Problems solved by technology

[0005] The invention solves the problem that the system used to guide the computer to start when the application server system is restarted is inconsistent with the system used before the computer went down, so that related services, system configuration, and registry information cannot be reflected in the new system, and the application program cannot run normally.

Embodiment Construction

[0029] Such as figure 1 As shown in the figure, it shows the process of backing up application server data to the backup server storage group and creating a snapshot when the system is running normally. Wherein, the client device 2 , the application server 3 and the backup server 5 are connected through a local area network LAN 1 .

[0030] In the normal operation of the system, the following work process continues:

[0031] The backup server 5 continuously captures and replicates the source data 6 of each physical volume of the application server 3 through continuous replication technology, forms a data stream 4 through the LAN 1, and forms a data copy 7 on the physical volume of the backup server 5 .

[0032] Regularly create snapshots for the continuously changing data copies on the backup server, and create data snapshots 8 at multiple time points T1, T2, T3... on the backup server. Data snapshots 8 record the data changes from the previous snapshot to this snapshot info...

Abstract

The invention discloses a snapshot-based application server remote boot method. In the method, creating multiple data copy snapshots of the source data trend of the application server in a backup server by using a snapshot technique, and proper snapshots in the backup server, when the application server goes down, are mounted to a local disc to boot a fault server through the Ethernet or a storage area network quickly so as to restore the normal application of the fault server. In the invention, the problem of the overlong system creation or restoration of a computer operating system having a fault and the problem of a failure in the representation of related serve, system configuration and registry information and the like in a new system and a failure in the normal operation of an application, which are caused by the inconsistency between a system for booting the application server and a system used by the application server before going down during the booting of a common remote operating system are solved, and the downtime and loss are reduced to a minimum degree.

Description

technical field [0001] The invention belongs to the field of computer data storage and safety, and in particular relates to system and data recovery after a network-based computer breaks down. Background technique [0002] With the rapid popularization of computers and the wide application of the Internet in recent years, the security operation problems of various 7×24-hour services, including e-commerce and e-government affairs, have become increasingly prominent. Work abnormally, hang down, or even fail to start properly. While enterprise IT managers adopt various methods to protect data, the requirements for the continuity of business applications are also increased. After the application server goes down, the business system will be paralyzed. If the service cannot be restored quickly, it will affect customer needs. The negative impact on business and enterprise will be enormous. If the computer cannot be booted and started after the computer fails, it is necessary to ...
