amazon-web-services - Amazon Aurora 快照备份是完整的还是增量的？

Question

RDS快照备份第一次是全量备份，第二次快照是增量备份。我可以在以下文档中找到相关信息。

https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_WorkingWithAutomatedBackups.html

The first snapshot of a DB instance contains the data for the full DB instance. Subsequent snapshots of the same DB instance are incremental, which means that only the data that has changed after your most recent snapshot is saved.

我想知道Aurora的快照拍摄是完整备份还是差异备份。有没有人有这方面的任何信息？

我已经检查了手册中的以下内容，但我无法确认 Aurora 的快照是否适用于此文本。

https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Aurora.Managing.Backups.html

Aurora backs up your cluster volume automatically and retains restore data for the length of the backup retention period. Aurora backups are continuous and incremental so you can quickly restore to any point within the backup retention period.

而且，我检查了下面的 AWS re:Invent 2019 Material 。我想在每个段(每 10GB 保护组)拍摄完整图像快照，这样对吗？

AWS 总是在增量快照上工作。即使你拍摄 EBS 卷快照。它也会是增量的。

这是 aws 文档的链接。请在本页搜索单词增量
