提出了一种网络备份系统的数据高速缓存方法,可用于本地数据带宽大于备份线路带宽的备份系统中,尤其是基于Internet的备份系统。该方法通过在本地服务器上部署高速缓存器来暂存服务器的变化数据,并在稍后通过备份线路将缓存的数据发送到远程服务器进行备份。
This paper proposed a method for caching data in the network backup system.This method could be implemented in the backup system of which the data bandwidth was exceeding the network bandwidth.Especially,the backup system was based on Internet.First of all,a high speed buffer was deployed in the local server to cache the changing data.And then the cached data was sent to the remote server through the backup transmission line.
