Getting Started with AZCopy
To begin using AZCopy, you'll need to download and install the utility. Once installed, you can connect to your Azure storage account and start transferring data using simple commands1. For example, to upload a file to Azure Blob Storage, you can use the following command:
Basic Commands with Syntax
Download AZCopy
First, you'll need to download AZCopy and install it. Once installed, you can start using the commands.
Copy a File to Azure Blob Storage
To copy a file from your local machine to an Azure Blob Storage container, use the following command:
bash
azcopy copy 'C:\path\to\your\file.txt' 'https://<your-storage-account-name>.blob.core.windows.net/<container-name>/<blob-name>'
Copy a Directory to Azure Blob Storage
If you want to copy an entire directory, you can use this command:
bash
azcopy copy 'C:\path\to\your\directory' 'https://<your-storage-account-name>.blob.core.windows.net/<container-name>?sastoken'
Copy Files Between Azure Storage Accounts
You can also copy data between two Azure Storage accounts. Here’s how to copy a blob from one storage account to another:
bash
azcopy copy 'https://<source-storage-account>.blob.core.windows.net/<source-container>/<blob-name>?sastoken' 'https://<destination-storage-account>.blob.core.windows.net/<destination-container>/<blob-name>?sastoken'
List Files in a Container
To list all the files in a container, you can use the following command:
bash
azcopy list 'https://<your-storage-account-name>.blob.core.windows.net/<container-name>?sastoken'
Remove Files from a Container
If you need to delete a file from an Azure Blob Storage container, you can use:
bash
azcopy remove 'https://<your-storage-account-name>.blob.core.windows.net/<container-name>/<blob-name>?sastoken'
Practical Example
Let’s say you have a file called data.csv on your local machine in the C:\data\ directory, and you want to upload it to a container named mycontainer in a storage account called mystorageaccount. You would use the following command:
bash
azcopy copy 'C:\data\data.csv' 'https://mystorageaccount.blob.core.windows.net/mycontainer/data.csv'
SAS Tokens
Many of these commands include a Shared Access Signature (SAS) token, which provides secure delegated access to your storage resources. You’ll need to generate a SAS token for your storage account to use these commands securely.
Conclusion
AZCopy is a versatile and powerful tool for managing your data transfers to and from Azure Storage. Its command-line interface allows for efficient and automated data operations, making it invaluable for developers and IT professionals.
