Disaster recovery backup system based on virtual machine

Abstract

The invention relates to a disaster recovery backup system based on a virtual machine. The system comprises a deploying management module, a monitoring management module, a disaster recovery management module, a virtual machine deploying module, a virtual machine migration module and a virtual machine backup module. The deploying management module, the monitoring management module, the disaster recovery management module and the virtual machine migration module are connected in sequence. The virtual machine migration module and the virtual machine backup module are connected with a virtual resource pool respectively. The virtual resource pool is connected with the virtual machine deploying module. The virtual machine backup module comprises a copy server submodule, a copy engine submodule, a heartbeat detecting submodule and an external equipment buffering submodule. The copy server submodule and the copy engine submodule are used for transmitting a control system process. The external equipment buffering submodule comprises network buffering and peripheral disk storing buffering. Compared with the prior art, the fact that data are not lost, and applications are ceaseless is guaranteed, a user can have data which can be recovered at a crucial time, and customer production applications are ceaseless.

Description

[technical field] [0001] The invention relates to the technical field of virtualized disaster recovery, in particular to a virtual machine-based disaster recovery backup system. [Background technique] [0002] At present, according to the level of disaster recovery implementation, the disaster recovery system can be divided into data disaster recovery, application disaster recovery and business disaster recovery. Due to the early start of research on data disaster recovery and application disaster recovery, practical systems are already available. The so-called business disaster recovery is to decompose the business into finer-grained applications. When a disaster occurs, the business can be reorganized to ensure the continuity of the business. After the business is decomposed, the application's demand for physical computing resources is reduced. At the same time, the performance of the single computing system hardware is getting higher and higher, wasting computing resourc...

However, the customer's production environment is not constant. Sometimes adding a memory stick or a hard disk has no effect on data replication, but when data is relocated, it may be due to the difference in the underlying hardware architecture. s failure

In fact, whether it is a relatively high-end SAN-based data replication method or a relatively simple file replication, the pursuit of the degree of data security protection ignores the possibility of ensuring data reversion, and some data that cannot be relocated even if No amount of loss can b
