基于云计算的数据容灾备份方案

Data Disaster Recovery Backup Solution Based on Cloud Computing

自然灾害发生时,如何减少数据丢失是数据容灾备份的重要研究内容。传统的容灾备份方案主要是通过人工的方式对存储的数据进行备份,这类方案最大的缺点就是不能动态快速地响应数据丢失的情况。基于云计算的数据备份方法是一种新的数据存储方法。该方法通过互联网将服务器互联,将数据分散存储在各个数据分中心,具有数据备份和实时共享的功能。结合该技术特点,本文提出了一种基于云计算的数据容灾备份方案,当灾祸发生导致数据丢失时,该方案能够快速应急响应,并且动态恢复丢失的数据,减少因数据缺失带来的社会经济影响。

How to reduce data loss is an important research content of data disaster recovery and backup, when natural disasters occur. Traditional disaster recovery backup solutions mainly use manual methods to back up stored data, the biggest disadvantage of such solution is that they cannot dynamically and quickly respond to data loss. Cloud computing-based data disaster recovery and backup strategy is a new solution on data storage. This method connects the servers through the Internet, stores the data in each data sub center, and has the function of data backup and real-time sharing.Combining the technical characteristics of cloud computing, this paper proposes a cloud computing-based data disaster recovery backup solution, when the disaster occurs and results in data loss, this solution can provide a quick emergency response, dynamically recover lost data and reduce the society and economic impact caused by data loss.
