Azure Archive Storage
If you’re looking for a cost-effective way to store your rarely accessed data, Azure Storage Archive might be the perfect solution for you. This cloud-based storage service offered by Microsoft Azure provides an affordable and secure option for archiving data that is not frequently used, yet still requires retention for compliance reasons.
In this article, we’ll dive deep into Azure Storage Archive, discussing its features, benefits, and how it compares to other Azure storage options. We’ll also look at how to create an Azure Storage Archive, how to access and manage the archived data, and the costs associated with using this service.
How Azure Storage Archive Works
Azure Archive Storage uses a tiered storage architecture where data is automatically moved to a lower cost tier based on its access patterns. When you store data in Azure Archive Storage, it’s initially stored in a hot or cool storage tier for a specific period before it’s moved to the archive tier. This helps to optimize the cost of storage, as data that’s accessed frequently remains in the hot or cool tier, while less frequently accessed data is moved to the archive tier.
To access data stored in Azure Archive Storage, you need to initiate a retrieval request. The retrieval process may take several hours, depending on the amount of data you’re retrieving and the retrieval option you choose. Azure Archive Storage provides two retrieval options: standard and expedited. Standard retrieval is the default option and takes several hours to complete, while expedited retrieval takes minutes but is more expensive.
Benefits of Azure Storage Archive
Azure Storage Archive offers several benefits that make it an attractive option for organizations that need to retain large amounts of data for long periods of time. Some of the key benefits include:
Cost-effective:
One of the main benefits of using Azure Archive Storage is its cost-effectiveness. It’s a low-cost storage option compared to other storage tiers, making it ideal for storing rarely accessed data that doesn’t need to be immediately available. You can save up to 80% on storage costs compared to other tiers, which can be significant if you’re storing large amounts of data.
Security:
Azure Archive Storage provides several security features to protect your data. It uses server-side encryption to encrypt your data at rest, and SSL/TLS to encrypt data in transit. You can also configure network security groups to restrict access to your data, and use role-based access control (RBAC) to control who can access your data.
Compliant:
Azure Storage Archive helps organizations meet compliance requirements by providing a read-only storage option for archived data that cannot be modified.
Scalablility:
Azure Archive Storage is highly scalable, allowing you to store petabytes of data without worrying about capacity constraints. It’s built on Azure’s global infrastructure, which provides high availability and reliability. You can easily scale up or down based on your storage needs, and pay only for what you use.
Accessible:
Archived data can be accessed through the Azure portal, REST API, Azure Storage Explorer or Cloud Storage Manager, making it easy for organizations to retrieve data when needed.
Use Cases for Azure Storage Archive
Azure Storage Archive is an ideal solution for organizations that need to store large amounts of data for long periods of time, but do not need to access that data frequently. Some common use cases include:
Azure Archive Storage is an ideal solution for meeting regulatory compliance requirements. Many regulations require businesses to retain data for a specified period, and Azure Archive Storage makes it easy to store data for long periods without incurring high costs. You can also set retention policies to ensure that data is not deleted before the required retention period.
Azure Archive Storage can be used for long-term backup and disaster recovery purposes. You can store backups of your data in the archive tier, and retrieve them when needed. In case of a disaster, you can restore your data from the archive tier, which provides an additional layer of protection for your data.
Historical Data:
Organizations that need to retain historical data, such as financial records or customer information, can use Azure Storage Archive to store this data cost-effectively.
Media and Entertainment:
Digital media assets such as photos, videos, and audio files are often stored for long periods and rarely accessed. Azure Archive Storage provides a cost-effective way to store and manage these assets, allowing you to keep them for years while keeping them accessible when needed.

How to get started with Azure Archive Storage
To get started with Azure Archive Storage, you need to create a storage account and enable the archive tier. You can then upload your data to the archive tier using Azure Storage Explorer, Azure portal, or Azure CLI. Once your data is uploaded, you can retrieve it when needed by initiating a retrieval request.
To move Azure blobs to archive storage, you can follow these steps:
- Log in to your Azure portal and navigate to your Storage account where the blobs are stored.
- Select the container that contains the blobs you want to move to archive storage.
- Click on the “Blob” tab and select the blobs you want to move.
- Click on the “Upload” button and choose “Upload as Archive” option from the dropdown list.
- Specify the destination container for your archive blobs and click “Upload” to start the transfer.
- Wait for the transfer to complete. This process may take some time depending on the size of your blobs and your internet speed.
- Once the transfer is complete, your blobs will now be stored in archive storage.
Note that when blobs are moved to archive storage, they become read-only, meaning you cannot modify or delete them until they are moved back to hot or cool storage. Also, archive storage has a lower access cost compared to hot or cool storage, but a higher data retrieval cost.
Deep Scan your Azure Storage
Open Cloud Storage Manager and perform a Deep Scan of your environment.
The deep scan interogates every subscription, storage account, container and of course blob file for information.
This information besides the size and metadata will also include what storage tier your blobs reside in.
How to move blobs to archive
Now that Cloud Storage Manager has completed a Deep Scan of your environment, browse through the Subscription, then storage account and choose the Blob View TAB.
This will show you all the blobs within the selected Storage Account or Container.
To move the blobs to the archive tier, highlight the blobs you need and then right click. (you can highlight multiple ones by holding down the Control or Shift keys)
Select the blobs to archive
Now that Cloud Storage Manager has completed a Deep Scan of your environment, browse through the Subscription, then storage account and choose the Blob View TAB.
This will show you all the blobs within the selected Storage Account or Container.
To move the blobs to the archive tier, highlight the blobs you need and then right click. (you can highlight multiple ones by holding down the Control or Shift keys)
Move blobs to archive
You can now choose what storage tier you want those blobs to go to.
Since we are talking about the Archive Tier, I chose that and clicked on OK.
Blobs are now migrating to Azure Archive Storage
Within the ACTIVITY TAB of Cloud Storage Manager, we can see that those blobs are now moving down to the Archive Storage Tier.
See the Tiering of your Azure Blobs
Now I went back to the Blob View of the selected storage account, and you can see that the blobs that I asked Cloud Storage Manager to move to Archive are now indeed in the Archive Storage Tier.
Accessing and Managing Archived Data
Accessing and managing archived data is also straightforward, with several options available depending on your needs. You can access archived data through the Azure portal, REST API, Azure Storage Explorer or Cloud Storage Manager, and can restore data to the cool or hot tier for faster access if needed. You can also set up lifecycle policies to automatically move data between tiers based on your organization’s retention policies.

As a cloud administrator or developer, you may have accidentally deleted a storage account containing critical data. Losing important information can be a frustrating and costly experience. Fortunately, Azure provides several ways to recover a deleted storage account. In this article, we will discuss the steps involved in recovering a deleted storage account in Azure.
Azure Storage Accounts provide a reliable and scalable solution for storing unstructured data in the cloud. A storage account is a logical container for data objects such as blobs, files, tables, and queues. Accidental deletion of a storage account can result in the loss of critical data, which can have severe consequences for businesses. In this article, we will explore the steps involved in recovering a deleted storage account in Azure.
Understanding Azure Storage Accounts
Azure Storage Accounts are the basic building blocks for storing data in Azure. There are four types of storage accounts in Azure: General-purpose v2 storage accounts, General-purpose v1 storage accounts, Blob storage accounts, and Premium performance v2 storage accounts. Each storage account has a unique name that is used to access its data objects. Azure storage accounts provide several features, such as data replication, scalability, and security.
- General-purpose v2 storage accounts
- General-purpose v1 storage accounts
- Blob storage accounts
- Premium performance v2 storage accounts
Each storage account has a unique name that is used to access its data objects. Azure storage accounts provide several features, such as data replication, scalability, and security.
Reasons for Deleting a Storage Account
There can be various reasons for deleting a storage account in Azure, such as:
- The storage account is no longer required.
- The storage account is not compliant with organizational policies.

Best Practices to Avoid Accidental Deletion of Storage Accounts
Accidental deletion of a storage account can be avoided by following these best practices:
- Use role-based access control (RBAC) to restrict access to storage accounts.
- Use resource locks to prevent accidental deletion of storage accounts.
- Use Azure Backup to create regular backups of storage accounts.
- Use Azure Resource Manager templates to deploy storage accounts with predefined configurations.
Azure Storage Account Deletion RABC
To prevent accidental deletion of storage accounts using Role Based Access Controls, here are some guiding principles;
Prevention Method |
Description |
Example |
Role-based access control (RBAC)
|
Assign appropriate access roles to users and groups to limit their permissions on the storage account. |
Assign a user with the “Contributor” role instead of “Owner” to restrict their ability to delete the storage account. |
Resource locks
|
Use locks to block users from deleting a resource, even if they have the necessary permissions. |
Apply a “CanNotDelete” lock on the storage account to prevent accidental deletion. |
It’s important to note that RBAC can be used not only to prevent accidental deletion, but also to restrict other types of operations on the storage account, such as reading or modifying data. Resource locks are specifically designed to prevent deletion and can be applied at the resource group or resource level.
Here’s a table that of the different RBAC roles and their permissions in Azure:
