Copy a Blob From an Azure Datacenter to Another Using PowerShell

Copying a Blob Using Azure PowerShell

On regular occasions, I need to move blobs from one storage account to another. And there are a couple of ways that we can do this. The first is to download the blob and upload it to a new location. In most scenarios, this is not what we want. This post demonstrates how to create an Azure Storage Blob Copy job and how to monitor its progress.

Setup The Destination Storage Account

$destinationStorageAccountName = 'westusbrisebois'

New-AzureStorageAccount -StorageAccountName $destinationStorageAccountName `
                        -Location 'West US'

$container = 'vhds'
 
# Destination Storage Account Context

$destinationKey = (Get-AzureStorageKey -StorageAccountName $destinationStorageAccountName).Primary
$destinationContext = New-AzureStorageContext –StorageAccountName $destinationStorageAccountName `
                                              -StorageAccountKey $destinationKey 
 
# Create the destination container

New-AzureStorageContainer -Name $container `
                          -Context $destinationContext

Copy Blob to The Target Storage Account

# Source Storage Account Context

$sourceStorageAccountName = "eastusbrisebois"
$sourceKey = (Get-AzureStorageKey -StorageAccountName $sourceStorageAccountName).Primary
$sourceContext = New-AzureStorageContext –StorageAccountName $sourceStorageAccountName `
                                         -StorageAccountKey $sourceKey

# Find the VHDs to copy

Get-AzureStorageBlob -Container 'vhds' `
                     -Context $sourceContext

   Container Uri: https://eastusbrisebois.blob.core.windows.net/vhds

Name                      
vm-os-disk.vhd     PageBlob  10737418752

# Create the Blob Copy Job

$blobName ='vm-os-disk.vhd'

$blobCopy = Start-AzureStorageBlobCopy -DestContainer $container `
                                       -DestContext $destinationContext `
                                       -SrcBlob $blobName `
                                       -Context $sourceContext `
                                       -SrcContainer $container
 
# Blob Copy Progress

while(($blobCopy | Get-AzureStorageBlobCopyState).Status -eq "Pending")
{
    Start-Sleep -s 30
    $blobCopy | Get-AzureStorageBlobCopyState
}
