Azure storage services
📘Microsoft Certified: Azure Fundamentals (AZ-900)
Azure provides several tools to move, manage, and sync files in and out of Azure Storage. The main tools are:
- AzCopy
- Azure Storage Explorer
- Azure File Sync
Let’s go through each one.
1. AzCopy
What it is:
- AzCopy is a command-line tool that helps you upload, download, or copy files and blobs to and from Azure Storage.
- It is fast and efficient, especially for moving large amounts of data.
Key points for the exam:
- AzCopy works with Blob Storage, File Storage, and Table Storage.
- It supports resuming interrupted transfers, which is useful for large files.
- You can copy files between storage accounts, or even from on-premises servers to Azure.
How it’s used in IT:
- Example: A company wants to migrate backup files from a local server to Azure Blob Storage. They can write an AzCopy command to upload thousands of files in a few minutes.
Exam tip:
- Know that AzCopy is command-line based, used for large-scale, automated file transfers, and supports resuming interrupted transfers.
2. Azure Storage Explorer
What it is:
- Azure Storage Explorer is a graphical tool (GUI) that helps you manage files in Azure Storage.
- You don’t need to use commands—just click and drag to upload or download files.
Key points for the exam:
- Supports Blob Storage, File Storage, Queue Storage, and Table Storage.
- Lets you browse storage accounts, containers, and file shares.
- Works on Windows, macOS, and Linux.
- Ideal for manual file transfers, small datasets, or visual management.
How it’s used in IT:
- Example: A developer wants to check files in a Blob Storage container or upload a few new documents. They can use Azure Storage Explorer’s GUI to do it quickly.
Exam tip:
- Remember: Azure Storage Explorer = GUI tool for managing and transferring files, especially when you don’t need scripts or automation.
3. Azure File Sync
What it is:
- Azure File Sync is a service that keeps on-premises file servers and Azure File shares in sync.
- It’s more than just file transfer—it mirrors files in real-time between your local server and Azure.
Key points for the exam:
- You install an agent on your on-premises server.
- Changes on the server are automatically synced to Azure.
- Supports tiering, which means rarely accessed files can move to Azure to save local storage.
- Useful for disaster recovery and hybrid environments.
How it’s used in IT:
- Example: A company has a local file server that teams access daily. Using Azure File Sync, all files are automatically synced to the cloud so remote employees can also access them without touching the local server.
Exam tip:
- Remember: Azure File Sync = automatic, real-time sync between on-premises servers and Azure File shares.
- Unlike AzCopy, it’s not for one-time transfers—it’s continuous synchronization.
Quick Comparison Table for the Exam
| Tool | Type | Best Use Case | Key Feature |
|---|---|---|---|
| AzCopy | Command-line | Large-scale, automated file transfers | Fast, supports resuming interrupted transfers |
| Azure Storage Explorer | GUI | Small datasets, manual management | Click-and-drag file management |
| Azure File Sync | Service | Sync on-premises servers with Azure File Storage | Real-time sync, cloud tiering, disaster recovery |
Summary for Exam
- AzCopy: CLI tool, fast for large-scale transfers, resumes broken transfers.
- Azure Storage Explorer: GUI tool, easy manual file management.
- Azure File Sync: Continuous sync service between local servers and Azure, supports tiering.
Key Exam Tip:
- The exam may ask:
- “Which tool is best for automated bulk file uploads?” → AzCopy
- “Which tool allows you to visually manage files in Azure Storage?” → Storage Explorer
- “Which tool keeps on-premises files in sync with Azure?” → Azure File Sync
