Abstract

The invention provides a virtualization-based remote data recovery method and a virtualization-based remote data recovery device. The method comprises the following steps of: configuring a production disk and a copy disk; binding the production disk with the copy disk so as to form a common logic body and presenting the logic body in the form of a virtual disk; establishing the corresponding relation between the production disk and the physical memory position of the copy disk; redirecting the input and output of the virtual disk; after the virtual disk receives an initialization command, copying data of the production disk onto the copy disk according to the corresponding relation; after a data recovery command is received, copying data of the copy disk onto the production disk according to the corresponding relation; and after a data read-write command is received, performing data read-write operation according to a redirected read-write position. In the method, data can be used normally in a data recovery process and data security can be ensured.

Description

technical field

[0001] The invention relates to the computer field, in particular to a data remote recovery method and device. Background technique

[0002] With the rapid development of the digital age, the growth of modern data and the security of data have attracted the attention of most users of data. Usually, under the deployment of the existing data storage environment, remote disaster recovery functions are equipped, but Once the data in the production center is lost, the data has to be recovered through remote data disaster recovery. It may take more than ten hours or even days for a medium-sized data center to recover data. During the replication process, The data cannot be used; under the existing data storage deployment, the free switching between the production center and the replication center cannot be realized, which will bring huge losses to the economy.

[0003] Therefore, how to use the data normally and ensure the security of the data during the data reco...
