配置 Amazon RDS 实例时备份窗口持续时间设置意味着什么?
What does the backup window duration setting mean when configuring an Amazon RDS instance?
推荐答案
Backup window 并没有专门询问开始备份的时间，而是询问 aws 可以触发的时间段备份.所以基本上它要求备份窗口时间.这就是为什么它有 2 个字段1. StartTime: 什么时候可以开始备份过程.2. Duration:进程必须开始备份的时间窗口.
Backup window doesn't specifically ask for the time when to start take backup but instead ask for time period in which aws can trigger backup. So basically it's asking for backup window time. That's why it has 2 fields 1. StartTime: When can the process of backup be started. 2. Duration: time window in which process must start to take backup.
E.G
如果我设置了开始时间: 5:30 和 duration: 30mints
if I set start time: 5:30 and duration: 30mints
备份可以在 5:30 到 6:00 之间的任何时间开始.
Backup can start at anytime between 5:30 to 6:00.
