Embodiment Construction

[0033] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0034] The relevant concepts involved in the present invention are described below:

[0035] Backup: In order to cope with possible unexpected situations such as file and data loss or damage, the data in the electronic computer storage device is copied to a large-capacity storage device such as a magnetic tape. A copy of a program or document that is stored separately from the original text.

[0036] Disaster recovery system: In remote locations, two or more sets of IT systems with the same functions can be established, and health status monitoring and function switching can be performed between each other. When one system stops working due to accidents (such as fire...

Abstract

The embodiment of the invention discloses a method and device for disaster recovery backup facing emergency replacement. The method comprises the steps of receiving disk contents stored in an object server, processing the disk contents to be a disk mirrored volume format file, and generating a snapshot for the disk mirrored volume format file; if it is determined and learnt that the object server is subjected to service disasters, performing switching to an emergency replacement mode, starting the disk mirrored volume format file, and replacing the object server to operate an application program in the disk mirrored volume format file. By processing the disk contents stored in the object server to be the disk mirrored volume format file and then generating the snapshot, when the object server is subjected to the service disasters, switching is directly performed to the emergency replacement mode, the disk mirrored volume format file is started, and the object server is replaced to operate the application program in the disk mirrored volume format file. The disaster recovery time is short, the service interruption time is remarkably reduced, and the investment and maintenance difficulty is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a disaster recovery backup method and device for emergency replacement. Background technique [0002] When the software system crashes, the system can be rebuilt with very few steps, including system patches, application software and data reconstruction, which can improve the accuracy of recovery, shorten the recovery time, and shorten the business interruption time. This process It's called system disaster recovery. [0003] Existing system disaster recovery methods include the following four methods: [0004] (1) A common CD is used, and all systems use this CD. This CD can start the system, and can start the network at the same time, and then the backup server restores the entire hard disk content or the first primary partition content backed up in the tape library (or virtual tape library) to the disaster machine. In this way, no matter how ...
