Create a storage account
An Azure storage account contains all of your Azure Storage data objects: blobs, files, queues, and tables. The storage account provides a unique namespace for your Azure Storage data that is accessible from anywhere in the world over HTTP or HTTPS. For more information about Azure storage accounts, see Storage account overview.
In this how-to article, you learn to create a storage account using the Azure portal, Azure PowerShell, Azure CLI, or an Azure Resource Manager template.
If you don't have an Azure subscription, create a free account before you begin.
Next, sign in to Azure.

Create a storage account
A storage account is an Azure Resource Manager resource. Resource Manager is the deployment and management service for Azure. For more information, see Azure Resource Manager overview.
Every Resource Manager resource, including an Azure storage account, must belong to an Azure resource group. A resource group is a logical container for grouping your Azure services. When you create a storage account, you have the option to either create a new resource group, or use an existing resource group. This how-to shows how to create a new resource group.
To create an Azure storage account with the Azure portal, follow these steps:
From the left portal menu, select Storage accounts to display a list of your storage accounts. If the portal menu isn't visible, click the menu button to toggle it on.
On the Storage accounts page, select Create.
Options for your new storage account are organized into tabs in the Create a storage account page. The following sections describe each of the tabs and their options.
On the Basics tab, provide the essential information for your storage account. After you complete the Basics tab, you can choose to further customize your new storage account by setting options on the other tabs, or you can select Review + create to accept the default options and proceed to validate and create the account.
The following table describes the fields on the Basics tab.
|Section||Field||Required or optional||Description|
|Project details||Subscription||Required||Select the subscription for the new storage account.|
|Project details||Resource group||Required||Create a new resource group for this storage account, or select an existing one. For more information, see Resource groups.|
|Instance details||Storage account name||Required||Choose a unique name for your storage account. Storage account names must be between 3 and 24 characters in length and may contain numbers and lowercase letters only.|
|Instance details||Region||Required||Select the appropriate region for your storage account. For more information, see Regions and Availability Zones in Azure.
Not all regions are supported for all types of storage accounts or redundancy configurations. For more information, see Azure Storage redundancy.
The choice of region can have a billing impact. For more information, see Storage account billing.
|Instance details||Performance||Required||Select Standard performance for general-purpose v2 storage accounts (default). This type of account is recommended by Microsoft for most scenarios. For more information, see Types of storage accounts.
Select Premium for scenarios requiring low latency. After selecting Premium, select the type of premium storage account to create. The following types of premium storage accounts are available:
Microsoft recommends creating a general-purpose v2, premium block blob, or premium file share account for most scenarios. To select a legacy account type, use the link provided beneath Instance details. For more information about legacy account types, see Legacy storage account types.
|Instance details||Redundancy||Required||Select your desired redundancy configuration. Not all redundancy options are available for all types of storage accounts in all regions. For more information about redundancy configurations, see Azure Storage redundancy.
If you select a geo-redundant configuration (GRS or GZRS), your data is replicated to a data center in a different region. For read access to data in the secondary region, select Make read access to data available in the event of regional unavailability.
The following image shows a standard configuration of the basic properties for a new storage account.
On the Advanced tab, you can configure additional options and modify default settings for your new storage account. Some of these options can also be configured after the storage account is created, while others must be configured at the time of creation.
The following table describes the fields on the Advanced tab.
|Section||Field||Required or optional||Description|
|Security||Require secure transfer for REST API operations||Optional||Require secure transfer to ensure that incoming requests to this storage account are made only via HTTPS (default). Recommended for optimal security. For more information, see Require secure transfer to ensure secure connections.|
|Security||Allow enabling public access on containers||Optional||When enabled, this setting allows a user with the appropriate permissions to enable anonymous public access to a container in the storage account (default). Disabling this setting prevents all anonymous public access to the storage account. For more information, see Prevent anonymous public read access to containers and blobs.
Enabling blob public access does not make blob data available for public access unless the user takes the additional step to explicitly configure the container's public access setting.
|Security||Enable storage account key access||Optional||When enabled, this setting allows clients to authorize requests to the storage account using either the account access keys or an Azure Active Directory (Azure AD) account (default). Disabling this setting prevents authorization with the account access keys. For more information, see Prevent Shared Key authorization for an Azure Storage account.|
|Security||Default to Azure Active Directory authorization in the Azure portal||Optional||When enabled, the Azure portal authorizes data operations with the user's Azure AD credentials by default. If the user does not have the appropriate permissions assigned via Azure role-based access control (Azure RBAC) to perform data operations, then the portal will use the account access keys for data access instead. The user can also choose to switch to using the account access keys. For more information, see Default to Azure AD authorization in the Azure portal.|
|Security||Minimum TLS version||Required||Select the minimum version of Transport Layer Security (TLS) for incoming requests to the storage account. The default value is TLS version 1.2. When set to the default value, incoming requests made using TLS 1.0 or TLS 1.1 are rejected. For more information, see Enforce a minimum required version of Transport Layer Security (TLS) for requests to a storage account.|
|Security||Permitted scope for copy operations (preview)||Required||Select the scope of storage accounts from which data can be copied to the new account. The default value is
For more information, see Restrict the source of copy operations to a storage account.

To register for the preview, see About the preview.|
|Network routing||Routing preference||Required||The network routing preference specifies how network traffic is routed to the public endpoint of your storage account from clients over the internet. By default, a new storage account uses Microsoft network routing. You can also choose to route network traffic through the POP closest to the storage account, which may lower networking costs. For more information, see Network routing preference for Azure Storage.|
The following image shows a standard configuration of the networking properties for a new storage account.
Data protection tab
On the Data protection tab, you can configure data protection options for blob data in your new storage account. These options can also be configured after the storage account is created. For an overview of data protection options in Azure Storage, see Data protection overview.
The following table describes the fields on the Data protection tab.
|Section||Field||Required or optional||Description|
|Recovery||Enable point-in-time restore for containers||Optional||Point-in-time restore provides protection against accidental deletion or corruption by enabling you to restore block blob data to an earlier state. For more information, see Point-in-time restore for block blobs.
Enabling point-in-time restore also enables blob versioning, blob soft delete, and blob change feed. These prerequisite features may have a cost impact. For more information, see Pricing and billing for point-in-time restore.
|Recovery||Enable soft delete for blobs||Optional||Blob soft delete protects an individual blob, snapshot, or version from accidental deletes or overwrites by maintaining the deleted data in the system for a specified retention period. During the retention period, you can restore a soft-deleted object to its state at the time it was deleted. For more information, see Soft delete for blobs.
Microsoft recommends enabling blob soft delete for your storage accounts and setting a minimum retention period of seven days.
|Recovery||Enable soft delete for containers||Optional||Container soft delete protects a container and its contents from accidental deletes by maintaining the deleted data in the system for a specified retention period. During the retention period, you can restore a soft-deleted container to its state at the time it was deleted. For more information, see Soft delete for containers.
Microsoft recommends enabling container soft delete for your storage accounts and setting a minimum retention period of seven days.
|Recovery||Enable soft delete for file shares||Optional||Soft delete for file shares protects a file share and its contents from accidental deletes by maintaining the deleted data in the system for a specified retention period. During the retention period, you can restore a soft-deleted file share to its state at the time it was deleted. For more information, see Prevent accidental deletion of Azure file shares.
Microsoft recommends enabling soft delete for file shares for Azure Files workloads and setting a minimum retention period of seven days.
|Tracking||Enable versioning for blobs||Optional||Blob versioning automatically saves the state of a blob in a previous version when the blob is overwritten. For more information, see Blob versioning.
Microsoft recommends enabling blob versioning for optimal data protection for the storage account.
|Tracking||Enable blob change feed||Optional||The blob change feed provides transaction logs of all changes to all blobs in your storage account, as well as to their metadata. For more information, see Change feed support in Azure Blob Storage.|
|Access control||Enable version-level immutability support||Optional||Enable support for immutability policies that are scoped to the blob version. If this option is selected, then after you create the storage account, you can configure a default time-based retention policy for the account or for the container, which blob versions within the account or container will inherit by default. For more information, see Enable version-level immutability support on a storage account.|
The following image shows a standard configuration of the data protection properties for a new storage account.
On the Encryption tab, you can configure options that relate to how your data is encrypted when it is persisted to the cloud. Some of these options can be configured only when you create the storage account.
