一、服务器备份
很多企业通过使用香港服务器租用的方式来部署在线业务，香港服务器通常用于执行关键任务，这意味着您租用的服务器停机，业务流程将完全停止。这就是为什么服务器租用的恢复时间目标(RTO)一定要短，或系统关闭和恢复之间的时间一定要短的原因。
就香港服务器租用的RTO而言，您应该设置备份，以基于小时而不是几天的间隔运行。我们推荐基于镜像的备份，它可以创建服务器上所有数据(应用程序、文件、操作系统等)的快照。基于映像的备份的好处是即时恢复。
我们建议您将备份存储在异地和云端。这也有助于您考虑业务连续性和灾难恢复的标准。
二、计算机备份
由于服务器备份的定义更加清晰，所有关键数据应保存在服务器上而不是单个PC上。但是，个人计算机仍然需要备份服务。
1)传统计算机备份。传统备份方式就是将计算机硬盘进行数据备份。但是，这种方式出现人为错误的风险较大大，而且可能很耗时。
2)自动云备份。自动化云备份方法比传统模式更安全，一致且更简单。
如果计算机装有QuickBooks或AutoCAD等关键系统，则应将计算机视为服务器，即基于映像的备份和简短的RTO。
三、唯一的好备份是经过测试的备份
如果备份不起作用，备份再多的数据也没有意思。因此，请注意确保您的备份由高质量的IT服务提供商设置，并要求他们确保他们时常工作。
