这里的备份恢复是指用命令

备份

BACKUP DATABASE [SnPrintZC] TO  DISK = N'F:\sqlbackup\sp2' WITH NOFORMAT, NOINIT, 
 NAME = N'备份说明', SKIP, NOREWIND, NOUNLOAD,  STATS = 10

SnPrintZC 数据库名 disk 备份路径绝对值

恢复

RESTORE DATABASE [SnPrintZC] FROM  DISK = N'F:\sqlbackup\sp2' WITH  FILE = 1,  NOUNLOAD,  STATS = 5

脱机

ALTER DATABASE [SnPrintZC] SET OFFLINE WITH ROLLBACK IMMEDIATE; 

状态

select name,state_desc from sys.databases

查看进程

EXEC sp_who2 

杀死

KILL 1

恢复

恢复的时候，先做脱机处理

1 先看数据库是否还有人用 EXEC sp_who2

2 如果有人用 杀死进程 KILL 1 （1 为 EXEC sp_who2中返回的结果中使用数据库的pid）

3 执行脱机 ALTER DATABASE [SnPrintZC] SET OFFLINE WITH ROLLBACK IMMEDIATE;

4 查看数据库是否脱机 select name,state_desc from sys.databases

5 执行恢复命令 RESTORE DATABASE [SnPrintZC] FROM DISK = N'F:\sqlbackup\sp2' WITH FILE = 1, NOUNLOAD, STATS = 5
