Backup/restore Blob in Azure

A client accidently deleted some files from a Container in Azure Blob Storage (through a CMS). Is there a way for me to within azure portal manage backup and restore of a container so I can prevent this from happening again?

Yes, you can create another storage account and copy your container blobs to it. You can use powershell to do it.

code for copy all container/blobs to another storage account:

$SourceStorageAccount = "sourceStorageAccount"
$SourceStorageKey = "sourceKey"
$DestStorageAccount = "destStorageAccount"
$DestStorageKey = "destKey"

$SourceStorageContext = New-AzureStorageContext –StorageAccountName $SourceStorageAccount -StorageAccountKey $SourceStorageKey
$DestStorageContext = New-AzureStorageContext –StorageAccountName $DestStorageAccount -StorageAccountKey $DestStorageKey

$containers = Get-AzureStorageContainer -Context $SourceStorageContext

foreach($container in $containers) {  
    New-AzureStorageContainer -Context $DestStorageContext -Name $container.name -Permission Off

    $Blobs = Get-AzureStorageBlob -Context $SourceStorageContext -Container $container.name

    #Do the copy of everything
    foreach ($Blob in $Blobs) {
       Write-Output "Moving $Blob.Name"
       Start-CopyAzureStorageBlob -Context $SourceStorageContext -SrcContainer $container.name -SrcBlob $Blob.Name `
          -DestContext $DestStorageContext -DestContainer $container.name -DestBlob $Blob.Name
    } 
}

code for copy a container to another storage account:

$SourceStorageAccount = "sourceStorageAccount"
$SourceStorageKey = "sourceKey"
$DestStorageAccount = "destStorageAccount"
$DestStorageKey = "destKey"

$containerName = 'SourceContainerName'; 

$SourceStorageContext = New-AzureStorageContext –StorageAccountName $SourceStorageAccount -StorageAccountKey $SourceStorageKey
$DestStorageContext = New-AzureStorageContext –StorageAccountName $DestStorageAccount -StorageAccountKey $DestStorageKey

New-AzureStorageContainer -Context $DestStorageContext -Name $containerName -Permission Off

$Blobs = Get-AzureStorageBlob -Context $SourceStorageContext -Container $containerName

#Do the copy of everything
foreach ($Blob in $Blobs) {
   Write-Output "Moving $Blob.Name"
   Start-CopyAzureStorageBlob -Context $SourceStorageContext -SrcContainer $containerName -SrcBlob $Blob.Name `
       -DestContext $DestStorageContext -DestContainer $containerName -DestBlob $Blob.Name
}

you can aslo backup your container in the same storage account:

$StorageAccount = "yourStorageAccount"
$StorageKey = "yourStorageKey"

$SourceContainerName = 'yourContainerName'; 
$DestContainerName = 'yourBackupContainerName';

$StorageContext = New-AzureStorageContext –StorageAccountName $StorageAccount -StorageAccountKey $StorageKey

New-AzureStorageContainer -Context $StorageContext -Name $DestContainerName -Permission Off

$Blobs = Get-AzureStorageBlob -Context $StorageContext -Container $SourceContainerName

#Do the copy of everything
foreach ($Blob in $Blobs) {
   Write-Output "Moving $Blob.Name"
   Start-CopyAzureStorageBlob -Context $StorageContext -SrcContainer $SourceContainerName -SrcBlob $Blob.Name `
       -DestContext $StorageContext -DestContainer $DestContainerName -DestBlob $Blob.Name
}
