从Azure文件复制到BLOB

Question

Azure是否有办法在存储容器之间移动文件而无需将其下载回您的笔记本电脑？我尝试了AzCopy，但似乎正在下载然后重新上传文件。

Answer 1

Azcopy确实提供了server-side copy的功能。它实际上是默认行为。你可以找到一个here的例子：AzCopy /Source:https://myaccount.blob.core.windows.net/mycontainer1 /Dest:https://myaccount.blob.core.windows.net/mycontainer2 /SourceKey:key /DestKey:key /Pattern:abc.txt

但是，请注意：由于您基本上免费获得所需的计算作为Azure的备用容量，因此您无法获得任何性能SLA。因此，大多数情况下这比使用同一Azure区域中的快速VM并使用所谓的同步副本（下载和上传以复制，使用zcopy中的/SyncCopy参数）慢。

所以：如果你有时间和省钱，请使用服务器端副本。如果您希望快速完成复制，请使用/ SyncCopy

你可以使用Runbook来实现这一目标。这是微软网站上一篇文章的链接，可以完成此任务;

这里是相关代码，稍加修改以使ResourceGroup成为变量。

$primary = Get-AutomationVariable -Name 'Log-Storage-Primary'
$secondary = Get-AutomationVariable -Name 'Log-Storage-Secondary'
$ResourceGroupName = Get-AutomatioNVariable -Name 'LogStorageResourceGroup'

$Conn = Get-AutomationConnection -Name AzureRunAsConnection
Add-AzureRMAccount -ServicePrincipal -Tenant $Conn.TenantID -ApplicationId $Conn.ApplicationID -CertificateThumbprint $Conn.CertificateThumbprint

$primarykey = Get-AzureRmStorageAccountKey -ResourceGroupName $ResourceGroupName -Name $primary
$secondarykey = Get-AzureRmStorageAccountKey -ResourceGroupName $ResourceGroupName -Name $secondary

$primaryctx = New-AzureStorageContext -StorageAccountName $primary -StorageAccountKey $primarykey.Key1
$secondaryctx = New-AzureStorageContext -StorageAccountName $secondary -StorageAccountKey $secondarykey.Key1

$primarycontainers = Get-AzureStorageContainer -Context $primaryctx

# Loop through each of the containers
foreach($container in $primarycontainers) {
    # Do a quick check to see if the secondary container exists, if not, create it.
    $secContainer = Get-AzureStorageContainer -Name $container.Name -Context $secondaryctx -ErrorAction SilentlyContinue

    if (!$secContainer) {
        $secContainer = New-AzureStorageContainer -Context $secondaryctx -Name $container.Name
        Write-Host "Successfully created Container" $secContainer.Name "in Account" $secondary
    }

    # Loop through all of the objects within the container and copy them to the same container on the secondary account
    $primaryblobs = Get-AzureStorageBlob -Container $container.Name -Context $primaryctx
    foreach($blob in $primaryblobs) {
        $copyblob = Get-AzureStorageBlob -Context $secondaryctx -Blob $blob.Name -Container $container.Name -ErrorAction SilentlyContinue

        # Check to see if the blob exists in the secondary account or if it has been updated since the last runtime.
        if (!$copyblob -or $blob.LastModified -gt $copyblob.LastModified) {
            $copyblob = Start-AzureStorageBlobCopy -SrcBlob $blob.Name -SrcContainer $container.Name -Context $primaryctx -DestContainer $secContainer.Name -DestContext $secondaryctx -DestBlob $blob.Name
            $status = $copyblob | Get-AzureStorageBlobCopyState

            while ($status.Status -eq "Pending") {
                $status = $copyblob | Get-AzureStorageBlobCopyState
                Start-Sleep 10
            }
            Write-Host "Successfully copied blob" $copyblob.Name "to Account" $secondary "in container" $container.Name
        }
    }
}
