Azure 异地复制存储以允许在次要区域中写入

[英]Azure Geo-replicated Storage to Allow Write in Secondary Region

原文 2020-12-13 08:54:51 8 1 azure/ azure-storage-blobs/ replication

Using RA-GRS Azure Storage Account, is it possible to write to a blob path in both regions?使用 RA-GRS Azure 存储帐户，是否可以在两个区域中写入 blob 路径？

We have two regions running the same data flows active-active (configured via Traffic Manager), however one legacy application used for file transfer to our on premise estate will only be available in the primary region.我们有两个区域运行相同的主动-主动数据流（通过流量管理器配置），但是用于将文件传输到我们的本地资产的一个遗留应用程序将仅在主要区域中可用。 In case of DR we will manually stand up the application in the secondary region.在 DR 的情况下，我们将在次要区域中手动启动应用程序。 (This is due to a limitation in the application itself.) （这是由于应用程序本身的限制。）

So the storage needs to be written to in both regions, but only in the primary region we will read (and delete on success) the data.因此，存储需要在两个区域中写入，但仅在主区域中，我们将读取（并在成功时删除）数据。 Does RA-GRS allow this? RA-GRS 是否允许这样做？ Some delay in the files being synced to primary region will not be a problem.同步到主要区域的文件的一些延迟不会成为问题。

Azure Storage Account RA-GRS does not offer two-way synchronization, you would need to implement a solution yourself. Azure 存储帐户 RA-GRS 不提供双向同步，您需要自己实施解决方案。 azcopy offers some functionality for doing this. azcopy 为此提供了一些功能。
