持续数据保护

因此，我们谨遵CDP定义，根据实际环境的不同，采用了针对硬件、软件、误操作、病毒，自然灾难等不同因素的持续数据保护方案。

So we follow the CDP definition carefully , adopt special continuous data protection scheme that aims at different factors such as hardware , software , mis-operation , virus and natural disasters and so on .

一种持续数据保护系统的设计与实现

Design and implementation of a continuous data protection system

持续数据保护技术既可以用硬件实现也可以用软件实现，本文就是从软件实现的角度对持续数据保护技术做了研究，指出其中的关键技术，并且对性能做了详尽的分析。

Continuous data protection technology can use hardware implementation can also use software to realize , this article is from the point of view of the software implementation of continuous data protection technology , and points out that the key technology of performance , and the detailed analysis .
