Multi-Cloud Backup Addressing Using Blockchain Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of managing and securing data across multiple cloud platforms, known as multi-cloud platforms, arises due to the risk of a single-point bottleneck when relying on a single cloud platform, which can lead to data loss and security threats.
Innovation Solution
Implementing a data management method that utilizes a blockchain network for decentralized, secure data management by dividing data into blocks and encoding metadata into backup identifiers, ensuring distributed storage and unified addressing across multi-cloud platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is stored on a single cloud platform, then storage simplicity is improved, but data security and reliability deteriorate due to single-point bottleneck
Solution Approach 1:
The patent segments data into multiple data blocks and distributes them across multiple cloud platforms. Each cloud node stores only a portion of the data, eliminating the single-point bottleneck while maintaining storage simplicity through automated distribution management.
Solution Approach 2:
The patent introduces a blockchain network as an intermediary to manage and coordinate data storage across multiple cloud platforms. The blockchain stores metadata and backup identifiers, enabling unified management without requiring direct complex interactions between cloud platforms.
2Reliability
If data is distributed across multiple cloud platforms, then data security is improved, but management complexity worsens
Solution Approach 1:
The blockchain network serves as an intermediary that simplifies management of distributed data. It stores metadata including backup identifiers that map data blocks to their storage locations across cloud platforms, providing a unified interface for data management operations.
Solution Approach 2:
The system performs preliminary actions by pre-storing metadata and backup identifiers in the blockchain before actual data retrieval operations. This advance preparation enables efficient data location and recovery without complex real-time coordination between cloud platforms.
3Reliability
If data is divided and stored in distributed manner, then security is improved, but data query efficiency worsens
Solution Approach 1:
The blockchain acts as an intermediary that stores indexing information (backup identifiers and metadata) that enables efficient querying of distributed data. The blockchain's distributed ledger structure allows parallel verification and quick location of data blocks across multiple cloud platforms.
Solution Approach 2:
The system pre-computes and stores backup identifiers and metadata in the blockchain before data retrieval operations. This preliminary indexing enables efficient data location without requiring complex real-time searches across distributed cloud storage systems.

AI summary
A data management method includes a client that receives a backup plan configured by a user for to-be-backed-up data; the client divides the to-be-backed-up data into c data blocks based on a quantity of cloud nodes used for backup and a quantity of backup copies, and stores the c data blocks in n cloud nodes on multi-cloud platforms in a distributed manner, where for at least one data block in the c data blocks, the multi-cloud platforms store b backup copies of the at least one data block; and the client provides, for a blockchain network, metadata of the data stored on the multi-cloud platforms, such that the blockchain network encodes the metadata into a backup identifier, and stores the backup identifier, where the backup identifier is used to address the data stored on the multi-cloud platforms.
