Azure备份以及如何执行保留策略 [英] Azure Backup and how retention policies are executed

问题描述

我对天蓝色备份有几个疑问

I had couple of question regarding azure backup

1. 什么是Azure中的增量备份.->是否将所有增量备份与完整备份合并在一起?
2. 并且按照保留策略:例如，每日保留策略-每天在特定时间(假设7天)存储的特定时间(例如4:00 PM)每天(例如今天)进行备份.那么，在7天(即第8天)之后，今天下午4点采取的备份将被删除吗?以及如何在恢复过程中备份该数据?

推荐答案

什么是Azure中的增量备份.->是否合并所有增量备份和完整备份?

what is Incremental Backup in Azure. --> Is it merge all the incremental backups together with full backup?

您是说完全备份+一天增量备份可以还原它吗?如果我理解正确，那么答案是否定的，我们应该保留所有增量备份和完整备份.

Do you mean full backup + one day incremental backup can restore it? If I understand it correctly, the answer is no, we should keep all the incremental backups and full backup.

完全备份和增量备份之间的区别，请参考此图像:

并按照保留政策:例如，每日保留政策-每天(在今天说)在特定时间(比如说)进行备份在4:00 PM)存储了特定的日期(比如说7天).所以7点以后天(即第8天)今天下午4点采取的备份会被删除吗?以及如何在恢复过程中备份该数据?

And as per retention policies: For example, Daily retention policy - Backups are taken daily(Let's say today) at specific times(let's say at 4:00 PM)stored for specific days(let's say for 7 days). So after 7 days (i.e. on the 8th day)backup taken today at 4 PM will be deleted? and how we will be able to get data of that back up during recovery?

保留策略只能应用于备份点.每个恢复点的行为都像一个完整点.

Retention policies can only be applied on backup poins. Each recovery point behaves like a full point.

因此，我们将能够使用最新的备份点恢复您的数据.

So, we will be able recovery your data with newest backup points.

更新:

关于保留策略，如果我们选择每日保留策略"，则每天进行的备份将存储7天.如果我们使用每日保留策略，Azure还将在一天之内创建两个恢复点.

About retention policy, if we select daily retention policy, backups taken daily are stored for seven days. Also Azure will create two recover points one day if we use Daily retention policy.
