摘要
提出并实现了一种基于Linux的远程异步备份系统。该系统在设备驱动层监视本地服务器的写操作,并将相关信息封装成记录发送到备份网关上缓存,然后由备份网关异步地将所缓存的记录发送到远程备份服务器上,最后在远程服务器上重建写操作并提交给相应的备份分区。该系统可适应多种网络状况,对用户透明,支持Linux下的所有文件系统与存储设备,实现了对本地服务器分区或磁盘的物理备份。
This paper presents an asynchronous network backup system based on Linux. This system monitors the writing operation of local server and encapsulates the information in a record, which is sent to the backup gateway, then the writing operation is transmitted and submitted to the remote backup server asynchronously. This system implements backup in physical layer. This system can adapt to the status of network and support all the storage medias and file systems that the Linux kernel supports.
