容灾系统的级别

1 楼

数据级:

通过建立异地容灾中心,做数据的远程备份,在灾难发生之后要确保原有的数据不会丢失或者遭到破坏。

在数据容灾方式下,所建立的异地容灾中心可以简单地把它理解成一个远程的数据备份中心。在数据级容灾这个级别,发生灾难时应用是会中断的。

数据级容灾的恢复时间比较长,但是相比其他容灾级别来讲它的费用比较低,而且构建实施也相对简单。

数据源是一切关键性业务系统的生命源泉,因此数据级容灾必不可少。

应用级:

在数据级容灾的基础上,在备份站点同样构建一套相同的应用系统,通过同步异步复制技术,这样可以保证关键应用在允许的时间范围内恢复运行,尽可能减少灾难带来的损失,让用户基本感受不到灾难的发生,这样就使系统所提供的服务是完整的、可靠的和安全的。

业务级:

全业务的灾备,除了必要的IT相关技术,还要求具备全部的基础设施。其大部分内容是非IT系统。当大灾难发生后,原有的办公场所都会受到破坏,除了数据和应用的恢复,更需要一个备份的工作场所能够正常的开展业务。
