AWS RDS 在创建时不断备份我的服务器

Question

我正在使用 Amazon CloudFormation 创建一个包含 EC2 和 RDS（Postgres 9.4.4、5gb、db.m1.small）的堆栈。RDS 实例一启动就启动备份。

如何阻止 RDS 在启动时对其进行备份？

这是 Postgres 日志：

Web GUI 上的“警报和最近事件”面板显示：

Answer 1

在 RDS 实例控制面板中设置维护和备份时段。一些信息可以在这里找到。

在我能看到的任何地方都没有记录这种“创建时备份”行为。它可能是自动的并且无法更改。

为什么要创建如此多的数据库或如此频繁地停止/启动数据库，这很重要？一些背景可以让您更容易获得帮助。我创建了一次 RDS 数据库，它每晚都会在我的备份窗口中备份。
