How do I create a copy of an existing file in an Azure Blob Storage container using code? I'm using the WindowsAzure.Storage NuGet package to handle all operations related to my Azure Blob Storage.

To be 100% clear, I'm trying to create a complete and separate copy of a file that's already been uploaded to a container on Azure Blob Storage. I also want to give the file a new name in the process.

Purely in code, you'll want to use StartCopyAsync() a method on CloudBlockBlob, to start the copy process.

One simple way is to use a logic app that triggers on a blob being created that will then copy the blob.

If you want to get more sophisticated, you can do a function app.

yeah easiest way indeed :-)
Correct me if I'm wrong but I think this is a really good way if I don't want my app involved in the copy process. If I use StartCopyAsync(), I think I'm essentially creating a file stream in to my app, then creating a copy streaming out the bits out of my app. Am I getting it right?
@Sam - no, there is no bits streaming to and from your app. The copy is done within Azure Storage itself, which is initiated via the call to StartCopyAsync().
