[英]Aurora MySql DB backup size increased drastically

原文 2019-05-17 08:58:41 8 2 mysql/ amazon-rds/ amazon-aurora

I am running Aurora MySql Engine version 5.6.10a in the production environment.我在生产环境中运行 Aurora MySql 引擎版本 5.6.10a。 Automated DB snapshot size on 9th May was 120 GB and this snapshot size increased by 27 GB to 147 GB. 5 月 9 日的自动数据库快照大小为 120 GB，此快照大小增加了 27 GB 至 147 GB。 I have checked that DB size did not increase even by 1 GB.我检查过 DB 大小甚至没有增加 1 GB。 I looked on the inte.net for the reason why this happened but got nothing.我在 inte.net 上查看了发生这种情况的原因，但一无所获。

Graph for snapshot size for the last two weeks as:过去两周的快照大小图表如下：

It's pretty consistent till 9th May and after 10th May.直到 5 月 9 日和 5 月 10 日之后，它都非常稳定。 Does anyone have insight into this issue?有没有人了解这个问题？

There is bug in aurora storage provisioning, we have also faced the same issue for one of our client. aurora 存储配置中存在错误，我们的一位客户也面临同样的问题。 In our case the storage grew from 17gb to 22000 gb in 15 days where db size was just 16gb.在我们的案例中，存储在 15 天内从 17GB 增长到 22000GB，而数据库大小仅为 16GB。 We were charged a lot for that period, you can connect to aws support for the resolution of this problem.那段时间我们被扣了很多钱，你可以连接到aws support来解决这个问题。

How were you checking you snapshot size? 你是如何检查快照大小的？ One possibility is that may have configured daily backups or so, which might be the reason why your total backup size is growing. 一种可能是可能已经配置了每日备份，这可能是您的总备份大小增加的原因。 Would love to help out more if you can provide more details on the number of snapshots, how you were checking the size of the cluster and the snapshot etc. 如果您可以提供有关快照数量，如何检查群集大小和快照等的更多详细信息，愿意提供更多帮助。
