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.

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.

Important

Microsoft recommends using Microsoft Entra ID with managed identities to authorize requests to Azure Storage. Microsoft Entra ID provides superior security and ease of use compared to Shared Key authorization.

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, managed identity, or service principal to call the Restore Container operation, and the least privileged built-in Azure RBAC role that includes this action:

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

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
