问题描述

我正在尝试使用.net API startCopy将一个存储帐户中的页面Blob复制到另一个存储帐户.这两个存储帐户均为标准类型，并且源位置中存在blob.我收到以下异常详细信息的"cannotverifysourcepath"错误.

I am trying to copy a page blob in one storage account to another storage account using .net API startCopy. Both storage accounts are standard type and blob exists in source location. I am getting "cannotverifysourcepath" error with below exception details.

我希望startcopy API可以从帐户复制到另一个帐户.谁能帮我找出问题所在吗?

I was hoping that startcopy API works to copy from account to another. Can anyone please help me to figure out what's the issue here?

推荐答案

您可以尝试使用数据移动库.具体来说:

You can try using the data movement library. Specifically:

await TransferManager.CopyAsync(source, target, false);

布尔值参数指定这是否是服务端异步副本.如果是这样，则本地任务可能会在复制完成之前完成.

The boolean parameter specifies whether or not this is a service-side asynchronous copy. If it is, the local task may complete before the copy is complete.

我已经验证了source和target在不同的帐户中并且两个访问策略都是私有"的情况下可以正常工作.

I have verified that this works when source and target are in different accounts and both access policies are 'private.'
