The goal is to move the data from existing file share locations to Azure. At this time, AzCopy is not a recommended tool for migration scenarios with Azure file shares as the target. That makes for an incomplete differential-copy feature set. An important difference in using AzCopy -sync is that deleted files on the source are not removed on the target. However, there are still gaps and there can easily be misunderstandings of functionality when comparing AzCopy flags to RoboCopy flags.Īn example: RoboCopy /MIR will mirror source to target - that means added, changed, and deleted files are considered. Check out the file fidelity section in the migration overview article to learn more about the importance of copying files at maximum possible fidelity.ĪzCopy, on the other hand, has only recently expanded to support file copy with some fidelity and added the first features needed to be considered as a migration tool.

RoboCopy supports many migration scenarios due to its rich set of features and the ability to copy files and folders in full fidelity. RoboCopy, as a trusted, Windows-based copy tool, has the home-turf advantage when it comes to copying files at full fidelity. AzCopy is a 'born-in-the-cloud' tool that can be used to move data as long as the target is in Azure storage. RoboCopy uses any version of the SMB protocol. Premium file shares (FileStorage), LRS/ZRSĪzCopy and RoboCopy are two fundamentally different file copy tools. Look through the table of migration guides to find the migration that best suits your needs. There are many different migration routes for different source and deployment combinations.

No caching files on-premises: Because the final goal is to use the Azure file shares directly in the cloud, there's no plan to use Azure File Sync.

Migration route: From source storage ⇒ Windows machine with RoboCopy ⇒ Azure file share.

Data sources: Any source supporting the SMB protocol, such as Network Attached Storage (NAS), Windows or Linux servers, another Azure file share, and many more.
