The backup solution includes the selection of backup hardware and backup software analysis and design. Using open source technology and network file system, to achieve the main functions of the backup management software, and using the snapshot function of VMware software, to achieve functional testing and performance testing of the backup system prototype.The core of based on the LAN backup and recovery system is backup management software which using B/S structure. Backup client use WEB interface as user interface, so there is no need to install any backup agent software, and can easily complete backup,recovery and management operations. Backup server using the Linux operating system, through the use of system's tools and backup scripts to implement the backup. The backup and recovery system provides three backup strategy: full backup,incremental backup,differential backup, and has immediate backup,automated backup,compressed backup which are as core functions network of backup system. This backup system can resume full use of existing enterprise network resources, easy to install deployment, is applicable to small and medium enterprises. |
