假设您的存储帐户类型为General Purpose v2 (GPv2)或Blob Storage，则实际上您不必自己做任何事情. Azure存储可以为您做到这一点.

Assuming your storage account's type is either General Purpose v2 (GPv2) or Blob Storage, you actually don't have to do anything by yourself. Azure Storage can do this for you.

您将使用Blob Lifecycle Management并在其中定义一个策略，以删除blob(如果它们已超过30天)，Azure存储将为您处理删除问题.

You'll use Blob Lifecycle Management and define a policy there to delete blobs if they are older than 30 days and Azure Storage will take care of deletion for you.
