Copy Blob from one storage account to another in Azure


  • I have One blob which contains My user's CVs.

    My site is live. Now i want to copy From one blob to another blob with different storage account. 

    here is my code to copy blob

    CloudStorageAccount sourceStorageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("sourceStorageConnectionString"));
    CloudStorageAccount targetStorageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("targetStorageConnectionString"));

                CloudBlobClient sourceCloudBlobClient = sourceStorageAccount.CreateCloudBlobClient();
                CloudBlobClient targetCloudBlobClient = targetStorageAccount.CreateCloudBlobClient();

                CloudBlobContainer sourceContainer = sourceCloudBlobClient.GetContainerReference(CloudConfigurationManager.GetSetting("sourceContainer"));
                CloudBlobContainer targetContainer = targetCloudBlobClient.GetContainerReference(CloudConfigurationManager.GetSetting("targetContainer"));

                // Copy each blob
                foreach (IListBlobItem blob in sourceContainer.ListBlobs(useFlatBlobListing: true))

                    Uri thisBlobUri = blob.Uri;

                    var blobName = Path.GetFileName(thisBlobUri.ToString());
                    Console.WriteLine("Copying blob: " + blobName);

                    CloudBlockBlob sourceBlob = sourceContainer.GetBlockBlobReference(blobName);
                    CloudBlockBlob targetBlob = targetContainer.GetBlockBlobReference(blobName);

                    Task task = TransferManager.CopyAsync(sourceBlob, targetBlob, true /* isServiceCopy */);


    but my concern is: If this copy operation is running and one of the Cv is updated by any user then will it be effect on live site or in copy operation???

    And also will this code is correct for copy blob?

    Please help me out for this problem..

    Thanks in advance,
