Start-AzureStorageBlobCopy fails to copy vhd

Here is the code:

$sas = Grant-AzureRmDiskAccess -ResourceGroupName $diskResourceGroup -DiskName $diskName -DurationInSecond 3600 -Access Read

$storageAccountKey = (Get-AzureRmStorageAccountKey -Name $storageAccount -ResourceGroupName $storageAccountResourceGroup)[0].Value
$destContext = New-AzureStorageContext -StorageAccountName $storageAccount -StorageAccountKey  $storageAccountKey

$checkContainer = Get-AzureStorageContainer -prefix $blobContainerName -Context $destContext

Start-AzureStorageBlobCopy -AbsoluteUri $sas.AccessSAS -DestContainer $blobContainerName -DestContext $destContext -DestBlob $blobName -Force
Get-AzureStorageBlobCopyState -Container $blobContainerName -Blob $blobName -Context $destContext -WaitForComplete

I'm copying a 256GB data disk to blob for DR exercises and it fails with the following log:

[18:44:22][Step 7/12] Start Copy of VM to storage [18:44:23][Step 7/12] [18:44:23][Step 7/12] ICloudBlob : Microsoft.WindowsAzure.Storage.Blob.CloudPageBlob [18:44:23][Step 7/12] BlobType : PageBlob [18:44:23][Step 7/12] Length : -1 [18:44:23][Step 7/12] ContentType : [18:44:23][Step 7/12] LastModified : 9/8/2018 10:44:22 PM +00:00 [18:44:23][Step 7/12] SnapshotTime : [18:44:23][Step 7/12] ContinuationToken : [18:44:23][Step 7/12] Context : Microsoft.WindowsAzure.Commands.Storage.AzureStorageContext [18:44:23][Step 7/12] Name : some-data-disk.vhd [18:44:23][Step 7/12] [19:43:50][Step 7/12] [19:43:50][Step 7/12] CopyId : 36d3af59-ce10-4e7c-9b98-cb7ab50d1bb7 [19:43:50][Step 7/12] CompletionTime : 9/8/2018 11:43:49 PM +00:00 [19:43:50][Step 7/12] Status : Failed [19:43:50][Step 7/12] Source : https://md-zdj0tc3ldgbq.blob.core.windows.net/px2lhh4 [19:43:50][Step 7/12] e75-b63db649096c&sig=NsbVUO5+LQoUnIvCFMKJcKYSJ9DlI7m/ [19:43:50][Step 7/12] BytesCopied : 75310645760 [19:43:50][Step 7/12] TotalBytes : 274877907456 [19:43:50][Step 7/12] StatusDescription : 403 AuthenticationFailed "Copy failed when reading [19:43:50][Step 7/12] the source."

It creates a 0 byte blob that is unusable. This used to work before. Does anyone have insight into this error. Should I not be doing this? Is there a better way? Thanks!

I believe the upload is failing due to the fact the file is only available for 3600 seconds:
$sas = Grant-AzureRmDiskAccess -ResourceGroupName $diskResourceGroup -DiskName $diskName -DurationInSecond 3600 -Access Read

Changing the amount of time that the file is readable for should solve your problem.

But according to the amount of data backed up, it should take this script 4 hours to back up my drive. Is there a better/faster method?

In this case, you could try to use Azcopy to copy blobs in Blob storage. For very large amounts of data, you can also Azure Import/Export.

Can I migrate VHDs from one region to another without copying?
