Cloud backup, as a backup method that stores data in the cloud, is gradually becoming an important trend in the field of data management. In the actual application of cloud backup, data security issues and data redundancy issues have attracted much attention. This article proposes a cloud backup solution based on SM4 symmetric encryption and redundancy detection, conducts an in-depth analysis and discussion of data security issues and data redundancy issues in cloud backup, and puts forward suggestions and solutions to deal with data security and data redundancy issues. Solutions, including SM4 encryption algorithm, redundancy detection, etc., are of great significance for understanding and solving data security issues and data redundancy issues in cloud backup.
