Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0033] A virtual machine includes virtual resources capable of realizing computer functions, including computing, memory, network, input and output, storage, etc. During actual operation, the virtual machine can store relevant business data in storage resources. The business data in the storage resources will change, and in some cases, the business data needs to be rolled back to the state at a certain historical point in time.

[0034] A current virtual machine backtracking method...

Abstract

The invention provides a method for virtual machine backtracking after receiving the backtracking instruction to the target virtual machine, the data disk to be traced is determined, the tracing datacorresponding to the data disk is found from the pre-created tracing data, and a clone disk pointing to the tracing data is created, and the pointing relationship of the target virtual machine to thedata disk is modified to the pointing relationship to the clone disk. As can be seen, the present application can realize the backtracking at the data disk level without cloning the entire virtual machine, and the cloned disk does not actually copy the backtracking data, but redirects the backtracking data, which can not only save the backtracking time but also reduce the waste of storage resources. In addition, the present application also provides a virtual machine backtracking related device for guaranteeing the application and implementation of the method in practice.

Description

technical field [0001] The present application relates to the technical field of data backtracking, more specifically, a virtual machine backtracking method and related equipment. Background technique [0002] A virtual machine is a computer system simulated by a software program with complete hardware system functions. Like a physical computer, a virtual machine includes independent and complete machine resources, such as computing resources, memory resources, network resources, storage resources, and input and output resources. [0003] During actual operation, the business data processed by the virtual machine will change. In some cases, it is necessary to trace back the current business data to the historical business data. For example, malicious program attacks cause damage to business data, operations such as accidental deletion lead to loss of business data, frequent changes in business data require review of some business data before the change, and so on. [0004]...
