Complete business data backup strategy in mobile ad-hoc network

Abstract

The invention relates to a complete business data backup strategy in a mobile ad-hoc network. The strategy mainly includes the following steps: 1) distributed storage of business data, 2) collection of business backup data, and 3) acquisition of the business backup data. The strategy is to provide the mobile ad-hoc network with a business data backup center having high-performance large-capacity data storage and data packet transmit-receive functions; the strategy has a function of backup endpoint continuous transmission, and when the network is congested, the backup is interrupted; when the network returns to normal, the backup can be automatically restarted from the interruption and continues to be performed; a multi-level index storage algorithm is adopted. The strategy achieves recovery of small particle data, minimizes impacts on a system and greatly improves recovery speed, and meanwhile, backup success rate and storage efficiency of backup data are improved.

Description

technical field [0001] The invention belongs to the technical field of storage and relates to a complete service data backup strategy in a mobile ad hoc network. Background technique [0002] In today's information age, data and information have gradually become the business foundation and economic lifeline of all walks of life. It is especially important to obtain complete business data backup and data recovery for business data loss during the transmission of business data. [0003] With the rapid development of computer technology, more and more enterprises use computer systems to handle daily business. I believe that many enterprise information management system centers have had such an experience. The data that took a long time to build up was suddenly destroyed due to unpredictable system downtime, hard disk damage, or virus damage. once. To prevent these disasters, the best solution is to do data backup in advance. Data backup is a very important task in system man...

Problems solved by technology

[0005] The backup measures currently used generally include disk mirroring, disk array, dual-machine fault tolerance, etc., but these measures are all hardware-level backups. From a logical point of view, there is actually only one copy of data, so these measures are harmful to system damage and data logic damage. Powerless, if data errors occur, these errors are quickly replicated everywhere
