How to use trusted computing technology to build a trusted data backup system?

With the continuous growth and complexity of data scale, data backup system has become an important part of enterprise data management. Traditional data backup methods are usually based on tapes or disks and stored on a centralized backup server. However, many problems faced by this backup system, such as security, reliability, scalability, etc., are bottlenecks of traditional data backup systems. How to design and implement a trusted data backup system has become an important challenge in current backup system design.

In order to solve these problems, Trusted Computing (TC) technology was proposed and widely used in the design of data backup systems. Trusted computing technology can ensure the security and reliability of data in untrusted and threatening environments.

1. Overview of Trusted Computing Technology
Trusted computing technology refers to the use of hardware, software, protocols and other measures to ensure that the relevant resources of the computer system (including data and services, etc.) operate normally and that the resources are secure. A technology that enables trusted verification of usage and resource content. Its essence is a hardware-based secure computing environment that formulates hardware, software, and protocol specifications to provide reliable computing environment guarantees in open networks and untrusted environments.

2. Design of trusted data backup system
To design a trusted data backup system, it is necessary to use hardware and security protocols of trusted computing technology, combined with distributed storage technology, to establish reliable distributed backup system.

1. Use of trusted computing hardware
Trusted computing hardware includes Trusted Execution Environment (TEE) and Trusted Platform Module (TPM). Among them, TEE adopts a hybrid method of hardware and software. Implement a secure kernel and provide a trusted execution environment. TPM ensures the security of computing resources by embedding independent trusted platform module chips in computer hardware to store and protect sensitive information, encrypting and protecting the system startup process and remote verification and other operations.

2. Use of security protocols
In a trusted data backup system, protection measures based on security protocols need to be used to ensure the security of the transmission process. Mainly including data encryption and authentication. Data encryption is the encrypted transmission of backup data to ensure that the data is not stolen or tampered with during transmission. Identity verification ensures the security of the transmission process by verifying the validity of the identities of both parties during the transmission process.

3. Use of distributed storage technology
Distributed storage technology can ensure redundant backup of data to improve data reliability. The backup system needs to back up data to multiple nodes and distribute the nodes in different locations to avoid data loss caused by problems with a single node. At the same time, real-time dynamic backup can be achieved using distributed clustering. In this way, when a node fails, the system can automatically switch to other nodes to ensure data continuity.

3. Application of Trusted Data Backup System
Trusted data backup system is widely used in finance, medical care, e-commerce, government affairs, industrial control and other fields, the most typical of which is the financial field. In the financial field, customers' privacy data needs to be protected, while the integrity and reliability of financial data also need to be ensured.

In the specific application process, the business system needs to back up data to the backup system and restore data from the backup system when data fails or is lost. The backup system needs to support multiple backup cycles and manage and monitor the backup cycles. At the same time, the backup system also needs to support data compression and recovery to increase the speed of data backup and recovery.

In addition, the backup system also needs to support incremental backup and differential backup of data to avoid excessive backup data and improve backup efficiency. During the backup process, data also needs to be deduplicated to avoid unnecessary data redundancy and save backup space and backup resources.

4. Advantages of trusted data backup system
Compared with traditional data backup system, trusted data backup system has the following advantages:

1. Higher security: trusted Computing technology can ensure the security and reliability of backup data during transmission and processing, thereby avoiding data leakage and damage.

2. Higher reliability: Using a distributed backup solution can ensure the redundancy and reliability of data backup and avoid data unavailability caused by single points of failure.

3. Stronger scalability: The backup system supports a distributed structure, and the system can be expanded and upgraded by adding nodes.

4. Easier operation: The backup system can realize one-click backup and recovery of data, making the operation more convenient and reducing the difficulty and error rate of backup personnel.

5. Summary
With the increasing scale of data and the increasingly open system environment, the trusted data backup system constructed by trusted computing technology and distributed storage technology has become the backup system design best solution. The system can provide higher security, reliability and scalability, and provide more stable and efficient data backup guarantee for business systems.
