Storage Manager Database Restoration via Non-Production Media Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information management systems face challenges in restoring storage manager databases without pre-created secondary copies, leading to loss of access to non-production data in case of database disasters, and require additional resources and complexity for disaster recovery.
Innovation Solution
The implementation of a restore agent that scans non-production storage media, such as magnetic tapes, to retrieve headers and metadata, allowing the reconstruction of a storage manager database without prior secondary copies, and enables consolidation of multiple information management cells into a single cell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a second managing computing device is maintained to mirror the database for disaster recovery, then data reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent creates a secondary copy of the storage manager database on non-production storage media. This copy serves as a backup that can be restored if the primary database is lost, providing disaster recovery capability without requiring a complete second managing computing device. The copy includes all necessary mapping information to restore non-production data to client computing devices.
Solution Approach 2:
The patent extracts the critical database backup function from the complex managing computing device infrastructure and places it on separate non-production storage media. This separation allows the backup functionality to be maintained independently, reducing the complexity of the primary system while ensuring recovery capability.
2Reliability
If secondary copies of the managing computing device database are created and maintained, then data reliability is improved, but resource consumption increases
Solution Approach 1:
The patent creates a secondary copy of the storage manager database on non-production storage media, which consumes resources but provides essential recovery capability. The copy is maintained as a lightweight alternative to full system redundancy.
3Loss of energy
If the storage manager database is lost without pre-created secondary copies, then resource consumption is reduced, but loss of information occurs
Solution Approach 1:
The patent performs preliminary action by creating a secondary copy of the storage manager database before any disaster occurs. This advance preparation ensures that recovery information is available immediately when needed, preventing loss of access to non-production data.
4Reliability
If a restore agent scans all non-production storage media to reconstruct the database, then data reliability is improved, but loss of time occurs during restoration
Solution Approach 1:
The patent performs preliminary action by pre-creating and maintaining a secondary copy of the storage manager database on non-production storage media. This eliminates the need to scan all media during restoration, as the pre-prepared copy can be immediately loaded and used to restore the storage manager functionality.
Data Source
AI summary
Systems and methods for restoring a database in an information management system that does not include a secondary copy of the database, are disclosed. The systems and methods may include using metadata stored in non-production storage devices to restore the database. In some implementations the methods are used to consolidate multiple information management systems. In other implementations, the systems and methods are used for reviewing content of archived storage media. Other implementations are disclosed.
