What is AzCopy?

AzCopy is a command-line utility designed for copying data to and from Microsoft Azure Blob, File, and Table storage. Ideal for bulk transfers and automations, it provides robust functionality with optimal performance. Here’s what makes AzCopy a go-to tool for many:


  • Data Transfer: AzCopy supports copying data between containers, accounts, or even different types of storage (e.g., from Blob to File).
  • Parallel Processing: With the ability to process multiple files simultaneously, AzCopy significantly reduces transfer time.
  • Incremental Copy: By copying only the data that has changed, AzCopy offers an efficient way to manage updates.

Example of Using AzCopy:

azcopy copy '' 'C:\local\path' --recursive

This example demonstrates how AzCopy can recursively copy data from a blob container to a local directory, offering a quick and intuitive solution for backups or migration tasks.

What is Azure File Sync?

Azure File Sync is a service that transforms Windows Server into a quick cache of your Azure file share. It bridges on-premises systems with Azure Files, enabling the following functionalities:

File Syncing:

  • Cloud Tiering: This feature automatically moves rarely accessed files to the cloud, freeing up local space.
  • Multi-site Sync: Azure File Sync can synchronize data across different geographical locations, keeping files updated and accessible everywhere.

Configuration Example:

# Import the Azure File Sync module Import-Module "StorageSync" # Register the server with Storage Sync Service $subscriptionId = "<SubscriptionId>" $resourceGroupName = "<ResourceGroupName>" $storageSyncServiceName = "<StorageSyncServiceName>" $registeredServer = Register-Server -SubscriptionId $subscriptionId -ResourceGroupName $resourceGroupName -StorageSyncServiceName $storageSyncServiceName

This code snippet outlines how to import the Azure File Sync module and register a server with Storage Sync Service, setting the stage for a seamless integration with Azure.

How AzCopy and Azure File Sync Work Together

While AzCopy and Azure File Sync might seem like distinct tools at first glance, they can be combined to achieve a more flexible and powerful file management system in Azure. Here’s how they complement each other:

1. Streamlined Data Transfers:

  • AzCopy handles bulk data transfers, making it perfect for initial data migration to Azure.
  • Azure File Sync takes over from there, ensuring that the data stays synchronized between Azure and on-premises systems.

2. Enhanced Flexibility:

  • Use AzCopy for specialized tasks, like moving data between various storage types.
  • Azure File Sync maintains the file consistency across different locations, offering a cloud-based centralized system.

3. Cost-Effective Solution:

  • AzCopy’s incremental copy feature, coupled with Azure File Sync’s cloud tiering, leads to efficient data management and can result in cost savings.

Integration Example:

Suppose you want to migrate a large amount of data to Azure File Share and then keep it in sync with on-premises servers. Here’s a possible workflow:

  1. Use AzCopy to Upload Data:
    azcopy copy 'C:\local\path' '' --recursive
  2. Set Up Azure File Sync for Continuous Synchronization:
    # Create a sync group and a cloud endpoint $syncGroupName = "MySyncGroup" New-SyncGroup -StorageSyncService $storageSyncService -Name $syncGroupName New-CloudEndpoint -StorageSyncService $storageSyncService -SyncGroupName $syncGroupName -StorageAccountResourceId $storageAccount.ResourceId -AzureFileShareName $fileShareName

Pros and Cons


  • Efficient Data Handling: AzCopy and Azure File Sync together offer a comprehensive solution for data migration and synchronization.
  • Scalability: Both tools can handle data sets of various sizes, providing scalability as your business grows.
  • Automation Capabilities: They allow for scheduled jobs and automation, streamlining the data management process.


  • Complexity: The combination may introduce complexity for those unfamiliar with the tools, requiring proper knowledge and implementation.
  • Potential Costs: While cost-effective in many scenarios, inappropriate usage can lead to unexpected charges, especially if not combined with proper monitoring and governance strategies.
