你的文件路径有问题: 数据库备份,执行语句: backup database 数据库名 to disk='填写要备份文件到哪个文件夹下的路径'--数据库恢复 restore database MrData from disk='F:\数据库备份\bak数据库\MrData.bak' with recovery, move 'MrData_data' to 'F:\数据库备份\佐登妮丝\MrData_data.mdf', move 'MrData_log' to 'F:\数据库备份\佐登妮丝\MrData_data.ldf' 数据库库恢复，如果上面一句代码在不同机子上的数据库执行的话， 可能会出错，找不到路径，因为在备份数据库的时候把数据库的路径也保存在里面， 所以这样恢复数据库的话，就会默认的在这个文件夹下面创建数据库
数据库备份,执行语句:
backup database 数据库名 to disk='填写要备份文件到哪个文件夹下的路径'--数据库恢复
restore database MrData from disk='F:\数据库备份\bak数据库\MrData.bak' with recovery,
move 'MrData_data' to 'F:\数据库备份\佐登妮丝\MrData_data.mdf',
move 'MrData_log' to 'F:\数据库备份\佐登妮丝\MrData_data.ldf'
数据库库恢复，如果上面一句代码在不同机子上的数据库执行的话，
可能会出错，找不到路径，因为在备份数据库的时候把数据库的路径也保存在里面，
所以这样恢复数据库的话，就会默认的在这个文件夹下面创建数据库
贴下你的BACKUP DATABASE语句.
