--完整备份
Backup Database NorthwindCS
To disk='G:\Backup\NorthwindCS_Full_.bak'

--差异备份
Backup Database NorthwindCS
To disk='G:\Backup\NorthwindCS_Diff_.bak'
With Differential

--日志备份，默认截断日志
Backup Log NorthwindCS
To disk='G:\Backup\NorthwindCS_Log_.bak'

--日志备份，不截断日志
Backup Log NorthwindCS
To disk='G:\Backup\NorthwindCS_Log_.bak'
With No_Truncate

--截断日志不保留
Backup Log NorthwindCS
With No_Log

--或者
Backup Log NorthwindCS
With Truncate_Only
--截断之后日志纹件不会变小
--有必要可以进行收缩

Exec Sp_Helpdb NorthwindCS --查看数据纹件
Backup Database NorthwindCS
File='NorthwindCS' --数据纹件的逻辑名
To disk='G:\Backup\NorthwindCS_File_.bak'

--纹件组备份
Exec Sp_Helpdb NorthwindCS --查看数据纹件
Backup Database NorthwindCS
FileGroup='Primary' --数据纹件的逻辑名
To disk='G:\Backup\NorthwindCS_FileGroup_.bak'
With init

--分割备份到多个目标
--恢复的时候不允许丢失任何一个目标
Backup Database NorthwindCS
To disk='G:\Backup\NorthwindCS_Full_1.bak'
disk='G:\Backup\NorthwindCS_Full_2.bak'

--镜像备份
--每个目标都是相同的
Backup Database NorthwindCS
To disk='G:\Backup\NorthwindCS_Mirror_1.bak'
Mirror
To disk='G:\Backup\NorthwindCS_Mirror_2.bak'
With Format --第一次做镜像备份的时候格式化目标

--镜像备份到本地和远程
Backup Database NorthwindCS
To disk='G:\Backup\NorthwindCS_Mirror_1.bak'
Mirror
To disk='\\192.168.1.200\Backup\NorthwindCS_Mirror_2.bak'
With Format

--每涛铤成一个备份纹件
Declare @Path Nvarchar(2000)
Set @Path ='G:\Backup\NorthwindCS_Full_'
+Convert(NvarcharGetdate()112)+'.bak'

Backup Database NorthwindCS
Todisk=@Path

--从NoRecovery或者
--Standby模式恢复数据库为可用
Restore Database NorthwindCS_Bak
With Recovery

--查看目标备份中的备份集
Restore HeaderOnly
From Disk ='G:\Backup\NorthwindCS_Full_.bak'

--查看目标备份的第一个备份集的信息
Restore FileListOnly
From Disk ='G:\Backup\NorthwindCS_Full__2.bak'
With File=1

--查看目标备份的卷标
Restore LabelOnly
From Disk ='G:\Backup\NorthwindCS_Full__2.bak'

--备份设置密码保护备份
Backup Database NorthwindCS

To disk='G:\Backup\NorthwindCS_Full_.bak'
With Password = '123'init

Restore Database NorthwindCS
From disk='G:\Backup\NorthwindCS_Full_.bak'
With Password = '123'
