Description

Technical Field

[0001] The present invention belongs to the field of remote disaster recovery, and more specifically, it particularly relates to a remote disaster recovery system based on a virtual machine, and also relates to a remote disaster recovery method based on a virtual machine. Meanwhile, the present invention also relates to a remote disaster recovery device based on a virtual machine. Background Art

[0002] Remote disaster recovery, as the name implies, is to build one or more sets of the same application or database in different regions to take over immediately after a disaster. Remote disaster recovery is a data security strategy that cannot be ignored. With the expansion of the scale of enterprises, the data backup in the original consciousness of users can no longer meet the needs of key businesses for system availability, real-time performance, and security. More importantly, the backed-up data is often destroyed due to various factors, such as earthquakes, fires, and losses. The emergence of remote disaster recovery solutions can further improve the disaster recovery capabilities of data against various possible security factors by establishing backup systems in different locations.

[0003] In the existing off-site disaster recovery system, when a client fails, the operator needs to copy the previously backed-up data before restoring business services. It takes a lot of time to completely copy this data, resulting in a long service suspension, which brings inconvenience to users. Summary of the invention

[0004] The purpose of the present invention is to provide a remote disaster recovery system, method and device based on virtual machines to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A remote disaster recovery system based on a virtual machine, comprising a remote disaster recovery management module, a first virtual machine processing module, a second virtual machine processing module and a client;

[0007] The client includes a data processing module, a data upload module and a virtual machine snapshot module. The virtual machine snapshot module is used to intercept the files that need to be backed up on the data processing module, and save them in the form of files through virtual images, and then upload them to the remote disaster recovery management module through the data upload module;

[0008] The first virtual machine processing module is deployed on a first physical host;

[0009] The second virtual machine processing module is deployed on a second physical host;

[0010] The off-site disaster recovery management module is used to process the data transmitted by the client. First, the off-site disaster recovery management module will search the database, and then divide the transmitted data into two categories, one is a type of file associated with the original database, and the other is a type of file that is not associated with the original database. Then, the type of file is transmitted to the first virtual machine processing module, and the type of file is transmitted to the second virtual machine processing module. When a customer data failure occurs, the second virtual machine processing module is enabled to replace the client.

[0011] Preferably, the remote disaster recovery management module is provided with a data storage module for storing the database.

[0012] Preferably, the first physical host, the second physical host and the remote disaster recovery management module are all deployed in different areas.

[0013] A remote disaster recovery method based on a virtual machine comprises the following steps:

[0014] S1. Create a virtual machine environment on the client and include the application content to be protected in the virtual machine environment;

[0015] S2, intercept the files that need to be backed up on the data processing module through the virtual machine snapshot module, and then upload them to the remote disaster recovery management module through the data upload module;

[0016] S3, the remote disaster recovery management module is used to process the data transmitted by the client. First, the remote disaster recovery management module searches the database and then divides the transmitted data into two categories: one is the first type of files related to the original database, and the other is the second type of files not related to the original database;

[0017] S4, a type of file is associated with files in the database and therefore cannot be stored separately, so it is stored in the first virtual machine processing module;

[0018] S5. The second-category file is not related to the files in the database and can be regarded as a new file. Since its date is earlier, it is stored separately in the second virtual machine processing module;

[0019] S6. After receiving the information about the client failure, the second virtual machine processing module is enabled to replace the client. The data stored in the second virtual machine processing module are all new data with an early date and no association with the old data. Therefore, they can be easily called, thereby quickly restoring part of the business processing capacity, and then copying the data in the first virtual machine processing module.

[0020] A remote disaster recovery device based on a virtual machine comprises any one of the remote disaster recovery systems based on a virtual machine described above.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention sets up an off-site disaster recovery management module, a first virtual machine processing module and a second virtual machine processing module. The off-site disaster recovery management module, the first virtual machine processing module and the second virtual machine processing module all have the internal capacity to store data. The data can be processed by the off-site disaster recovery management module, and the data can be divided into one category of data and two categories of data. The one category of files is related to the files in the database and cannot be stored separately, and is stored at the first virtual machine processing module. The second category of files is not related to the files in the database and can be regarded as new files and can be stored separately, and is stored at the second virtual machine processing module. When a client fails, the second virtual machine processing module is enabled to replace the client to quickly restore a part of the business processing capacity, and then the data at the first virtual machine processing module is copied, which is more convenient to use.
