sql sever 2008数据库的还原备份问题

Posted 2023-05-07

还原时出现以上问题怎么办？

你在备份的时候创建了媒体簇，但是你只拷贝了一个备份文件，处理方法有两个：

在源计算机上找到C:\\Program Files\\Microsoft SQL Server\\MSSQL10_50.MSSQLSERVER\\MSSQL\\Backup文件夹（MSSQL10_50.MSSQLSERVER这个路径可能和你的不同，根据你的SQL版本，我的是SQL 2008R2，但是MSSQL\\Backup这个文件夹肯定有），拷贝备份文件，比如你的源数据库名称为LS,那么你就拷贝LS.bak，和你刚才的备份文件放到一起，形成一个媒体簇，然后才能还原。

重新备份，备份时删除SQL SERVER的默认备份设备，再添加你的备份文件。

追问

我把他们放在一起了

然后我从新建立一个我数据库名字叫132，还原那个132的文件是出现这种情况

求解释

你的132.bak文件其中可能以前备份过数据库，你只能重新备份了。备份方法：
