Remote disaster recovery system and remote disaster recovery method based on virtual machines

Abstract

The invention discloses a remote disaster recovery system and a remote disaster recovery method based on virtual machines. The system comprises a standby station and a main station in mutual connection, wherein the main station comprises a first virtual machine, a first virtual machine manager and a first virtual machine snapshot, the standby station comprises a second virtual machine manager, a second virtual machine snapshot module and a second virtual machine, and when the main station fails, a virtual machine management system of the standby station starts the last stored main use system virtual machine mirror image file, so the system can fast enter a stable work state, the virtual machine mode is used for building a backup station of a network finance information system, the repeated investment and building of backup equipment can be greatly reduced, the utilization rate of idle equipment is improved, and the building investment and the operation cost of a disaster recovery finance information system are greatly reduced. The state of the disaster recovery finance information system is stored through the virtual machine snapshot, and the disaster recovery finance information system can be automatically and remotely started in a very short time when the disaster recovery occurs.

Description

technical field [0001] The invention relates to a remote disaster recovery system based on a virtual machine and a disaster recovery method thereof. Background technique [0002] Disaster recovery technology can ensure the security of data and the uninterrupted operation of key businesses in the case of various natural disasters and man-made damage, and build a highly reliable system; the current disaster recovery system is divided according to the location of data replication, including The following categories: disaster recovery system based on storage devices, the system is implemented on a dedicated physical storage device, and the disaster recovery system based on host system software realizes data backup. [0003] Off-site disaster recovery can effectively improve the usability of the network core financial information system, but to adopt off-site disaster recovery, it is necessary to build relevant hardware devices in multiple geographical locations according to one ...

Problems solved by technology

[0003] Off-site disaster recovery can effectively improve the usability of the network core financial information system, but to adopt off-site disaster recovery, it is necessary to build relevant hardware devices in multiple geographical locations according to one or several times the network design capacity, so that the network core financial information system The construction cost of the

[0004] At present, the existing systems still have all or some of the following shortcomings. They cannot retain the running status of the application, but can only achieve data-level replication; rely on special equipment, which is expensive and has a small scope of application; rely on specialized applications, data copying, and recovery speed Slow, and the service stops for too long. In the IP-based financial information system, in order to improve the high availability of the financial information system at the core of the network under earthquakes, floods and other geographical and natural disasters, it is necessary to build disaster recovery equipment in one or more remote places. In order to realize the failure of one or more financial information systems, the backup equipment can take over the related control business

[0005] At the same time, in most normal situations, in order to ensure that the disaster recovery network financial information system can quickly take over business at any time, the disaster recovery network financial information system also needs to run normally, consuming a lot of power, air conditioning and network resources, but there is no work load, is a waste
