SQL在磁盘上创建了一个备份设备

Posted 2023-05-07

USE [master]
GO
EXEC master.dbo.sp_addumpdevice
@devtype = N'disk',
@logicalname = N'test_backup',
@physicalname = N'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Backup\1.bak'
GO
以上各行命令麻烦各位大侠解释一下，知道多少说多少，当然是越详细越好，谢谢啦

USE [master] 使用master库
GO 执行
EXEC master.dbo.sp_addumpdevice 执行master库中的master.dbo.sp_addumpdevice 过程
@devtype = N'disk', 参数一：设备类型:硬盘
@logicalname = N'test_backup', 参数二：设备名称（逻辑名称）：test_backup
@physicalname = N'C:\Program Files\Microsoft SQL Server\MSSQL.1 \MSSQL\Backup\1.bak' 参数三：物理名称(备份文件路径)
GO 执行 参考技术A master.dbo.sp_addumpdevice用法可参考

这是系统中sp_addumpdevice存储过程的原型

恢复帐套时提示“已备份数据库的磁盘上结构版本为611.服务器支持版本539,无法还原或升级数据库。”

恢复帐套时提示“已备份数据库的磁盘上结构版本为611.服务器支持版本539,无法还原或升级数据库。”，该如何处理？

概述：
611是指sql 2005的版本，539是指sql 2000的版本，SQL 2005的数据库备份是不能在sql2000的数据库上还原的。直接安装SQL2005后再恢复该数据库使用。 参考技术A 两个方法1.升级现在的数据库到20082.找一台2008把数据库挂上,用导入导出的方法把数据导入到你这台2005上(步骤比较麻烦) 参考技术B 两个方法
1.升级现在的数据库到2008
2.找一台2008把数据库挂上,用导入导出的方法把数据导入到你这台2005上(步骤比较麻烦)
