Something about restore and bak sql server

Here is a sample for restore and bak sql server database:

alter database pubs set SINGLE_USER with rollback IMMEDIATE use master
RESTORE DATABASE pubs
FROM DISK = 'c:\pubs.bak'
WITH NORECOVERY, MOVE 'pubs' TO 'C:\xx\pubs.mdf',
MOVE 'pubs_log' TO 'C:\xx\pubs_log.ldf'
//备份
BACKUP DATABASE pubs
TO DISK = 'c:\pubs.bak'
//条目
RESTORE FILELISTONLY
FROM DISK = 'c:\pubs.bak'

(1)数据备份语句：backup database 数据库名 to disk='保存路径\dbName.bak'
(2)数据恢复语句：restore database 数据库名 from disk='保存路径\dbName.bak' WITH MOVE 'dbName_Data' TO 'c:\tcomcrm20041217.mdf', --数据文件还原后存放的新位置
MOVE 'dbName_Log' TO 'c:\comcrm20041217.ldf' ----日志文件还原后存放的新位置
关于这两个语句还有更详细的介绍：http://blog.csdn.net/holyrong/archive/2007/08/29/1764105.aspx
另外，如果出现：“尚未备份数据库的日志尾部”错误，可以在还原语句后加上 With Replace 或 With stopat
