带有存储的Azure Powershell

Question

I want to copy from Azure file share to blob and I am following below refs, and I wanted a incremental copy which is available in azcopy with not in Start-AzureStorageBlobCopy. And ofcourse Start-AzureStorageBlobIncrementalCopy wont do copy from file share to blob.

https://docs.microsoft.com/en-us/powershell/module/azure.storage/start-azurestorageblobincrementalcopy?view=azurermps-6.8.1

https://docs.microsoft.com/en-us/powershell/module/azure.storage/start-azurestorageblobcopy?view=azurermps-6.8.1

I wrote small commands,

$StorageContext = New-AzureStorageContext -StorageAccountName 'neverdelete' -StorageAccountKey 'XXX'
$Srcsh = Get-AzureStorageFile  -ShareName "filetest" -Context $StorageContext
$DestBlob = Get-AzureStorageBlob -Container "client1" -Context $StorageContext
Start-AzureStorageBlobCopy -SrcShare $Srcsh --DestContainer $DestBlob

But this throws an error below:

Start-AzureStorageBlobCopy : Cannot convert 'System.Object[]' to the type 'Microsoft.WindowsAzure.Storage.File.CloudFileShare' required by parameter 'SrcShare'. Specified method 

is not supported. At line:4 char:38 + Start-AzureStorageBlobCopy -SrcShare $Srcsh --DestContainer $DestBlob + ~~~~~~ + CategoryInfo : InvalidArgument: (:) [Start-AzureStorageBlobCopy], ParameterBindingException + FullyQualifiedErrorId : CannotConvertArgument,Microsoft.WindowsAzure.Commands.Storage.Blob.Cmdlet.StartAzureStorageBlobCopy

I dont know what I am doing wrong here and how do I script it so that it could be incremental.

Thanks, Akshay

Answer 1

You get the error because the -SrcShare parameter expects a CloudFileShare and you pass a list of AzureStorageFile / AzureStorageDirectory . Also your -DestContainer has two -- and you are missing the context.

So you could eg iterate over your AzureStorageFiles and invoke the Start-AzureStorabeBlobCopy cmdlet for each of them:

$Srcsh | ForEach-Object {
    Start-AzureStorageBlobCopy -SrcShare ($Srcsh[0] | Select-Object -ExpandProperty Share) -SrcFilePath $_.Name -DestContainer "client1" -Context $StorageContext
}

I suppose that you want to copy the files in the storage fileshare to storage container, you could try the command below.

$StorageContext = New-AzureStorageContext -StorageAccountName 'StorageAccountName' -StorageAccountKey 'xxxxx'
$Srcsh = Get-AzureStorageFile -ShareName "filesharename" -Context $StorageContext | Get-AzureStorageFile
$DestBlob = Get-AzureStorageContainer -Container "containername" -Context $StorageContext
foreach ($item in $Srcsh)
 {
    Start-AzureStorageBlobCopy -SrcFile $item  -DestContainer "DestContainername" -Context $StorageContext
 }

My fileshare:

Result in the container:

For Start-AzureStorageBlobCopy (Start-AzureStorageFileCopy), the cmdlets can only copy single File/Blob, can't copy a share/container, and the copy can't be resume if fail.

The incremental copy ( https://docs.microsoft.com/en-us/rest/api/storageservices/incremental-copy-blob ) can only copy page blob snapshot, and currently File not support it. As you say AzCopy support it, what do you means about "incremental copy"?

If you want to copy all files in the root directory in a share, you can use following command. (Please note, Get-AzureStorageFile will only get the first level file/dir in a share or dir, it won't get the files in subdir.)

Get-AzureStorageFile -ShareName $shareName -Context $StorageContext
| where {$_.GetType().Name -eq "CloudFile"} |Start-AzureStorageBlobCopy  -DestContainer $containerName -DestContext $StorageContext
-context $StorageContext

BTW, for any azure powershell problem, the formal way is to open an issue in https://github.com/Azure/azure-powershell/issues , and the proper team will follow up it.
