Tiered Backup Metadata and Payload Storage for Faster Restore
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud storage solutions face challenges in balancing cost-effectiveness and accessibility, with long-term storage tiers causing delays due to high latency, while immediate access tiers incur high costs, complicating data management for organizations.
Innovation Solution
An information management system that separates backup payload data from metadata, storing metadata in a high-accessibility, high-cost tier and payload data in a lower-accessibility, lower-cost tier, optimizing storage characteristics based on organizational needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If backup data is stored in long-term cloud storage tier, then storage cost is reduced, but data access latency increases
Solution Approach 1:
The patent segments backup data into two distinct components: metadata (stored in high-accessibility tier) and payload data (stored in low-accessibility tier). This segmentation allows the system to optimize for both cost and accessibility by placing different data types in appropriate storage tiers based on their access patterns.
Solution Approach 2:
The patent applies local quality by assigning different storage characteristics to different parts of the backup data. Metadata, which requires frequent access for browsing and management, is stored in high-accessibility tier, while payload data, which is accessed less frequently, is stored in low-accessibility tier for cost optimization.
2Speed
If backup data is stored in immediate access cloud storage tier, then data accessibility is improved, but storage cost increases
Solution Approach 1:
The patent segments backup data into metadata and payload data, storing each in the most appropriate storage tier. This segmentation enables the system to achieve fast access for metadata operations while avoiding the high cost of storing entire backup sets in immediate access tier.
Solution Approach 2:
The patent applies local quality by storing only the metadata portion of backup data in the high-accessibility tier, giving that specific part high speed characteristics, while the payload data resides in low-accessibility tier with cost-effective characteristics.
3Ease of operation
If all backup data is stored in a single cloud storage tier, then management is simplified, but access efficiency and cost optimization are compromised
Solution Approach 1:
The patent segments backup data into metadata and payload data stored in different tiers, which initially appears to increase complexity. However, the system provides a unified interface that abstracts this complexity, maintaining ease of operation while enabling optimized access efficiency and cost management through intelligent data placement.

AI summary
Presented herein are systems and methods for backing up and restoring related backup data stored in different cloud storage tiers in a cloud storage environment. Backup data generated during a backup job is stored to different cloud storage tiers based on the type of data and a storage policy comprising designations of a first cloud storage tier and a second cloud storage tier. Backup metadata and index data is stored in the designated first cloud storage tier and backup payload data is stored in the designated second cloud storage tier. Designations of the storage tiers are based on the attributes associated with each tier of cloud storage. During restore, the backup payload data is recalled from the second storage tier into the first storage tier where it is used to restore to the destination client or customer.
