Restore Container

The Restore Container operation restores the contents and properties of a soft-deleted container to a specified container. The Restore Container operation is available on version 2019-12-12 and later.

Request

You can construct the Restore Container request by using a valid request, authorized by using shared key, account shared access signature authorization, or role-based access control.

Method	Request URI	HTTP version
PUT	https://myaccount.blob.core.windows.net/destinationcontainer?restype=container&comp=undelete	HTTP/1.1
PUT	https://myaccount.blob.core.windows.net/destinationcontainer?restype=container&comp=undelete&sv=validsastoken	HTTP/1.1

URI parameters

You can specify the following additional parameters on the request URI.

Parameter	Description
restype	Required. The restype parameter value must be container.
comp	Required. The comp parameter value must be undelete.
timeout	Optional. The timeout parameter is expressed in seconds. For more information, see Setting timeouts for Blob Storage operations.

Request headers

The following table describes required and optional request headers.

Request header	Description
Authorization	Required. Specifies the authorization scheme, account name, and signature. For more information, see Authorize requests to Azure Storage.
Date or x-ms-date	Required. Specifies the Coordinated Universal Time (UTC) for the request. For more information, see Authorize requests to Azure Storage.
x-ms-version	Required for all authorized requests. Specifies the version of the operation to use for this request. For this operation, the version must be 2018-03-28 or later. For more information, see Versioning for the Azure Storage services.
x-ms-client-request-id	Optional. Provides a client-generated, opaque value with a 1-kibibyte (KiB) character limit that's recorded in the logs when logging is configured. We highly recommend that you use this header to correlate client-side activities with requests that the server receives. For more information, see Monitor Azure Blob Storage.
x-ms-deleted-container-name	Required. You use this header to uniquely identify the soft-deleted container that should be restored.
x-ms-deleted-container-version	Required. You use this header to uniquely identify the soft-deleted container that should be restored. You can obtain this value from specifying the deleted value in the include query parameter of the List Containers operation. For more information, see List Containers.

Request body

None.

Response

The response includes an HTTP status code and a set of response headers.

Status code

A successful operation returns status code 201 (Created). For information about status codes, see Status and error codes.

Response headers

The response for this operation includes the following headers. The response can also include additional, standard HTTP headers. All standard headers conform to the HTTP/1.1 protocol specification.

Response header	Description
x-ms-request-id	Uniquely identifies the request that was made and can be used for troubleshooting the request. For more information, see Troubleshooting API operations.
x-ms-version	Version 2009-09-19 and later. Indicates the version of Azure Blob Storage used to run the request.
Date	A UTC date/time value that indicates the time at which the response was initiated. The service generates this value.
Content-Length	The length of the request body. For this operation, the content length is always zero.

Response body

None.

Authorization

Authorization is required when you're calling any data access operation in Azure Storage. You can authorize the Restore Container operation as described in the following sections.

Microsoft Entra ID

Azure Storage supports using Microsoft Entra ID to authorize requests to blob data. With Microsoft Entra ID, you can use Azure role-based access control (Azure RBAC) to grant permissions to a security principal. The security principal can be a user, group, application service principal, or Azure managed identity. The security principal is authenticated by Microsoft Entra ID to return an OAuth 2.0 token. The token can then be used to authorize a request against Blob Storage.

To learn more about authorization by using Microsoft Entra ID, see Authorize access to blobs using Microsoft Entra ID.

Permissions

The following RBAC actions are necessary for a Microsoft Entra user, group, or service principal to call the Restore Container operation, and the least privileged built-in Azure RBAC role that includes this action:

• Azure RBAC action: Microsoft.Storage/storageAccounts/blobServices/containers/write
• Least privileged built-in role: Storage Blob Data Contributor

To learn more about assigning roles by using Azure RBAC, see Assign an Azure role for access to blob data.

Shared access signatures

A shared access signature (SAS) provides secure delegated access to resources in a storage account. With a SAS, you have granular control over how a client can access data. You can specify what resource the client can access, what permissions they have to those resources, and how long the SAS is valid.

The Restore Container operation supports authorization using an account SAS.

When Shared Key access is disallowed for the storage account, an account SAS token will not be permitted on a request to Blob Storage. To learn more, see Understand how disallowing Shared Key affects SAS tokens.

Account SAS

An account SAS is secured with the storage account key. An account SAS delegates access to resources in one or more of the storage services. All of the operations available via a service or user delegation SAS are also available via an account SAS.

The following table indicates the signed resource type and signed permissions to specify when you're delegating access:

Operation	Signed service	Signed resource type	Signed permission
Restore Container	Blob (b)	Container (c)	Write (w)

To learn more about the account SAS, see Create an account SAS.

Shared key

The Restore Container operation supports Shared Key authorization. We don't recommend authorizing with account keys for most scenarios, because it's less secure.

We recommend disallowing Shared Key authorization for the storage account when possible. For more information, see Prevent authorization with Shared Key.

Remarks

• You can set the container delete retention policy on the account by using the Storage Resource Provider.
• The specified container must not exist at the time that the Restore Container operation is performed.
• If the specified container exists, the Restore Container operation will fail with a 409 (Conflict).
• If the soft-deleted container does not exist, has already been used as the source of a Restore Container operation, or has exceeded its retention days, the operation will fail with a 409 (Conflict).

Billing

Pricing requests can originate from clients that use Blob Storage APIs, either directly through the Blob Storage REST API, or from an Azure Storage client library. These requests accrue charges per transaction. The type of transaction affects how the account is charged. For example, read transactions accrue to a different billing category than write transactions. The following table shows the billing category for Restore Container requests based on the storage account type:

Operation	Storage account type	Billing category
Restore Container	Premium block blob Standard general-purpose v2 Standard general-purpose v1	List and Create Container operations

To learn about pricing for the specified billing category, see Azure Blob Storage Pricing.
