Virtual Machine Image Creation for Legacy Bare Metal Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy computer systems with hardware failures or obsolescence pose challenges in data preservation and system recovery due to the need for obsolete hardware and unsupported software, making traditional recovery and migration processes cumbersome and costly.
Innovation Solution
Creating a virtual machine image from a backup image of the legacy system's hard drive, allowing the original environment to be recreated on modern hardware without the need for hardware repair or replacement, enabling data preservation and accessibility post-retirement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bare metal recovery is used to rebuild a failed system, then the system can be restored to operational status, but the process requires locating and installing obsolete hardware components and their corresponding drivers, increasing complexity and cost
Solution Approach 1:
The patent creates a virtual copy of the failed system's hard drive image and loads it into a virtual machine environment. This virtual copy preserves the original system state and data while running on modern hardware through virtualization, eliminating the need to physically locate and install obsolete hardware components and their drivers.
Solution Approach 2:
The patent introduces a virtual machine as an intermediary layer between the backup image and the modern hardware. The virtual machine abstracts the hardware interface, allowing the legacy system image to run on contemporary hardware without requiring direct hardware compatibility or driver installation for the original obsolete components.
2Ease of repair
If hardware components are replaced to repair a failed system, then the system may become operational, but the replacement components may have incompatible drivers in the backup image, requiring additional software configuration
Solution Approach 1:
The virtual machine serves as an intermediary that abstracts the hardware layer, allowing any modern hardware to be used for repair without worrying about driver compatibility. The virtual machine presents a standardized interface to the legacy system image, eliminating the need to match drivers with specific hardware components.
Solution Approach 2:
The virtual machine environment provides universal compatibility across different modern hardware platforms. The same virtual machine image can run on various modern computers without modification, making the repair process hardware-agnostic and eliminating the need for platform-specific driver configuration.
3Loss of information
If obsolete systems are maintained to preserve data and software environments, then data accessibility is maintained, but hardware maintenance costs and system complexity increase
Solution Approach 1:
Instead of maintaining the original obsolete hardware, the patent creates and maintains a virtual copy of the system image. This virtual copy preserves all data and software environments exactly as they existed, while running on modern, supported hardware that receives regular updates and security patches, eliminating the need to maintain aging physical infrastructure.
Solution Approach 2:
The patent replaces the physical mechanical hardware system with a virtualized software-based system. By substituting the obsolete physical hardware with a virtual machine running on modern infrastructure, the solution maintains data preservation capabilities while eliminating hardware maintenance costs and extending system lifecycle.

AI summary
A legacy computer system receives a hard drive or other hardware failure. Rather than attempting to rebuild the computer system or recover selected data, which may require locating discontinued hardware or even software, a virtual machine image is created from a previously prepared backup image of the hard drive. The retrieved backup image is modified to create a virtual image that is bootable on a virtual machine. Thus, the original computer environment stored on the legacy system is now virtualized removing the need to repair or replace the failed hardware.
