AI Technical Summary

Technical Problem

In streamlined volumes, there is a conflict between the need for data encryption and the need for efficient use of storage resources, leading to data reading errors and wasted storage resources.

Method used

By distinguishing between full target value data blocks and non-full target value data blocks, and using different storage and processing methods, full target value data blocks are directly stored while non-full target value data blocks are encrypted, ensuring data security and improving the efficiency of storage space utilization.

Benefits of technology

It achieves the goal of ensuring data security, avoiding data block type confusion, and saving storage costs while maintaining efficient use of storage resources in thin volumes.

Abstract

The present application provides a data processing method and apparatus, a device, and a storage medium. During data processing, a first data block is processed in a corresponding processing mode on the basis of the value of data comprised in the first data block. When the first data block is a full target value data block, the first data block is directly stored in a storage space of a thin volume. When the first data block is a non-full target value data block, the first data block is encrypted to obtain a first ciphertext block, and the first ciphertext block is stored in the storage space of the thin volume. While ensuring data security, confusion between a non-full target value data block and a full target value data block caused by conversion between the full target value data block and the non-full target value data block is avoided, and while maintaining the characteristics of efficient utilization of storage resources of a thin volume, encrypted storage of service data is realized, and the utilization efficiency of a storage space is improved.
