Raw Disk Backup Prioritization for Fast Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data protection systems face challenges in efficiently managing backups and restorations, often requiring significant computational resources and time, which can impact system performance and lead to data loss due to device failures without adequate backup solutions.
Innovation Solution
A system that prioritizes backup services by using a priority list to determine whether a client is high or low priority, generating and storing raw disk backups in raw format for high-priority clients, allowing for faster restoration by directly accessing disk volumes without additional processing, while non-raw disk backups are used for lower priority clients, optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If raw disk backups are generated and stored for all clients, then restoration time is reduced, but storage costs and computational resources increase
Solution Approach 1:
The patent applies local quality by providing different backup types to different clients based on their restoration priority. High-priority clients receive raw disk backups that enable fast restoration, while lower-priority clients receive standard backups. This differentiated approach ensures that the resource-intensive raw disk backup format is only used where it provides the most value, optimizing the balance between restoration speed and storage resource consumption.
2Speed
If computational resources are allocated for fast restoration, then restoration speed improves, but system performance during normal operation deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-generating and storing raw disk backup images during scheduled backup windows when system performance impact is acceptable. These pre-prepared raw backups are then immediately available for fast restoration without requiring computational resources during the restoration process itself. This approach separates the computationally intensive backup creation phase from the restoration phase, ensuring that restoration speed is not compromised while minimizing impact on normal system operations.
3Reliability
If data is protected through comprehensive backup, then data loss prevention improves, but backup management complexity increases
Solution Approach 1:
The patent applies segmentation by dividing clients into different priority groups (high-priority and lower-priority clients) and applying different backup strategies to each segment. High-priority clients receive raw disk backups with fast restoration capability, while lower-priority clients receive standard backups. This segmented approach simplifies backup management by providing clear, differentiated policies for different client groups while ensuring comprehensive data protection across all clients through appropriate backup selection.

AI summary
A backup manager for providing backup services to clients includes storage for storing a priority list. The backup manager also includes a processor programmed to obtain a request to generate a backup for a client of the clients; make a determination that the client is a high restoration priority client using the priority list; in response to the determination: obtain a raw disk backup for the client; and store the raw disk backup in backup storage in raw disk format.
