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

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
