If you place multiple file shares in a single storage account, you're creating a shared pool of IOPS and throughput for these shares.Īs a general rule, you can pool multiple Azure file shares into the same storage account if you have archival shares or you expect low day-to-day activity in them. For standard file shares, that arrangement makes the storage account a scale target for performance numbers like IOPS and throughput. Remember that an Azure file share is deployed in the cloud in an Azure storage account. In this phase, you'll provision the Azure storage accounts and the SMB Azure file shares within them. If you are returning to this article, use the navigation on the right side to jump to the migration phase where you left off. The following sections describe the phases of the migration process in detail. Once it's time for the actual data copy, you'll need to consider repeated, differential RoboCopy runs to minimize downtime, and finally, cut-over your users to the newly created Azure file shares. Next, you'll configure networking, consider a DFS Namespace deployment (DFS-N), or update your existing one. First, you'll need to deploy Azure storage accounts and file shares. The migration process consists of several phases. The latter requires keeping downtime to a minimum, so that it can fit into or only slightly exceed regular maintenance windows. This migration needs to be done in a way that guarantees the integrity of the production data and availability during the migration. In Azure, you'll store your data in native Azure file shares you can use without a need for a Windows Server. 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.
