为什么 Digital Ocean Discourse 快照如此庞大？

支持 安装
1

我刚刚注意到，我在 Digital Ocean 实例上为 Discourse 论坛创建的快照每个都超过 10GB。而这些论坛实际上没有任何帖子或用户（我创建了论坛，创建了快照，然后销毁了实例）。

这可能是一个愚蠢的问题，但它们为什么这么大？

A digital Ocean snapshot will always be the size of the disk. And that is a server provider feature, it has nothing to do with Discourse.

If you want to preserve Discourse state in a smaller file, use the Discourse backups, available in the admin panel.

Remember that the 1GB install includes a 2GB swap, so you’re snapshotting OS+Discourse+Swapfile.

Why are you taking a snapshot though?

I don’t need the forum online at the moment so I destroyed the droplet to save money. I created the snapshot so I could easily recreate the droplet when I want to put the forum back online. Is there a better way to do this?

@michaeld 在执行此操作时，恢复前是否需要更新任何 DNS 设置？

我认为是的，否则恢复操作会将你的主机名重写为论坛的临时 URL。

或者，你也可以在恢复后更改它（停机时间更短），然后将 URL 重新映射回原始地址。
