Backup Asset Wrapper Services for Phased Legacy System Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transitioning from legacy data protection systems to next-generation systems is complex and disruptive, requiring careful planning and often spanning months to years, with challenges including support gaps, regulatory compliance, and the need for phased coexistence due to varying asset types and customer base limitations.
Innovation Solution
A phased approach involving an abstraction layer and asset-specific wrapper services enables seamless transition of backup assets from legacy to new systems, allowing coexistence and incremental integration without requiring changes to the new system, using an iterative process to assess and transition each asset individually.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a one-click or rip-and-replace approach is used to transition from legacy backup systems to next-generation systems, then the transition speed and simplicity are improved, but the risk of disruption and failure increases due to support gaps and asset compatibility issues
Solution Approach 1:
The patent segments the backup asset base into compatibility groups based on asset type, platform, and support availability. This allows the transition to proceed in manageable chunks rather than attempting a monolithic replacement, reducing risk while maintaining progress.
Solution Approach 2:
The patent performs preliminary compatibility assessment and wrapper service preparation before actual transition execution. By pre-identifying compatible assets and preparing wrapper services in advance, the system enables faster transitions without compromising reliability.
2Reliability
If legacy and next-generation backup systems coexist side-by-side during transition, then the risk and disruption are reduced, but the system complexity and management overhead increase
Solution Approach 1:
The patent introduces an abstraction layer with wrapper services as intermediaries between legacy backup assets and the next-generation system. This mediator enables unified management of both legacy and modern systems through a common interface, reducing the perceived complexity while maintaining safe coexistence.
Solution Approach 2:
The abstraction layer provides universal interfaces that work with both legacy and next-generation systems. This multi-functionality allows a single management plane to handle diverse backup assets regardless of their origin, simplifying operations during the transition period.
3Adaptability or versatility
If all backup asset types are supported immediately in the next-generation system, then the completeness of support is improved, but the implementation complexity and time required increase due to incremental delivery requirements
Solution Approach 1:
The patent extracts the compatibility assessment logic and wrapper service generation from the main transition process. This separation allows the system to handle supported assets through standard pathways while routing unsupported assets to wrapper services, maintaining versatility without proportionally increasing implementation complexity.
4Measurement precision
If a comprehensive compatibility assessment is performed for all backup assets before transition, then the accuracy of transition planning is improved, but the time and resources required for assessment increase
Solution Approach 1:
The patent performs compatibility assessment selectively based on asset criticality and change risk. High-priority assets receive comprehensive assessment while lower-priority assets undergo streamlined evaluation. This partial action approach maintains sufficient accuracy for decision-making while reducing overall assessment time and resources.
Data Source
AI summary
One example method includes [searching a legacy data backup system and identifying, in the legacy data backup system, a legacy backup asset, identifying a type of the legacy backup asset, creating a wrapper service instance that corresponds to the type of the legacy backup asset, detaching the legacy backup asset from the legacy data backup system, receiving, by the legacy backup asset, backup calls and restore calls from a new data backup system that is different from the legacy data backup system, and servicing, by the legacy backup asset the backup calls and restore calls based on a state of the legacy backup asset.
