I would like to use Azure BLOB storage for my SharePoint online. Is it possible to use BLOB storage space to store SharePoint online documents?
How can I do that?

Hi @Daniel Maier ，

1.We can copy documents from SharePoint Online to Azure Blob Storage using Power Automate. There is a template in Power Automate called "Copy files from a SharePoint folder to a AzureBlob folder", which can copy from a shared folder in SharePoint Online to Azure storage by executing a simple flow.

2.This PowerShell script shows how to download and sync documents in a SharePoint Document Library into an Azure Storage Container using CLI for Microsoft 365 and Azure CLI commands.

 $spolHostName = "https://tenant-name.sharepoint.com"  
 $spolSiteRelativeUrl = "/sites/site-name"  
 $spolDocLibTitle = "document-library-title"  
 $azStorageAccountKey = "*****************"  
 $azStorageAccountName = "azure-storage-account-name"  
 $azStorageContainerName = "azure-storage-container-name"  
 $localBaseFolderName = "local-base-folder-name"  

 $localFileDownloadFolderPath = $PSScriptRoot  
 $spolSiteUrl = $spolHostName + $spolSiteRelativeUrl  

 $spolLibItems = m365 spo listitem list --webUrl $spolSiteUrl --title   
 $spolDocLibTitle --fields 'FileRef,FileLeafRef' --filter "FSObjType eq 0" -o json | ConvertFrom-Json  

 if ($spolLibItems.Count -gt 0) {  
   ForEach ($spolLibItem in $spolLibItems) {  
     $spolLibFileRelativeUrl = $spolLibItem.FileRef  
     $spolFileName = $spolLibItem.FileLeafRef  

     $spolLibFolderRelativeUrl = $spolLibFileRelativeUrl.Substring(0, $spolLibFileRelativeUrl.lastIndexOf('/'))  

 $localDownloadFolderPath = Join-Path $localFileDownloadFolderPath $localBaseFolderName $spolLibFolderRelativeUrl  

 If (!(test-path $localDownloadFolderPath)) {  
   $message = "Target local folder $localDownloadFolderPath not exist"  
   Write-Host $message -ForegroundColor Yellow  

   New-Item -ItemType Directory -Force -Path $localDownloadFolderPath | Out-Null  

   $message = "Created target local folder at $localDownloadFolderPath"  
   Write-Host $message -ForegroundColor Green  
 }  
 else {  
   $message = "Target local folder exist at $localDownloadFolderPath"  
   Write-Host $message -ForegroundColor Blue  
 }  

 $localFilePath = Join-Path $localDownloadFolderPath $spolFileName  

 $message = "Processing SharePoint file $spolFileName"  
 Write-Host $message -ForegroundColor Green  

 m365 spo file get --webUrl $spolSiteUrl --url $spolLibFileRelativeUrl --asFile --path $localFilePath  

 $message = "Downloaded SharePoint file at $localFilePath"  
 Write-Host $message -ForegroundColor Green  
   }  

   $localFolderToSync = Join-Path $localFileDownloadFolderPath   
 $localBaseFolderName  
   az storage blob sync --account-key $azStorageAccountKey --account-name $azStorageAccountName -c $azStorageContainerName -s $localFolderToSync --only-show-errors | Out-Null  

   $message = "Syncing local folder $localFolderToSync with Azure Storage Container $azStorageContainerName is completed"  
   Write-Host $message -ForegroundColor Green  
 }  
 else {  
   Write-Host "No files in $spolDocLibTitle library" -ForegroundColor Yellow  
 }
