and External Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disaster recovery methods are slow due to the large amount of data that needs to be restored, often including unnecessary files and outdated data, which can hinder quick access to critical systems and services.
Innovation Solution
A method that scans files on storage devices, identifies essential files for recovery, excludes unnecessary files from the backup image, and stores them externally, using links within the backup image, and updates files to their latest versions post-recovery using a synchronization driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all files are included in the backup image for complete recovery, then recovery completeness is improved, but recovery speed deteriorates due to large data volume
Solution Approach 1:
The patent segments files into two categories: files needed for initial system launch and operation, and files not needed for initial launch. This segmentation allows the backup image to contain only essential files for quick recovery, while non-essential files are restored separately from external storage, thereby improving recovery speed without sacrificing completeness
Solution Approach 2:
The patent extracts files that are not needed for initial system launch from the backup image and stores them externally. This extraction reduces the backup image size and accelerates the initial recovery process, while ensuring that extracted files can be retrieved later to achieve complete recovery
2Reliability
If outdated files are included in the backup image, then recovery completeness is improved, but system performance deteriorates due to outdated data
Solution Approach 1:
The patent performs preliminary synchronization of files before creating the backup image. This preliminary action ensures that files are updated to their latest versions before being backed up, preventing outdated files from being restored and maintaining system performance while ensuring recovery completeness
3Speed
If critical files are excluded from the backup image to reduce size, then recovery speed is improved, but recovery reliability deteriorates
Solution Approach 1:
The patent applies local quality by differentiating between files needed for initial system launch and those not needed. Essential files are included in the backup image with high priority for immediate restoration, while non-essential files are restored later from external storage, ensuring both speed and reliability
Data Source
AI summary
Disclosed herein are systems and method for performing recovery using a backup image. In one exemplary aspect, a method comprises scanning a plurality of files on one or more storage devices of a computing device. The method may determine a first set of files from the plurality of files that will be used during recovery of the one or more storage devices, and tag a second set of files that will not be used during recovery. The method may copy the second set of files that have been tagged to an external storage device, and may store the first set of files in a backup image for the computing device (excluding the tagged second set of files from the backup image). The method may add, to the backup image, a respective link to each of the tagged second set of files in the external storage device.
