Selective Storage Backup for Disaster Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disaster recovery methods are inflexible and time-consuming, requiring whole-system recovery and dedicated resources, leading to inefficiencies and resource wastage.
Innovation Solution
A system and method that allow users to select specific source storage resources for backup, establishing corresponding backup storage resources and providing access to them in case of inaccessibility, while avoiding unnecessary resource allocation and maintaining transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If whole-system recovery is performed for all stored resources, then reliability is improved, but recovery time increases and resource utilization deteriorates
Solution Approach 1:
The patent segments the storage system into multiple storage resources that can be independently selected and backed up. Instead of treating the entire storage system as a single unit, the system allows users to select specific storage resources for backup, enabling partial recovery operations that reduce recovery time while maintaining reliability for critical resources.
Solution Approach 2:
The patent implements partial recovery by allowing users to select only the necessary storage resources for backup rather than performing complete system recovery. This partial action approach reduces the time and resources required for disaster recovery while maintaining sufficient protection for the selected critical resources.
2Reliability
If dedicated storage areas are reserved for backup, then reliability is improved, but resource utilization deteriorates
Solution Approach 1:
The patent enables backup storage resources to serve multiple functions. The same storage resources can be used for both primary data storage and backup purposes, eliminating the need for dedicated separate storage areas. This multi-functionality approach maintains reliability through backup capability while improving overall resource utilization efficiency.
Solution Approach 2:
The patent implements a mechanism where backup storage resources can be discarded or released when no longer needed, and the space can be recovered for other uses. This dynamic resource management allows the system to maintain backup capability when necessary while optimizing resource utilization by making backup storage available for other purposes when not in use.
3Reliability
If coarse granularity recovery is performed, then reliability is improved, but flexibility deteriorates and user experience worsens
Solution Approach 1:
The patent segments the recovery process into fine-grained operations at the storage resource level. Instead of treating the entire storage system as a single recoverable unit, the system allows users to select and recover specific storage resources independently, providing fine-grained control and flexibility in the recovery process while maintaining reliability.
Solution Approach 2:
The patent implements dynamic recovery capabilities where the recovery process can be adjusted based on user needs. The system allows users to dynamically select which storage resources to recover, when to recover them, and how to manage the recovery process, providing adaptability and flexibility rather than rigid coarse-grained recovery operations.
