Cross-Grid Replication for Ransomware-Resilient Distributed Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional distributed storage systems are vulnerable to localized failures, ransomware attacks, and unauthorized access due to limited geographical dispersal of replicated data, which compromises data integrity and availability.
Innovation Solution
Implementing cross-grid replication, where data is strategically dispersed across multiple interconnected storage grids, enhancing data resilience and disaster recovery capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is replicated within a single storage grid, then data redundancy and availability are improved, but vulnerability to localized failures and ransomware attacks increases
Solution Approach 1:
The patent segments the storage infrastructure into multiple independent storage grids, each operating as a separate replication domain. By dividing the replicated data across these segmented grids rather than concentrating all replicas within a single grid, the system limits the propagation of ransomware attacks to only affected segments while preserving data availability from other grids.
Solution Approach 2:
The patent introduces a new dimensional aspect to data replication by implementing cross-grid replication alongside traditional intra-grid replication. This creates a multi-dimensional replication architecture where data exists across both single-grid and multi-grid boundaries, adding geographical and administrative separation as new dimensions that reduce vulnerability to localized threats.
2Reliability
If data is replicated across multiple storage grids, then resilience against localized failures is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal replication framework that handles both intra-grid and cross-grid replication through a common architecture and control plane. This multi-functional system manages different replication scenarios (single-grid and multi-grid) using unified protocols and mechanisms, reducing the operational complexity that would otherwise arise from maintaining separate replication systems.
Solution Approach 2:
The patent introduces intermediary components such as replication controllers and coordination services that mediate between storage grids during cross-grid replication operations. These intermediaries simplify the complexity by centralizing the management of replication state, handling synchronization protocols, and coordinating failover scenarios across multiple grids, thereby reducing the burden on individual storage nodes.
3Reliability
If cross-grid replication is implemented, then disaster recovery capabilities are improved, but data access time may increase
Solution Approach 1:
The patent implements preliminary replication actions where data is proactively copied across storage grids before failures occur. By maintaining pre-synchronized replicas in multiple grids during normal operations, the system eliminates the need for time-consuming data recovery operations after disasters, as ready-to-use replicas are already available in distant grids.
Solution Approach 2:
The patent applies local quality optimization by intelligently directing data access requests to the nearest or most appropriate storage grid based on location, load conditions, and replication status. This ensures that routine data operations benefit from low-latency local access while disaster recovery operations automatically leverage remote grid replicas, thereby minimizing the impact on normal data access performance.

AI summary
Various embodiments of the present technology generally relate to systems and methods for providing cross-grid replication within distributed storage systems. In an example, a method includes identifying an object for ingest into a first storage grid containing a first distributed storage system and replicating the object to one or more nodes within the first storage grid. The method may also include determining a cross-grid replication status of the object to a second storage grid containing a second distributed storage system and performing a cross-grid replication of the object to the second storage grid based on the cross-grid replication status of the object.
