Ivan Yang Ivan Yang Actually that's not correct.An Azure storage account contains all of your Azure Storage data objects: blobs, files, queues, tables, and disks.

Data in your Azure storage account is durable and highly available, secure, and massively scalable. To learn how to create an Azure storage account, see Create a storage account. Azure Storage offers several types of storage accounts.

Each type supports different features and has its own pricing model. Consider these differences before you create a storage account to determine the type of account that is best for your applications. The types of storage accounts are:. General-purpose v2 storage accounts support the latest Azure Storage features and incorporate all of the functionality of general-purpose v1 and Blob storage accounts.

General-purpose v2 accounts deliver the lowest per-gigabyte capacity prices for Azure Storage, as well as industry-competitive transaction prices. General-purpose v2 storage accounts support these Azure Storage services:.

Microsoft recommends using a general-purpose v2 storage account for most scenarios. You can easily upgrade a general-purpose v1 or Blob storage account to a general-purpose v2 account with no downtime and without the need to copy data. For more information on upgrading to a general-purpose v2 account, see Upgrade to a general-purpose v2 storage account. General-purpose v2 storage accounts offer multiple access tiers for storing data based on your usage patterns.

For more information, see Access tiers for block blob data. General-purpose v1 storage accounts provide access to all Azure Storage services, but may not have the latest features or the lowest per gigabyte pricing.

General-purpose v1 storage accounts support these Azure Storage services:.

Storage account overview

You should use general-purpose v2 accounts in most cases. You can use general-purpose v1 accounts for these scenarios:. Your applications require the Azure classic deployment model. General-purpose v2 accounts and Blob storage accounts support only the Azure Resource Manager deployment model.

Your applications are transaction-intensive or use significant geo-replication bandwidth, but don't require large capacity. In this case, general-purpose v1 may be the most economical choice.

You can't upgrade your application.This API is available starting in version The source for a Copy Blob From URL operation can be any committed block blob in any Azure storage account which is either public or authorized with a shared access signature.

HTTPS is recommended. Replace myaccount with the name of your storage account, mycontainer with the name of your container, and myblob with the name of your destination blob. When making a request against the emulated storage service, specify the emulator hostname and Blob service port as For information about status codes, see Status and Error Codes. The response for this operation includes the following headers.

The response may also include additional standard HTTP headers. This operation can be called by the account owner and by anyone with a Shared Access Signature that has permission to write to this blob or its container.

Access to the source blob or file is authorized separately, as described in the details for the request header x-ms-copy-source. If a request specifies tags with the x-ms-tags request header, the caller must meet the authorization requirements of the Set Blob Tags operation. The Copy Blob From URL operation always copies the entire source blob; copying a range of bytes or set of blocks is not supported. When copying from a block blob, all committed blocks and their block IDs are copied.

Uncommitted blocks are not copied. At the end of the copy operation, the destination blob will have the same committed block count as the source. When a block blob is copied, the following system properties are copied to the destination blob with the same values:.

The source blob's committed block list is also copied to the destination blob. Any uncommitted blocks are not copied. The destination blob is always the same size as the source blob, so the value of the Content-Length header for the destination blob matches that for the source blob.

If tags for the destination blob are provided in the x-ms-tags header, they must be query-string encoded. Tag keys and values must conform to the naming and length requirements as specified in Set Blob Tags.

Further, the x-ms-tags header may contain up to 2kb of tags. If more tags are required, use the Set Blob Tags operation. If tags are not provided in the x-ms-tags header, then they are not copied from the source blob.

The Copy Blob From URL operation only reads from the source blob so the lease state of the source blob does not matter. The destination account of a Copy Blob From URL operation is charged for one transaction to initiate the copy, and also incurs one transaction for each request to the source of the copy operation.

The source account also incurs transaction costs. In addition, if the source and destination accounts reside in different regions e. Egress between accounts within the same region is free.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Blob storage is optimized for storing massive amounts of unstructured data. The features described in this article are now available to accounts that have a hierarchical namespace.

This section walks you through preparing a project to work with the Azure Blob storage client library v12 for. In a console window such as cmd, PowerShell, or Bashuse the dotnet new command to create a new console app with the name BlobQuickstartV This command creates a simple "Hello World" C project with a single source file: Program.

In side the BlobQuickstartV12 directory, create another directory called data. This is where the blob data files will be created and stored. While still in the application directory, install the Azure Blob storage client library for. NET package by using the dotnet add package command. When the sample application makes a request to Azure Storage, it must be authorized.

To authorize a request, add your storage account credentials to the application as a connection string. View your storage account credentials by following these steps:. In the Settings section of the storage account overview, select Access keys.

Here, you can view your account access keys and the complete connection string for each key. Find the Connection string value under key1and select the Copy button to copy the connection string.

You will add the connection string value to an environment variable in the next step. After you have copied your connection string, write it to a new environment variable on the local machine running the application. To set the environment variable, open a console window, and follow the instructions for your operating system. After you add the environment variable in Windows, you must start a new instance of the command window. After you add the environment variable, restart any running programs that will need to read the environment variable.

For example, restart your development environment or editor before continuing. Azure Blob storage is optimized for storing massive amounts of unstructured data.

When making a request against the emulated storage service, specify the emulator hostname and Blob service port as Beginning with versionthe following headers may be specified on the request to encrypt a blob with a customer-provided key.

Encryption with a customer-provided key and the corresponding set of headers is optional. For information about status codes, see Status and Error Codes. The response for this operation includes the following headers. The response may also include additional standard HTTP headers. This operation can be called by the account owner and by anyone with a Shared Access Signature that has permission to write to this blob or its container. A block blob can include a maximum of 50, blocks.

Each block can be a different size. To upload larger blocks up to MiBsee Put Block. A blob can have a maximum ofuncommitted blocks at any given time. After you have uploaded a set of blocks, you can create or update the blob on the server from this set by calling the Put Block List operation.

Each block in the set is identified by a block ID that is unique within that blob. Block IDs are scoped to a particular blob, so different blobs can have blocks with same IDs. If you call Put Block From URL on a blob that does not yet exist, a new block blob is created with a content length of 0. The block or blocks that you uploaded are not committed until you call Put Block List on the new blob.

A blob created this way is maintained on the server for a week; if you have not added more blocks or committed blocks to the blob within that time period, then the blob is garbage collected. Before Put Block List is called to commit the new or updated blob, any calls to Get Blob return the blob contents without the inclusion of the uncommitted block.

If you upload a block that has the same block ID as another block that has not yet been committed, the last uploaded block with that ID will be committed on the next successful Put Block List operation. After Put Block List is called, all uncommitted blocks specified in the block list are committed as part of the new blob.

Any uncommitted blocks that were not specified in the block list for the blob will be garbage collected and removed from the Blob service. If Put Blob is called on the blob, any uncommitted blocks will be garbage collected. If the blob has an active lease, the client must specify a valid lease ID on the request in order to write a block to the blob.
