Automated Backup Plan Reconfiguration During Storage Failover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing enterprise backup software requires manual reconfiguration of backup plans during failover events, leading to delays that can violate protection service level agreements (SLAs) in information processing systems.
Innovation Solution
Automated techniques for managing backup plans that automatically subscribe or unsubscribe application instances from a data backup plan based on the status of host devices and storage systems, enabling seamless failover without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual reconfiguration of backup plans is performed during failover events, then backup plan accuracy is maintained, but reconfiguration time increases causing SLA violations
Solution Approach 1:
The system performs preliminary actions by detecting failover events and automatically reconfiguring backup plans before manual intervention is needed. The backup administrator system proactively identifies when failover occurs and initiates reconfiguration of backup plans to reference the correct disaster recovery storage system, eliminating the time delay associated with manual reconfiguration while maintaining accuracy.
2Loss of time
If automated reconfiguration is implemented, then reconfiguration time is reduced, but system complexity increases
Solution Approach 1:
The system uses feedback mechanisms where the backup administrator system continuously monitors the status of storage systems and replication links. When a failover event is detected, the system automatically responds by reconfiguring backup plans. This feedback loop enables automated reconfiguration without requiring complex manual procedures, as the system self-adjusts based on real-time status information from the storage infrastructure.
3Manufacturing precision
If manual intervention is required for backup plan reconfiguration, then reconfiguration accuracy is maintained, but operational efficiency decreases
Solution Approach 1:
The backup administrator system performs self-service by automatically detecting failover events and reconfiguring backup plans without requiring manual intervention. The system monitors replication status, identifies when disaster recovery storage systems become active, and autonomously updates backup plan references to point to the correct active storage system, thereby maintaining accuracy while dramatically improving operational efficiency.
Data Source
AI summary
Techniques for managing backup plans in information processing systems are disclosed. For example, a method comprises managing a data backup plan for an information processing system comprising a set of host devices that execute application instances for which data is stored on a first storage system and mirrored on a second storage system. After a given condition is detected, managing the data backup plan comprises reconfiguring the data backup plan by: (i) automatically subscribing, to the data backup plan, one or more of the application instances that execute on one or more active ones of the set of host devices configured to store data on the second storage system; and (ii) automatically unsubscribing, from the data backup plan, one or more of the application instances that previously executed on one or more non-active ones of the set of host devices configured to store data on the first storage system.
