Azure AZCopy is a command-line utility provided by Microsoft Azure for copying data to and from Azure Blob Storage, Azure Files, and Azure Data Lake Storage. It is a powerful tool that allows you to transfer data to and from Azure storage services efficiently. Here are some key features and use cases for AZCopy:

1. Data Migration: AZCopy is commonly used for migrating data to Azure cloud storage from on-premises systems, other cloud providers, or within Azure itself. It supports various data sources and destinations.

2. Bulk Data Transfer: You can use AZCopy to perform bulk data transfers, making it suitable for scenarios where you need to move large amounts of data quickly and efficiently.

3. Parallel Transfers: AZCopy can perform multiple data transfers in parallel, which can significantly improve data transfer speed when dealing with large datasets.

4. Synchronization: It supports synchronization between a source and destination, ensuring that only the changed or new files are transferred, which is useful for maintaining data consistency.

5. Blob-to-Blob Copy: You can copy data between Azure Blob containers or even between different Azure Storage accounts.

6. Preservation of Metadata: AZCopy can preserve file and blob metadata, such as timestamps and permissions, during the transfer.

7. Resume Capability: It has built-in resiliency features, allowing you to resume interrupted transfers without starting from scratch.

8. Cross-Platform: AZCopy is available for Windows, Linux, and macOS, making it versatile and accessible across various environments.

9. Scripting and Automation: It can be incorporated into scripts and automation workflows, enabling scheduled or scripted data transfers.

Here is a basic example of how to use AZCopy to copy data from a local directory to an Azure Blob Storage container:

In this example:

• path/to/local/files is the local directory containing the data you want to copy.
• https://yourstorageaccount.blob.core.windows.net/containername is the destination Azure Blob Storage container.
• --recursive=true specifies that the copy operation should be recursive for directories.
