Immutable Snapshot Recovery for Low-RTO Backup Vaults
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data recovery systems face challenges in achieving low Recovery Time Objective (RTO) and Recovery Point Objective (RPO) with limited granularity and optionality, and often require data production and backup environments to be coupled, limiting flexibility and cloud-based solutions, while not allowing for data cleaning and analysis.
Innovation Solution
A data recovery system that decouples the vault architecture from the production environment, enabling data cleaning, scrubbing, and analysis in a virtual recovery environment, with storage snapshots for immutability, and supports cloud-based backup, reducing RTO and enhancing RPO granularity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data production and backup environments are coupled, then data protection is ensured, but system flexibility and cloud-based solution capability are limited
Solution Approach 1:
The patent divides the traditional coupled data production and backup environment into separate virtualized components. The data production environment runs on production hardware while the backup environment operates independently on separate hardware infrastructure, allowing each to be optimized and managed independently while maintaining data protection through virtualized backup agents and storage connections.
Solution Approach 2:
The patent introduces a virtualized backup agent as an intermediary component that bridges the data production environment and the separated backup environment. This agent enables data protection functionality while allowing the backup infrastructure to be independently located, managed, and potentially cloud-based, thus maintaining reliability while improving flexibility.
2Reliability
If traditional data recovery systems are used, then data backup is achieved, but Recovery Time Objective (RTO) is increased and RPO granularity is limited
Solution Approach 1:
The patent implements continuous data replication and pre-positioning of backup data in the separated backup environment before failures occur. Virtualized backup agents continuously capture and transfer data changes, so that when recovery is needed, data is already prepared and available, significantly reducing RTO compared to traditional on-demand backup approaches.
Solution Approach 2:
The patent creates virtual copies of production data through virtualized backup agents that replicate data to the separated backup environment. These copies can be rapidly restored to production systems, reducing recovery time while maintaining data integrity and backup reliability.
3Reliability
If data cleaning and analysis are not permitted in backup environment, then data protection is maintained, but data utility and verification capability are reduced
Solution Approach 1:
The patent extracts data cleaning and analysis functions from the protected backup environment and performs them in the separated backup environment or external systems. This allows data to be processed, validated, and cleaned without compromising the integrity of the protected backup data, thereby improving data utility while maintaining protection.
Solution Approach 2:
The patent uses the virtualized backup agent and separated backup environment as intermediaries that enable data cleaning and analysis operations. These intermediaries allow processing activities to occur on backup data without affecting the integrity of the primary protected data, thus improving data utility while preserving data protection.
