Abstract

The invention provides a snapshot processing method and a snapshot processing device. The snapshot processing method comprises the steps that XOR operation is performed on metadata currently stored ina base volume and complete metadata, corresponding to a previous snapshot volume, of the base volume; compression operation is performed on a result obtained through XOR operation; and a result obtained through compression operation is recorded, and a snapshot volume of the metadata currently stored in the base volume is obtained. The snapshot processing method and the snapshot processing deviceare beneficial for saving storage space of snapshots.

Description

technical field [0001] The present application relates to the field of storage, and more specifically, to a snapshot processing method and a snapshot processing device. Background technique [0002] Cloud storage is a technology extended and developed from the concept of cloud computing. It refers to the collection of a large number of different types of storage devices in the network through application software through functions such as cluster applications, grid technology, or distributed file systems. Work together to jointly provide data storage and business access functions. [0003] When the core of cloud computing system computing and processing is to store and manage a large amount of data, a large number of storage devices need to be configured in the cloud computing system. In other words, a cloud computing system needs a cloud storage system that can efficiently manage storage space and data and read them quickly. [0004] An indispensable function in cloud sto...
