VM Backup Image Splitting for Anomaly-Isolated Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual machine backup systems lack the ability to capture detailed information about applications and user data, making it difficult to ensure backup integrity and perform customized operations, which can lead to corrupted recovery operations.
Innovation Solution
A method that involves monitoring virtual machine events, generating backup-ready metadata, and logically splitting backup images into portions using this metadata to identify and isolate anomalies, allowing for enhanced backup and recovery operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the entire backup image is stored without splitting, then storage efficiency is improved, but the ability to perform customized recovery operations and ensure backup integrity deteriorates
Solution Approach 1:
The backup image is divided into multiple logical portions based on application and user data boundaries identified through monitoring VM events. This segmentation enables selective recovery of specific portions while maintaining storage efficiency, resolving the contradiction between whole-image storage and customized recovery capability
2Reliability
If detailed application and user data information is captured, then backup integrity and customized operations are improved, but device complexity and processing overhead increase
Solution Approach 1:
The system performs preliminary monitoring of VM events and captures application/user data information during the backup creation process. This preliminary action organizes metadata beforehand, enabling efficient anomaly detection and customized recovery operations without excessive processing overhead during actual backup or recovery operations
3Reliability
If the backup image is split into multiple logical portions, then the ability to isolate and remove anomalies is improved, but storage management complexity increases
Solution Approach 1:
A metadata database serves as an intermediary between the backup image portions and the storage management system. This metadata database tracks the logical portions, their boundaries, and associated applications, simplifying storage management while enabling effective anomaly isolation and removal through the structured organization provided by the metadata

AI summary
Techniques described herein relate to a method for enhancing backup and recovery of a VM, including receiving, in connection with a backup operation, a backup-ready metadata database and a backup image of the VM at a backup storage. The method also includes logically splitting, using the backup-ready metadata database, the backup image into multiple logical portions. The method further includes performing a cyber recovery operation on one of the logical portions. In addition, the method includes performing an action from an action set in response to the cyber recovery operation.
