SQL Server:备份所有数据库 [英] SQL Server: backup all databases

问题描述

我想知道是否有任何方法可以定期将整个SQL Server(我们正在使用SQL Server 2008)备份到特定位置.我知道我们能够备份单个特定的数据库，但是为了易于使用，并且每次我想要一个新数据库时都不必设置备份，有没有办法做到这一点?

I was wondering if there was any way of making a backup of an entire SQL Server (we are using SQL Server 2008) at regular intervals to a specific location. I know we are able to backup single specific databases but for ease of use and not having to set up a backup each time I want a new database, is there a way to do this?

但是，如果有的话，我必须有一种方法可以轻松地从该服务器备份中还原单个数据库，就像我已经分别备份它们一样.

If there is however, I must have a way of restoring just a single database from that server backup easily as though I have backed them up individually.

所使用的方法仅是纯备份，没有区别，因此无需担心复杂性.

The method used will just be a pure backup and not a difference so no need to worry about complications.

推荐答案

您可以运行以下脚本，只需将@path变量更改为要存储数据库的位置.

You can run the following script, just change the @path variable to where you want to store the databases.

DECLARE @name VARCHAR(50) -- database name  
DECLARE @path VARCHAR(256) -- path for backup files  
DECLARE @fileName VARCHAR(256) -- filename for backup  
DECLARE @fileDate VARCHAR(20) -- used for file name 

SET @path = 'C:\Backup\'  

SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112) 

DECLARE db_cursor CURSOR FOR  
SELECT name 
FROM master.dbo.sysdatabases 
WHERE name NOT IN ('master','model','msdb','tempdb')  

OPEN db_cursor   
FETCH NEXT FROM db_cursor INTO @name   

WHILE @@FETCH_STATUS = 0   
BEGIN   
       SET @fileName = @path + @name + '_' + @fileDate + '.BAK'  
       BACKUP DATABASE @name TO DISK = @fileName  

       FETCH NEXT FROM db_cursor INTO @name   
END   

CLOSE db_cursor   
DEALLOCATE db_cursor
