How To Manage Storage Accounts

How to: Manage storage account replication

You have three options for replicating your storage account:

  • Geo-redundant replication. Geo-redundant replication is enabled for your storage account by default. With geo-redundant replication, your data is replicated to a secondary geographic location to enable failover to that location in case of a major disaster in the primary location. The secondary location is in the same region, but is hundreds of miles from the primary location.

  • Read access geo-redundant replication. Read access geo-redundant replication replicates your data to a secondary geographic location, and also provides read access to your data in the secondary location. Read-access geo-redundant replication allows you to access your data from either the primary or the secondary location, in the event that one location becomes unavailable.

  • Locally redundant replication. With locally redundant replication, your storage account data is replicated three times within the same data center. Locally redundant replication is offered at discounted rates.

    Be aware that if you specify locally redundant replication for your storage account, and you later decide to enable geo-redundant replication, you will incur a one-time data cost to replicate your existing data to the secondary location.

  • Read access geo-redundant replication (preview only). Read access geo-redundant replication replicates your data to a secondary geographic location, and also provides read access to your data in the secondary location. Read-access geo-redundant replication allows you to access your data from either the primary or the secondary location, in the event that one location becomes unavailable.

For pricing information for storage account replication, see Storage Pricing Details.

To specify replication settings for a storage account

  1. In the Azure Management Portal, click Storage, and then click the name of your storage account to display the dashboard.

  2. Click Configure.

  3. In the Replication, field, select the type of replication you want for your storage account.

  4. Click Save, and confirm your choice if prompted.

How to: View, copy, and regenerate storage access keys

When you create a storage account, Azure generates two 512-bit storage access keys, which are used for authentication when the storage account is accessed. By providing two storage access keys, Azure enables you to regenerate the keys with no interruption to your storage service or access to that service.

In the Management Portal, use Manage Keys on the dashboard or the Storage page to view, copy, and regenerate the storage access keys that are used to access the Blob, Table, and Queue services.

Copy a storage access key

You can use Manage Keys to copy a storage access key to use in a connection string. The connection string requires the storage account name and a key to use in authentication. For information about configuring connection strings to access Azure storage services, see Configuring Connection Strings.

  1. In the Management Portal, click Storage, and then click the name of the storage account to open the dashboard.

  2. Click Manage Keys.

    Manage Access Keys opens.

    Managekeys

  3. To copy a storage access key, select the key text. Then right-click, and click Copy.

Regenerate storage access keys

You should change the access keys to your storage account periodically to help keep your storage connections more secure. Two access keys are assigned to enable you to maintain connections to the storage account using one access key while you regenerate the other access key.

Warning

Regenerating your access keys affects virtual machines, media services, and any applications that are dependent on the storage account.

**Virtual machines** - If your storage account contains any virtual machines that are running, you will have to redeploy all virtual machines after you regenerate the access keys. To avoid redeployment, shut down the virtual machines before you regenerate the access keys. **Media services** - If you have media services dependent on your storage account, you must re-sync the access keys with your media service after you regenerate the keys. **Applications** - If you have web applications or cloud services using the storage account, you will lose the connections if you regenerate keys, unless you roll your keys. Here is the process: 1. Update the connection strings in your application code to reference the secondary access key of the storage account. 2. Regenerate the primary access key for your storage account. In the [Management Portal](http://manage.windowsazure.com), from the dashboard or the **Configure** page, click **Manage Keys**. Click **Regenerate** under the primary access key, and then click **Yes** to confirm you want to generate a new key. 3. Update the connection strings in your code to reference the new primary access key. 4. Regenerate the secondary access key.

How to: Delete a storage account

To remove a storage account that you are no longer using, use **Delete** on the dashboard or the **Configure** page. **Delete** deletes the entire storage account, including all of the blobs, tables, and queues in the account.
Warning

There's no way to restore the content from a deleted storage account. Make sure you back up anything you want to save before you delete the account.

If your storage account contains any VHD files or disks for an Azure virtual machine, then you must delete any images and disks that are using those VHD files before you can delete the storage account. First, stop the virtual machine if it is running, and then delete it. To delete disks, navigate to the Disks tab and delete any disks contained in the storage account. To delete images, navigate to the Images tab and delete any images stored in the account.

  1. In the Management Portal, click Storage.

  2. Click anywhere in the storage account entry except the name, and then click Delete.

    -Or-

    Click the name of the storage account to open the dashboard, and then click Delete.

  3. Click Yes to confirm you want to delete the storage account.
