我的公司有几个网站托管在 VPS 上,在 Linux/CentOs/WHM/CPANEL 下

我们正在寻找一种在另一台服务器上进行灾难恢复回退的方法,以防我们的 VPS 遇到问题。

我们正在检查的选项之一是将此 VPS 克隆到 Amazon AWS 中,并让它“休眠”直到我们需要它。这样我们就可以只为存储付费。当然,我打算定期更新服务器(例如每天/每周一次),以使其保持最新状态。

考虑到这一点,我想询问以下内容: - 是否可以将 VPS 服务器克隆到 AWS 中?- 与购买另一个用作镜像的 VPS 相比,它真的会为我们省钱吗(我们目前为 VPS 支付约 1000 美元/年)?- 否则 - 以可承受的成本处理此类网站镜像的最佳做法应该是什么?

谢谢尤瓦尔。

As a matter of fact a lot a companies use this kind of DR, and it is commonly called "Cold DR" (http://en.wikipedia.org/wiki/Backup_site#Cold_Sites)

You will only pay for the space reserved for your storage (S3, EBS, Glacier) and Route 53 Zones.

Just start the instances there, migrate the data you need, configure your instances properly and then stop them.

If you are using other DNS service I suggest you to migrate your DNS management to Route53, because then would be able to easily write a script to automatically change the DNS and then start your instances, or use Route 53 Health Check and DNS Failover (http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/dns-failover.html) plus a little bit o script to achieve a more automated solution.

Hope this helps.
