---还原之后可以直接使用
RESTORE DATABASE [lys_12] FROM  DISK = N'D:\liyuanshuai\test\sqlserver_bakfile\lys20241219.bak'
WITH  FILE = 1, 
MOVE N'lys' TO N'D:\liyuanshuai\test\sqlserver_bakfile\lys\lys_12.mdf',  
MOVE N'lys_02' TO N'D:\liyuanshuai\test\sqlserver_bakfile\lys\lys_12_02.ndf', 
MOVE N'lys_sec' TO N'D:\liyuanshuai\test\sqlserver_bakfile\lys\lys_12_sec.ndf',  
MOVE N'lys_if' TO N'D:\liyuanshuai\test\sqlserver_bakfile\lys\lys_12_if.ndf',  
MOVE N'lys_log' TO N'D:\liyuanshuai\test\sqlserver_bakfile\lys\lys_12_log.ldf', 
MOVE N'lys_log2' TO N'D:\liyuanshuai\test\sqlserver_bakfile\lys\lys_12_log2.ldf',  
NOUNLOAD,  STATS = 5

分阶段还原，先还原全备，使数据库处于noreovery状态，然后再还原日志备份
