如何创建（使用 sql 代码）完整、差异和事务日志备份

Question

我想生成 3 个备份脚本，一个完整备份，一个差异备份和一个事务日志备份。

假设我们使用 northwind。我如何生成这些脚本？

如果有人能一步步描述，我将不胜感激。

Answer 1

完整备份的方法如下：

USE AdventureWorks2008R2;
GO
BACKUP DATABASE AdventureWorks2008R2
TO DISK = 'Z:\SQLServerBackups\AdventureWorks2008R2.Bak'
--optional
   WITH FORMAT,
      MEDIANAME = 'Z_SQLServerBackups',
      NAME = 'Full Backup of AdventureWorks2008R2';
GO

这是日志备份：

BACKUP LOG MyAdvWorks_FullRM
   TO MyAdvWorks_FullRM_log1;
GO

当你有一个完整的备份时你可以使用备份设备来执行延迟备份：

-- Create a full database backup first.
BACKUP DATABASE MyAdvWorks 
   TO MyAdvWorks_1 
   WITH INIT
GO
-- Time elapses.
-- Create a differential database backup, appending the backup
-- to the backup device containing the full database backup.
BACKUP DATABASE MyAdvWorks
   TO MyAdvWorks_1
   WITH DIFFERENTIAL
GO

在 MSDN 中确实应有尽有：
