一种异步实时的CDP机制的设计与实现
Design for Asynchronous and Real-time Remote Replication System
连续数据保护（Continuous Data Protection, CDP）是一种数据的连续时间点的保护技术，它能在故障瞬间完成任何时间点的故障恢复，达到业务的快速连续的作用。与传统的数据保护技术相比，CDP可以提供更灵活的目标恢复点和更快的目标恢复时间。本文实现了一种名为SnapCDP的基于LVM(Logical Volume Management)的CDP机制。SnapCDP是将CDP模块嵌入到LVM中来实现的。实验表明，SnapCDP可以利用较短的时间将数据恢复到用户设定的历史时间点。
ontinuous Data Protection(CDP) is a kind of the data protections technology with continuous recovery time points. It can resume data to the historical states as quickly as possible. Compared with traditional technologies, CDP can supply more flexible Recovery Point Objectives (RPO) and more actual Recovery Time Objectives (RTO).In this paper, a CDP system, named SnapCDP, is introduced. SnapCDP embeds the continuous data protection mechanism into the Logical Volume Manager. The experiments show that SnapCDP can recovery the data to any time point which users set in advance.
