===================================

sql 2000

一、指定逻辑备份设备

    backup databse accounting

    to accounting_bak

二、或指定物理备份设备

    backup database accouning

    to disk='d:\backup\accouning\full.bak'

三、执行无日志操作后的命令

    backup log with truncate_only

    writetext

    或

    backup log with NO_log

    updatetext

    select ... into....

四、设置数据库的还原模型

   1、完全模型

    alter database northwind

    set recovery full

   2、简单模型

    alter database norhtwind

    set recovery simple

   3、大容量日志记录bulk_logged模型

    alter database northwind

    set recovery bulk_logged

五、添加备份设备

   sp_addumpdevice 'disk','NWdevice','d:\backup\mydevice.bak'

六、删除一个备份设备

   sp_dropdevice 'nwdevice','delfile'

   /*如果加上delfile就是直接把文件也删除掉*/

七、差异备份的语法

   backup database northwind

   to nwdevice with differential

八、事务日志备份

   backup log company to NWdevice with   no_truncate（不清空原有日志）

九、文件和文件组备份及还原

   backup database commpany

   filegroup='primary' to NWdevice

   文件组的名称是"primary"

十、数据恢复(从硬盘恢复)

   restore database company from 

   disk='d:\backup\company.bak'

   还可继续在后面加参数：

   with nonrecovery recovery replace

   注：                 

   (1)recovery:最后一次一次恢复时使用     

   (2)replace：是否替换己有文件

十一指定还原后的数据库物理文件名称及路径

RESTORE DATABASE TestDB

   FROM DISK = 'c:\Northwind.bak'   WITH   MOVE 'Northwind' TO 'c:\test\testdb.mdf',   MOVE 'Northwind_log' TO 'c:\test\testdb.ldf'

   MOVE 'logical_file_name' TO 'operating_system_file_name'
