Moving files between different storage mediums is a critical task in cloud computing, and Microsoft Azure provides multiple methods to perform this task. Three of these methods include AzCopy, Azure Storage Explorer, and Azure File Sync. Each of these options has its own unique features and is designed for specific scenarios. By understanding these three methods, you can determine which is most suitable for your needs.
AzCopy
AzCopy is a command-line utility designed for high-performance copying of data to or from Azure Blob storage and File Storage, and between Azure Storage accounts. Due to its high-speed performance, AzCopy is often preferred for transferring large amounts of data or for automating transfer tasks.
To use AzCopy, it must be installed and configured through Azure CLI (Command-Line Interface). Here’s a basic example of using AzCopy to upload a local file to a Blob storage:
azcopy copy ‘C:\local\path\myfile.txt’ ‘https://mystorageaccount.blob.core.windows.net/mycontainer/myfile.txt’
Replace ‘C:\local\path\myfile.txt” with the path and filename of the file you want to upload and replace the link with the URL to your Azure Blob container + file name.
Azure Storage Explorer
Azure Storage Explorer offers a GUI-based approach to manipulating and moving files within Azure. You may connect to and manage multiple subscriptions and resources across Azure, Azure Stack, and the local environment.
The Storage Explorer allows you to perform all basic tasks like uploading, downloading, and deleting Blob files, managing and filtering your Blob containers, and much more.
To use it, simply download and install the tool. The user can then navigate through their storage accounts, opening containers, and selecting files just like in a normal file system.
Azure File Sync
Azure File Sync allows you to centralize your file services in Azure while maintaining the compatibility and accessibility of an on-premises file server. Azure File Sync provides rapid access to the files you’re using by caching them on local servers, effectively enabling a hybrid storage solution.
With Azure File Sync, changes made to the files on the local file server will be synced to your Azure file share. If changes are made to the files in the Azure file share, these changes will also be synced back down to your local file servers.
To implement Azure File Sync, you would need to provision a Storage Sync Service, install the Azure File Sync agent on a Windows Server, create a sync group, and then register your Windows Server with that sync group.
Comparison

In conclusion, the method you choose for transferring files in Azure will depend on your specific needs. AzCopy is ideal for high-performance data transfer, Azure Storage Explorer provides GUI capabilities for managing storage data, and Azure File Sync allows syncing between local and cloud systems. Understanding these tools and their functions will allow you to proficiently manage your data in Azure.
