Example Embodiment

[0014] see figure 1 , is the system structure diagram of the cloud storage system under the preferred embodiment of the present invention. The cloud storage system 1 includes a global scheduling layer 10 and a cloud storage layer 20 . The global scheduling layer 10 is composed of at least one backup server. The cloud storage layer 20 is composed of at least one cloud storage node A, B, ..., N, and the cloud storage nodes A, B, ..., N are interconnected through a network. Each cloud storage node A, B, . . . , N of the cloud storage layer 20 is connected to the global scheduling layer 10 through an Inter Cloud Management System (Inter Cloud Management System).

[0015] Each cloud storage node is a physical host with several logical volumes. Each cloud storage node can run multiple virtual machines (Virtual machines). For example, cloud storage node A runs VM1 and VM2; cloud storage node B runs VM3 and VM4. Each virtual machine can run on multiple logical volumes.

Abstract

A backup management system includes a backup manager and a number of agents. Each of the agents is in communication with the backup manager and with each other through a network. Each of the agents includes at least one virtual machine (VM). Any agent of the number of agents can send a backup request to the backup manager when the agent needs to back up the at least one VM. The backup manager can instruct the agent how to back up the at least one VM to another agent of the number of agents.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an incremental backup system and method for a cloud storage system. Background technique [0002] When the existing cloud storage system backs up the VM data of the virtual machine of the cloud storage node, it generally backs up the VM data as a whole, and when backing up again, it still backs up the VM data as a whole. For example, in the case of 1G of VM data, it is necessary to back up all the 1G files again when backing up again. If only a small part of the VM data is modified, it still takes a lot of time to back up all the VM data, wasting time and resources. Contents of the invention [0003] The invention provides an incremental backup system and method. [0004] An incremental backup system in a cloud storage system runs on a cloud storage layer of the cloud storage system, and the cloud storage layer is composed of at least one cloud storage node interconnecte...
