sql azure 语法_如何将SQL Server数据库备份到Microsoft Azure

sql azure 语法

In the last chapter, we explained how to create a Microsoft Azure Account and how to have a Microsoft Azure Portal.

在上一章中，我们说明了如何创建Microsoft Azure帐户以及如何具有Microsoft Azure门户。

This time, we will show how to backup our SQL Server Databases to a Microsoft Azure. We are assuming that you already have an Azure account.

这次，我们将展示如何将SQL Server数据库备份到Microsoft Azure。我们假设您已经有一个Azure帐户。

介绍 ( Introduction )

Microsoft Azure stores your information with redundancy on the web. It is a safe and secure environment and simplifies your administrative tasks.

Microsoft Azure将您的信息以冗余方式存储在Web上。这是一个安全的环境，可简化您的管理任务。

入门 ( Getting Started )

There are two main steps to backup your database in Microsoft Azure:

在Microsoft Azure中备份数据库有两个主要步骤：

Create a Storage with a container in the Microsoft Azure portal.在Microsoft Azure门户中使用容器创建存储。
Backup your local Database to that container (you will need a credential to connect to the Storage).将本地数据库备份到该容器（您需要凭据才能连接到存储）。

在Microsoft Azure中创建存储和容器 ( Create a Storage and a Container in Microsoft Azure )

The first step to backup in Azure is to create a storage.

在Azure中进行备份的第一步是创建一个存储。

First, sign in to the Microsoft Azure Portal:

首先，登录到Microsoft Azure门户：

https://manage.windowsazure.com

Click on the Storage link to create a new storage.

单击存储链接以创建新的存储。

East US 2美国东部2
Central US美国中部
South Central US美国中南部
West Europe西欧
East US美国东部
Southeast Asia东南亚
East Asia东亚
Japan West日本西部
Japan East东日本

The other options available are:

其他可用选项包括：

Locally redundant storage stores and maintains three copies of your data in a single facility and a single region.本地冗余存储将数据的三个副本存储并维护在一个设施和一个区域中。
Geo-Redundant is the default and recommended option. This option lets you create six replicas of your data 3 in your local region and three in other region far away from the other replica. 地理冗余是默认和推荐的选项。通过此选项，您可以在本地区域中创建六个数据副本3，并在远离其他副本的其他区域中创建三个副本。
Read access geo-redundant creates replicas in a primary region and secondary read-only replica in a second region. In case that the primary replica fails, the secondary replica can be used with read-only permissions.读取访问地理冗余在主区域中创建副本，在第二区域中创建辅助只读副本。如果主副本发生故障，则可以以只读权限使用辅助副本。
Zone-Redundant storage lets you store 2-3 replicas in the same region or two different regions.区域冗余存储使您可以在同一区域或两个不同区域中存储2-3个副本。

SECRET = N'asssssddddddffqqq'
GO

Now, backup a local database.

现在，备份本地数据库。

In the Back up to option, select URL. In file name, you can write any name or keep the default values. In SQL credential, select the credential created in figure 14. In azure storage container, use the container created in figure 9. Finally, for the URL prefix, used the URL container used in the figure 10. Once this option are set, create the backup.

在“备份到”选项中，选择“ URL”。在文件名中，您可以输入任何名称或保留默认值。在SQL凭证中，选择在图14中创建的凭证。在Azure存储容器中，使用在图9中创建的容器。最后，对于URL前缀，使用在图10中使用的URL容器。一旦设置了此选项，请创建备份。

最终建议 ( Final Recommendations )

Your internet connectivity is critical if you want to work with Microsoft Azure. If your internet connectivity is not trustable, your backup and recovery plan will not be trustable either. The same for the Internet Speed. If your Internet Connectivity is not fast, restoring a 32 GB database will take hours. Test your Database in a testing environment before taking a decision to migrate to Azure.

如果要使用Microsoft Azure，则Internet连接至关重要。如果您的Internet连接不可靠，则备份和恢复计划也将不可靠。互联网速度相同。如果您的Internet连接速度不快，则还原32 GB数据库将花费数小时。在决定迁移到Azure之前，请在测试环境中测试数据库。

结论 ( Conclusion )

In this article, we show how to create a storage in Microsoft Azure, how to create a container, how to backup a local SQL Server Database to that storage and finally how to restore the database stored from the Microsoft Azure Storage.

在本文中，我们将展示如何在Microsoft Azure中创建存储，如何创建容器，如何将本地SQL Server数据库备份到该存储以及最后如何从Microsoft Azure存储还原存储的数据库。
