Method, system and apparatus for implementing failure restoration and data backup

Abstract

The present invention, pertaining to the field of communication, discloses a method for realizing fault recovery and data backup, a system and an apparatus thereof. Wherein, the method comprises the steps of starting a recovery tool, the recovery tool loading a customized root file system, establishing a pre-boot execution environment (PXE) support service, a file transmission service and a disk image management service, wherein, the PXE support service and the file transmission service are used for supporting the device to be recovered to realize the starting of an operating system through a network, and the disk image management service is used for performing disk image backup and/ or a recovery operation to the device to be recovered; after receiving an information that the starting of the operating system through a network by the device to be recovered is successful, remotely logging in the device to be recovered, and performing disk image backup and/ or a recovery operation to the device to be recovered by the disk image management service. When the device to be recovered is not configured with a CD-ROM, a display and a keyboard, the fault recovery of the device can be realized rapidly by using the method, and also the data backup is realized, therefore, time cost by the fault recovery of the device to be recovered is greatly shortened.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, system and device for realizing fault recovery and data backup. Background technique [0002] Many network element devices in the communication field cannot manage and maintain themselves without BAM (Back Administrate Module, background management module) / OMU (Operate and Maintain Unit, operation and maintenance unit). Usually, BAM / OMU is equipped with peripheral devices , such as optical drives, keyboards, and monitors. When the BAM / OMU fails and needs to be restored, maintenance personnel use the configured optical drives, keyboards, and monitors to use the operating system installation CD to reinstall the operating system for the BAM / OMU. Restoration of a faulty BAM / OMU, but this method is complex and error-prone, and requires high quality maintenance personnel.

[0002] Many network element devices in the communication field cannot manage and maintain themselves without BAM (Back Administrate Module, background management module) / OMU (Operate and Maintain Unit, operation and maintenance unit). Usually, BAM / OMU is equipped with peripheral devices , such as optical drives, keyboards, and monitors. When the BAM / OMU fails and needs to be restored, maintenance personnel use the configured optical drives, keyboards, and monitors to use the operating system installation CD to reinstall the operating system for the BAM / OMU. Restoration of a faulty BAM / OMU, but this method is complex and error-prone, and requires high quality maintenance personnel. In addition, because the operating system needs to be reinstalled, this method takes a long time, usually more than 1 hour. And it is very likely to cause the loss of system data, error logs and other information

[0003] In addition, the existing technology also provides a method for recovering BAM / OMU faults: before the BAM / OMU leaves the factory or is put into use, use the preset commercial GHOST software to pre-reserve the disk image on the hard disk of the BAM / OMU, When the BAM / OMU fails, the maintenance personnel start the commercial GHOST software through the optical drive configured by the BAM / OMU, and read the disk image reserved in the disk for recovery. Compared with the previous method, this method can effectively save the recovery time occupied by the failure. However, the user needs to purchase additional commercial GHOST software, and because this method needs to reserve the disk image in advance, it occupies the disk space of the BAM / OMU hard disk, and as the more important BAM / OMU in communication equipment, The hard disks used are usually more expensive. Therefore, the method for realizing BAM / OMU failure recovery is relatively expensive. More importantly, this method does not solve the problem of losing information such as data and error logs of the failed device.

[0004] When the inventor realizes the present invention, it is found that no matter which of the above methods is used, when the BAM / OMU is restored to a fault, it needs to be realized through the external equipment specially configured by the BAM / OMU, such as an optical drive, a keyboard and a display. However, many manufacturers currently Considering production cost, transportation, etc., the configuration of peripheral devices is simplified when BAM / OMU leaves the factory. Therefore, there is no set of rules on how to implement fault recovery for BAM / OMU without optical drive, monitor and keyboard. It is an effective method, and it has not effectively solved the problem of loss of data, error logs and other information of the faulty device
