Virtual Backup Appliance Decommissioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of an efficient mechanism for decommissioning Virtual Backup Appliances (VBAs) in backup storage systems, leading to resource wastage and data accessibility issues due to stale metadata and orphaned backup data.
Innovation Solution
A VBA decommission mechanism is introduced, allowing users to reclaim resources by deleting associated data and metadata, both locally and remotely, using a backup server that communicates with the VBA and deduplicated storage systems to remove data and metadata, ensuring data integrity and resource recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a VBA is deleted or removed, then the VBA instance is gone, but stale metadata and orphaned data remain in the backup application and storage systems
Solution Approach 1:
The patent extracts and removes stale metadata and orphaned data from the backup application and storage systems after VBA deletion. The decommissioning mechanism specifically targets and extracts residual data elements that would otherwise remain trapped in the system, ensuring complete removal of VBA-associated information.
Solution Approach 2:
The backup application performs self-service decommissioning by automatically detecting and removing its own stale metadata and orphaned data when a VBA is deleted. The system monitors its own state and initiates cleanup operations without requiring external intervention, managing its own data integrity.
2Loss of information
If manual cleanup of stale metadata and orphaned data is performed, then data accessibility is improved, but system complexity and time consumption increase
Solution Approach 1:
The decommissioning mechanism performs preliminary actions by proactively removing stale metadata and orphaned data at the moment of VBA deletion. Rather than waiting for manual cleanup operations, the system anticipates the need for data accessibility and performs the removal action immediately when the VBA is deleted, preventing accumulation of stale data.
Solution Approach 2:
The system implements feedback mechanisms where the backup application monitors VBA deletion events and automatically triggers decommissioning operations. The system receives feedback about VBA removal and responds by initiating cleanup procedures, creating a closed-loop control system that maintains data accessibility without manual intervention.
3Productivity
If automatic decommissioning is implemented, then resource reclamation is efficient, but device complexity increases
Solution Approach 1:
The decommissioning mechanism is designed as a universal solution that handles multiple types of data removal (metadata from backup application, orphaned data from storage systems, stale data from remote backups) through a single integrated process. This multi-functional approach consolidates what would otherwise require separate cleanup mechanisms into one unified system.
Solution Approach 2:
The patent introduces an intermediary decommissioning mechanism that acts as a mediator between VBA deletion and complete data removal. This intermediary layer coordinates the removal process across multiple systems (backup application, local storage, remote storage), managing the complexity of cross-system data reclamation while presenting a simple interface to users.
Data Source
AI summary
Various methods and techniques are disclosed to manage resources of virtual backup appliances in a backup and recovery network. In one embodiment, a backup server receives a request to decommission a virtual backup appliance (VBA) of a first primary storage system. The backup server is configured to manage backup operations to back up data from a plurality of primary storage systems to a backup storage system over a network, where each primary storage system has one or more VBA that carry out backup operations. In response to the request, the backup server transmits a first request to the first primary storage system over the network to delete data and metadata related to the data associated with the VBA. The back up server then determines whether the backup storage system contains data associated with the requested VBA. Upon the determination, the backup server transmits a second request to the backup storage system to delete the data associated with the requested VBA from the backup storage system. The backup server then deletes a second metadata associated with the VBA, and then unregisters the VBA from the backup and recovery network.
