Selective Data Replication for DRaaS Cost Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Disaster-Recovery-as-a-Service (DRaaS) systems face challenges in optimizing data transfer and storage costs, particularly in terms of network bandwidth and storage footprint, especially when serving numerous clients with large volumes of data, leading to resource bottlenecks at the target site.
Innovation Solution
The implementation of an optimized DRaaS system that uses selective data transfer by analyzing client data and applying an essentialness assessment to determine which data components to replicate, along with policy configuration to minimize costs, employing techniques like deduplication, compression, and optimized network protocols, and providing value-added services such as virus scanning and anomaly detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all client data is replicated to the target site for disaster recovery, then data protection reliability is improved, but network bandwidth consumption and storage footprint increase significantly
Solution Approach 1:
The patent extracts and replicates only the essential and changed data components to the target site, rather than replicating all client data. The essentialness assessment module identifies which data components are critical for disaster recovery, and only those selected components are transferred, thereby reducing network bandwidth consumption while maintaining data protection reliability.
Solution Approach 2:
The patent applies different replication strategies to different data components based on their essentialness and change status. Critical data components that have changed are replicated with high priority, while non-essential or unchanged components are not replicated, creating a localized quality approach where replication intensity varies by data component importance.
2Reliability
If all client data is stored at the target site, then data protection reliability is improved, but storage footprint and cost increase
Solution Approach 1:
The patent extracts only the essential data components needed for disaster recovery and stores them at the target site. The essentialness assessment module determines which data components are critical, and only those are selected for storage, thereby reducing storage footprint while maintaining data protection reliability.
Solution Approach 2:
The patent applies partial action by storing only a portion of the client data - specifically, the essential and changed data components - rather than storing all data. This partial replication approach reduces storage footprint at the target site while still providing adequate disaster recovery protection.
3Reliability
If data replication is performed continuously to ensure data protection, then reliability is improved, but network bandwidth consumption increases
Solution Approach 1:
The patent implements periodic action by monitoring data components for changes and replicating only when changes occur, rather than performing continuous replication. The change detection mechanism triggers replication events periodically based on actual data changes, reducing network bandwidth consumption while maintaining data protection reliability through event-driven updates.
Solution Approach 2:
The patent maintains continuity of useful action by continuously monitoring data components for changes and immediately replicating essential changed components to the target site. This continuous monitoring and selective replication ensures data protection reliability is maintained without the overhead of continuous full-data replication, optimizing network bandwidth usage.

AI summary
Methods, computer program products, and systems are presented. The methods include, for instance: analyzing a dataset associated with a service provided by the data protection service provider in order to determine a policy for when and how to replicate the respective components of the dataset corresponding to the service from a source site to a target site, such that the target site may perform the service with a minimum cost.
