我需要在SQL脚本文件中自动执行SQL Azure数据库备份。 我怎么能这样做？

Question

Presently i am generating SQL scripts everyday to take the backup of SQL Azure database. I need to automate this process using some freeware. How can i achieve this?

Note:- I need to take the backup in form of SQL Script to some local machine.

Answer 1

Option 1: Run some code/script to backup the database

You could run the SQL using the SQLCMD utility.

http://msdn.microsoft.com/en-us/library/ms162773.aspx

To schedule this, just use the Windows Task Scheduler.

Option 2: Use Azure Data Sync

Keep a local database in sync with your SQL Azure database, like a constant backup.

http://msdn.microsoft.com/en-us/library/windowsazure/hh456371.aspx

Option 3: Use BacPac

There is an API available in Azure to backup your database to a BACPAC format.

http://msdn.microsoft.com/en-us/library/windowsazure/hh335292.aspx

A RedGate tool then allows you to restore to a local SQL Server.

Edit

I have since created a command line tool which will create a copy of your database, and back it up to BacPac using the Azure Management API:

Answer 2

You could try RedGate Azure Sql backup http://www.red-gate.com/products/dba/sql-azure-backup/

That can be also scheduled using Task Scheduler.

I have written some ideas on how to do that: http://anttitech.wordpress.com/2011/11/06/azure-sql-backup-and-restore-scenarios-using-bacpac-exportimport/

Answer 3

创建数据库的云端备份（以获得一致的快照），然后使用数据层应用程序框架 （DACFx）客户端工具将快照复制到本地计算机，如自动化Windows Azure SQL数据库备份中所述 。

Answer 4

I have come across a free tool that makes backups of your SQL Azure Databases. Backups can be stored locally or on blob. You can also schedule backup operations with its built-in scheduler, or use the Windows Scheduler and the provided command-line utilities.

Answer 5

SQL Azure Database does not support SQL Server Agent or jobs. You can, however, run SQL Server Agent on your on-premise SQL Server and connect to SQL Azure Database.

SQL Server Agent is a Microsoft Windows service that executes scheduled administrative tasks, which are called jobs...For example, if you want to back up all the company servers every weekday after hours, you can automate this task. Schedule the backup to run after 22:00 Monday through Friday
