SQL Server 2008如何复制数据库

SQL Server 2008如何复制数据库:

方法一:使用Microsoft SQL Server Management Studio中的Copy Database Wizard来辅助完成。(很容易失败)

方法二:采取Backup/Restore的方式(推荐)

a.备份数据库到磁盘

BACKUP DATABASE Source_Database
TO DISK = 'D:\Backup\Source_Database.bak'
WITH FORMAT;

b.查看备份文件的逻辑文件

RESTORE FILELISTONLY
FROM DISK = 'D:\Backup\Source_Database.bak';

c.创建目标数据库

CREATE DATABASE Target_Database;

d.从磁盘复制数据库

/*
利用bak恢复数据库,强制还原(REPLACE)
STATS = 10 每完成10%显示一条记录
Source_Database和Source_Database_log是上面D:\Backup\Source_Database.bak里的逻辑文件
*/
RESTORE DATABASE Target_Database
FROM DISK='D:\Backup\Source_Database.bak'
WITH
MOVE 'Source_Database' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\Target_Database.mdf',
MOVE 'Source_Database_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\Target_Database_log.ldf',
STATS = 10,REPLACE
