Virtual Machine Snapshot Mounting for Isolated Ransomware Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data management systems struggle to efficiently and reliably recover virtual machines (VMs) from ransomware attacks by facilitating effective investigation and recovery procedures in isolated environments, leading to potential data loss and increased risk of further malware spread.
Innovation Solution
A data management system (DMS) orchestrates the recovery of VMs into isolated testing environments, allowing live mounts of snapshot data for parallel investigation and recovery, enabling efficient testing and identification of reliable VMs for restoration to the production environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If VMs are recovered to production environment directly, then recovery speed is improved, but risk of malware spread and data loss increases
Solution Approach 1:
The system segments the recovery process into two distinct phases: first recovering VMs to an isolated testing environment, then selectively restoring verified VMs to the production environment. This segmentation allows security validation to occur separately from the recovery operation, eliminating the trade-off between speed and reliability.
Solution Approach 2:
The isolated testing environment serves as an intermediary between the backup storage and the production environment. VMs are first restored to this intermediate environment where they can be validated for malware and data integrity before being promoted to production, thus ensuring reliability without sacrificing recovery speed.
2Reliability
If VMs are tested in isolated environment before recovery, then recovery reliability is improved, but recovery time increases
Solution Approach 1:
The system performs preliminary actions by restoring VMs to the isolated testing environment and conducting security validations before final recovery to production. This preliminary validation prevents future failures and malware spread, ensuring that the time invested is worthwhile by avoiding costly re-recovery operations.
Solution Approach 2:
The testing and validation processes occur in parallel where possible, and the isolated environment remains actively managed rather than creating sequential bottlenecks. The system continuously monitors and validates VMs in the testing environment, maintaining useful action throughout the process rather than creating idle waiting periods.
3Productivity
If multiple VMs are tested in parallel, then productivity is improved, but system complexity increases
Solution Approach 1:
The system segments the parallel testing workload across multiple isolated testing environments, with each environment capable of hosting and validating VMs independently. This segmentation allows parallel processing without requiring complex inter-VM communication or coordination, managing complexity through spatial separation.
Solution Approach 2:
The isolated testing environments are designed as universal platforms that can host multiple VMs and perform various validation functions simultaneously. Each testing environment serves multiple purposes: malware detection, data integrity verification, and functional testing, reducing the need for specialized infrastructure for each testing type.
Data Source
AI summary
A data management system (DMS) may facilitate an investigation procedure for a set of one or more virtual machines (VMs) hosted in a first environment. The DMS may receive an indication of a selection of one or more sets of VMs and corresponding snapshots for the investigation procedure. The corresponding snapshots may be stored in a second environment, and each snapshot may be associated with a version of a respective set of VMs. The DMS may mount the one or more sets of VMs to one or more testing environments different than the first and second environments. The mounting may use the snapshots stored in the second environment to provide the testing environments with query access to respective versions of the sets of VMs hosted in the first environment. The DMS may perform query operations between the first environment and the testing environments as part of the investigation procedure.
