摘要
为了解决目前云备份系统恢复目标时间点不连续以及恢复粒度太粗的问题,将连续数据保护技术应用到云备份系统中,提出了一种支持连续数据保护的云备份系统。本系统能够提供秒级的连续恢复时间点,且数据块级别的备份层次能够屏蔽异构平台,具有更广泛的应用前景。系统以私有云为架构基础,部署在防火墙内部,对数据安全有很高的保障。
In order to solve the current problems that the recovery time of cloud storage backup system is not continuous and the recovery granularity is too thick, this paper presents a cloud storage backup system with continuous data protection, by applying continuous data protection technology to cloud backup technology. This system that can provide second-level continuous recovery time points and block-level backup for screening heterogeneous platforms, would be used in broad range. In addition, the system, which is deployed inside the firewall, can greatly safeguard the data security due to its private cloud structure.
